Low emission of carbon, alternative energy sources to promote the national car industry must PA3191U-4BRS  PA3285U-1BRS

The implementation of new energy projects is in line with the country’s energy security and strategic needs of environmental protection, scarcity of energy resources in oil today, as development Blood economic power has been directly linked to the strategic security of the national economy. Currently, the energy industry has become the new developed and developing countries competing for the strategic industry of the new century an important symbol of the overall strength of domestic industries.

Electric Vehicle State “Shier Wu,” The sense key driver of discount subsidy to encourage car manufacturers a way to monitor the adoption of the 20 cities in 100 Taiwan bus power, in the last three years, demand for battery power market are a bit beyond 10 billion by 2015 could reach about the past hundreds of billions of market share.

Carbon emissions have become a global center, while car pollution of the social environment more and more serious became a significant reduction targets for reducing emissions of greenhouse gas emissions. TravelMate 290 battery BATBL50L6 Currently, the automotive industry in the world of developed countries, cycle emissions of carbon dioxide each year to clear standards to reduce emissions. This shows that electric vehicles to replace vehicles with internal combustion engine on the environment and reduce consumption of conventional energy sources have an important role in developing the production of electric vehicles is already a social development and economic security of major strategic issues. To meet the requirements of electric vehicles, considered the core of the electric car, the battery is the key. Polymer-lithium-ion battery is the high level of battery technology, it will be the emergence of China is an essential driver technology and automotive products.

In 2010, the company will take this opportunity, planning and domestic and foreign car manufacturers to work closely and actively promote the hybrid vehicle the pace of development will be completed with the bus 100 corresponding battery power (EV ) and the hybrid battery-300 sets (HEV).

Believe that large-scale production will be lithium-polymer of the China-ion batteries for a new starting point. Sony VGP-BPS8 Sony VGP-BPS8A Powered vehicle market in the rich harvest the fruits of power cars will play a positive role in promoting. Weihai Dong-sheng energy will contribute to the cause of environmental emissions of China thin edge to become a new bright spot in the industry.

When your phone time to use shorter VGP-BPS10 VGP-BPS8 battery (memory effects or aging), you need a battery to replace it?

The next time you encounter this situation when you save your money, you say a very effective way to test:

1, the battery in the newspaper before being placed in plastic bags, wrap well into the freezer for three days (the logs can absorb excess moisture)

2, three days after the transfer of two days at room temperature

3, two days after charging the battery, mobile phone charge saturation test wrap yellow (estimated to save 80% -90%).

The information revealed by the well-known manufacturers’ engineers’ battery, according to a friend pointed out that the effects tested to be effective. Like any effect, anyway, the 346970-001 367759-001 battery faster useless, but everyone has a refrigerator, ladies and gentlemen may want to try it!

I try to explain! This method is not my own creation, is the professional way! May we wish to try!

Battery Internal battery fluid, because the battery aging, because the liquid solidified lead battery. The solution is to put the battery low freezing temperature, so that the liquid solidified battery, let it melt naturally, drawing excess water, then fully charge the battery fluid to all assets, fair another new.

Really very helpful in giving you a reference!

A popular recipe for lithium current fixed telephone line-testing methods of ion battery!

Cell phones are now used in our daily life, electronic products used most frequently, and walk in the street, almost irrespective of young and old, rich or poor, nearly one or more labor, as I remember when he no longer get those bags of money a “Big Brother” so that those areas. But tell the truth, now that the popularity of mobile phones, and indeed the link is to make life more comfortable. Dell Inspiron B120 battery  Dell Inspiron B130 battery

I started using mobile phones to now she has replaced all four, and an early monochrome screen Motorola Samsung Anycall, was recently replaced by another Nokia N95, more functionality and use of cell phones have become increasingly frequent Consequently, the cell phone battery is a test, and take the N95 I use the example of this bar, every day is an hour or a normal voice calls, send text messages, then the time is probably ten to twenty minutes, of course, songs and games, is almost an hour, it probably also be able to adhere to three days or less.

A few days ago the battery in the search for information online and found a lot about the restoration of the position of the old battery, just wanted to come to his house and several of these batteries are old machines at rest, it introduced a better test, but also a look at these methods in the end is not feasible. A1078 A1175

The first is the freezing method: close to limit the use of mobile phone batteries in the refrigerator, freezer for three days, a chance to continue to use, battery life longer than the pre-frozen! This is the latest rumor on the Internet fix old battery, I will introduce the first of this surgery 啦!

Motorola to first find the battery, this machine is still seven years ago, V70, a rotating screen, now he can give a child a toy, and inside the battery is original, and End CECT load placed over two days is probably no electricity, and remove the battery with two layers of plastic wrap and two layers of paper bag, which is hygroscopic moisture, Fang Bingxiang cold freezer for three days, then remove the packaging and then dried for two days, charging the phone that the mobile phone of the third day without electricity only at night, it seems that this approach is really having some effect.

This approach to online professional explanation is as follows: mobile phone battery loading and unloading process is a process in the meantime, the battery in the yin and yang with the other to pay the amount received. The reason the battery will be more and more without the use because the normal room temperature, the electron kinetic energy in the relatively large, and the battery is in an active state, where the leak is relatively frequent. But the PA3399U-1BAS PA3399U-1BRS battery in the mid to low temperature, the surface of the lithium electrolyte membrane and the micro-structure, and their interfaces are changed significantly, leading to cells in assets temporarily to reduce the current drain, if the charging, cell phone to be switched on time will increase.

For this interpretation, I am not a physics does not know the right end wrong with that.

The second argument, using an eraser wipe the batteries of mobile telephones and cellular telephone contact with the surface of contact with the metal, allowing the use of the situation of mobile batteries is a great good.

This principle is still relatively easy to understand will be a long time to surface oxidation of metals, a natural touch to close to the battery also used for short time. I use my mobile phone batteries Samsung to do experiments, do not use an eraser, and found sandpaper polishing, folded in half, using the tips of cell phone battery touch of polished brass few films, then wipe clean sheet again fully discharge and then charge the battery than the original multi-purpose room of the day, it seems that there are still effects.

A third argument is given near the demolition discharge the battery completely, then recharge the battery is activated. BATBL50L6 LCBTP03003

This does not seem many people have tried, I happen to have a battery backup is an old Samsung mobile phone battery may be used improperly, the base will be less than one day is left to rest in a drawer are more than two years. I was looking for a two-wire, connected to a small 1.5 volt bulb, and then received a wire at both ends and then the battery positive and negative, light bulbs reluctantly gave a little light, lasted less than half an hour, the bulbs will be brighter, rechargeable, but also more specifically in charge for two hours on the phone, this time to maintain more than one day before the black cell phone, and if this kind of method is still capable of quite useful.

Three kinds of methods, 11 had tried the first two are relatively easy, my friends, you can try in a test, but that said, the rich friends might think this is very troublesome patch, think about mobile phones is relatively commodity is relatively expensive and a thousand dollars to buy a cell phone, buy 12 saving high-performance battery-May be more realistic, original electric Xiangui, then the power of the brand is actually quite made a good choice. I am now in addition to original Nokia batteries purchased a block away from the Hong-yi, and with them I felt the original sounds like there is not much difference. Two batteries in hand, met a traveler also no longer need to worry about what Shoujimeidian. FRU 92P1141 40Y6799

Well, writing a lot, but his conclusion that the experiments, we also tried if these measures are welcome to come to Gent, the results of the experiment, or have a better way, they might as well share it!

Li-ion battery memory effect will be

Many friends believe that the power lithium battery must be used, or memory effect may also occur, in fact, this concept was first nickel cadmium batteries, nickel-cadmium batteries are the memory effect, so let him go to make electricity, the Laptop battery will be increased with the frequency of use while showing less and less state energy, and later nickel-metal hydride battery has been improved, had no obvious memory effect, because the nickel-metal hydride battery or will a certain degree of lattice leads to volume reduction still need to complete the regular charge and discharge to maintain its ability normal. Lithium batteries there was virtually no memory effect, you can at any time without affecting the battery charge and discharge capacity.

From another point of view, the memory effect of the battery refers to battery failure reversible, that is, after the failure of the battery can be re-back performance. The lithium battery is not reversible, performance and capacity continue to decline as the use of, there is no lithium batteries memory effect, another, thus eliminating the need for charging the deep memory of the deep cycle battery, which is the battery voltage to reach 1.0V, mobile phones can not stick to the battery voltage to 1V off their phones before nickel cadmium batteries require specialized equipment to conduct such a depth of discharge.

To summarize, there is no lithium batteries memory effect, the user need not worry, we can agree with the birth of lithium batteries is to eliminate the problems caused by the ‘memory effect, so that you can recharge the Dell Inspiron 5100 battery at any time without any worries.

The new lithium batteries are necessary to activate

This is an old subject, a majority of consumers is necessary to activate the battery, almost all of the sales staff so that the battery is first three full 12 hours, and to activate the battery. Most consumers do, and some people poor battery performance attributed to the activation of the battery is not good.

So do batteries need to activate? The answer is yes, you need to activate! However, this process is completed by the manufacturer, has nothing to do with the user, the user had no means complete. Lithium batteries actual activation process is as follows: lithium-ion battery electrolyte impart SHELL – Seal – as it is a constant voltage, then discharge, so for a few cycles, so that complete infiltration electrolyte electrode fully activated until the date requested capacity, the activation process – under capacity, which means that after the lithium-ion battery plant to the user is already turned off the hands of the. In addition, some processes require the activation of the hp Business Notebook nx7400 battery cell in the state open again after closing, unless you have batteries, manufacturing equipment, or how to accomplish?

But why some descriptions of products able to read, easy to use three primary users should be on the phone a full charge and discharge? Is it not to activate? Indeed, the fact is that the factory battery, then the sale, then the hands of the user should experience a period of time, one or more months in this way, the battery materials electrodes will be “passive”, proposed the initial specification using the three fastest times of the fully charged battery-discharge process, to quickly eliminate passivation of electrode materials to achieve the highest performance. However, this process does not require a full 12 hours, it must be completed. In fact, we ignore this point, the normal period of time can also be used to eliminate passivation.

Li-ion battery can load and unload 500 times

I think the vast majority of consumers have heard the sony VGP-BPS2A battery life of lithium is “500 times, 500 charge and discharge more than this number, the battery on the” end “, and many friends to be able to prolong battery life, each time in to recharge the battery when it is completely exhausted, and thus extend the battery life really works? The answer is no.

In fact, there is a conceptual error, the battery life of lithium is “500 times” refers not to the frequency of recharging, but a charge-discharge cycles, for example, the first charge of 40% with a period of time and later occupied by 20%, other and later used a load of 30%, then the next … 20% … 20% in the middle, or only 10% of electricity when the cumulative total to complete a charge cycle. Followed by the next cycle.

1 lithium-ion battery on the first day, only half the electricity, and then it is fully charged. If the next day too so, ie with half the load, a total of two charge down, this can not be counted as one charge cycle, rather than two. Thus, it is usually possible to cross several times to complete a charge cycle. Each complete a charge cycle, energy consumption will be reduced somewhat. Once However, the reduction of the amplitude is very low, high cycle toshiba PA3399U-2BAS battery quality of many officials will retain the original capacity of 80%. Suppose a complete discharge of electricity is the Q, a cell cycle 500 times, it is then subject to the life of the total power is 500Q, if we use half the electricity load, fixed number of charge cycles for A, a simple solution, a / 2Q * A = 500Q, A should be 1000. So for the life of the battery, you can use the measurement cycle, but we do not use numbers to quantify.

The pursuit of high performance and overload in relation to rejection

Some of our friends in pursuit of battery performance, as over-charging and discharging of the battery. Lithium-ion batteries that will cause permanent damage to the positive and negative, from the molecular level of intuitive understanding, an excessive discharge of carbon anode will lead to excessive release of lithium-ion and shows a lamellar structure collapsed, too much will overload the lithium-ion structure in hard carbon going into the anode, causing some of the lithium-ion batteries can not be released. Therefore, lithium-ion BATBL50L6 batteries are usually equipped with charge control circuit causes discharge.

In addition, most cell phones now use pulses of high current at full load to nearly full power quickly when the overpayment, to prevent the circuit from the pulse high-current is converted a gradual reduction of the burden of maintenance, so even if the power to detect some bias due to the most comprehensive electric current is smaller at the last minute of the load current is near 0. So for these devices load, overload is also a wasted effort.

For the performance of lithium batteries used in 100, after reaching a peak is also false to assert, for liquid lithium-ion batteries, but there is no such phenomenon hump cycle capacity lithium battery factory ion batteries in the final retreat, the performance of its capabilities is to use a short time, the performance cycle will not rebound.

Increasingly pressing problem of climate change, the ability to Copenhagen for control of the temperature rise in 2 ℃ target relates to the serious problem of human existence. It is generally expected, and Costa will be the focus of the participating countries will focus on specific commitments to reduce emissions, analysts believe it will contribute directly to the new energy industry of the Laptop battery and the development of green lighting.

New Energy Battery Industry: program benefits new energy vehicle development

According to media development and reform of the Commission motor team leader Wang Shulin, has revealed “new energy program for vehicle development was presented to the Council of State should officially promulgated in March 2010. In addition, State agencies will also be launched next year, development of new energy vehicles for the five accompanying measures. Analysts estimate that the new energy industry of the battery will most benefit from the concept of new energy vehicles.

The new energy vehicles in March next year, introduced the planning or

If the concept of energy market news, sauteed, in policy came good constantly. Held recently in Nanchang, the new energy vehicles and lithium-ion batteries feature forums, the National Development and Reform Commission automobile team leader Wang Shu-lin said that China will soon release of new energy vehicles, specifications techniques, and new energy vehicle development presented by Development and Reform Commission of the State Council, was officially promulgated in March next year.

Industry analyst with CITIC Securities automotive Cheng believes that this concept for some companies, the new toshiba PA3191U-2BRS battery energy as Shanshangufen, Jiangsu Guotai other battery manufacturers to make more, but for the entire automotive sector in particular, SAIC, FAW and other great little effect on car companies. Energy vehicles would be the automotive industry and its upstream segment of the cell concept of society have an impact. March release, “the restructuring of the auto industry and the revitalization plan” submitted in 2011 to form a production capacity of 500,000 short-term goal, which is currently more than 1300 million units for the production of the automotive industry is concerned, a very small proportion of new energy vehicles. For their own societies smallest battery to the past, mainly the provision of mobile phones, computers and other battery-quarter production traction batteries, 500,000 will be a huge volume of activity, hence the emergence of new energy concepts will greatly enhance the performance of these companies.

From March 2009 “published by the restructuring of the automotive industry and the revitalization of planning” in response to vehicles with new energy into the electric car, Development and Reform Commission has been clearly put forward in 2011 to form a production capacity of 500,000 short-term goal. It is understood that electric vehicles, power batteries, electric motors, power electronics, the cost of key components, which represents the cost of BATBL50L6 electric vehicles by 30% -50%. Based on the calculation of 500,000 electric vehicles with a value of annual production expected to reach 1,000 billion yuan.

Previously, the two countries issued a joint statement in Beijing, the two sides agreed during the next five years, Sino-US Joint Research Center of the investment for clean energy at least 150 million U.S. dollars the priority research topics will own cars. The market believes that Sino-US Joint Declaration on cooperation in energy sources such as news, digital, relatively rare in history, new energy vehicles are expected to form a positive plate material.

The State Council Development Research Center of Industrial Economics Research Department, Feng Fei energy experts believe that both parties should take the initiative in the field of electric vehicles for cooperation, Chinese electric vehicle is a huge market and cost advantage manufacturing, but the overall level of automotive, industrial technology, the infrastructure was not enough, the United States, it is precisely in this area has a great advantage if both parties take the initiative in the field of electric vehicles to launch a new type of automotive products, will become a reality.

Automotive Li-ion batteries to double next year transfers

As environment-friendly vehicles worldwide are sought, the hybrid electric cars and sells the coming years, the automotive market lithium will develop rapidly. Fuji Institute of Economic Research said that from the 2010 car market lithium batteries will quickly recover and continue to grow. The report predicts that by 2014, manufacturers of batteries that the overall amount of total shipments in 2008 increased by 45.2% to 6.2392 billion yen. Among them, rechargeable apple A1022 battery market will be extended to 4.9983 billion yen, an increase of 66.8%. It should be noted that the needs of the automotive industry will become the main engine of expansion of the battery market is expected in 2009 shipments of lithium batteries automotive sector will amount to ¥ 10,400,000,000 in 2008, based on double ¥ 25000000000; In 2014, the market size will expand rapidly to 2.25 billion yen, or about 215 times in 2008.

Management Consulting International firm Roland Berger Strategy on the global outlook for new energy vehicles in the last research report predicts that by parts of the electric power in 2020, China is the drive assembly and components market worth 10 billion euros Chao, whose 2011, 2014 and 2017 the market value of 600 million euros, respectively, 2.4 billion and 56 billion euros, the estimated market value of the environment in 2020 will reach 6.5 billion euros, even a conservative estimate will reach 2.4 billion euros. According to forecasts the next 10 years, Chinese enterprises in the hybrid and electric vehicles future developments in the field have an advantage, in particular, the basic components, including developments in the field of battery has a great potential because Chinese companies have the advantage of cost of raw materials, manufacturing equipment and labor cost advantage.

According to Roland Berger predicts that 2020 will be the main markets in Western Europe, electric vehicles and plug-in hybrids will be more than 3 million in annual sales, China ranked second to reach 1.58 million of units.

With the plug-in hybrid electric vehicles of all relevant factors, the Roland Berger predicts that by 2020, elements of the VGP-BPL10 battery of the global market share in the largest share of the market size of EUR 9,600,000,000 — 297 between. Now that the Chinese suppliers and Japan, South Korea, North America, Europe, the supplier has a significant cost advantage compared to, the future of the standard battery of quality, durability and differences prices will become increasingly small.

Roland Berger estimates that the demand for battery electric vehicles will be the future of lithium the main source of output growth is expected for 2020, there will be eye-catching 70% of average annual compound rate of growth. Despite the significant growth in demand, but because of higher reserves, experts do not believe that the production of lithium will be a shortage, but there may be a price increase in the risk of a temporary existence.

Promising varieties of independent innovation of automotive batteries

Shenyin analyst Wang said that under optimistic about new energy policies to promote investment opportunities in the automotive battery industry, promising varieties of independent innovation of automotive batteries. Shenyin the next 3-5 years, Ni-MH batteries, HEVs will remain the mainstream of new energy vehicles, HEVs will PH EV, EV co-existence about 10 years. In 3-5 years later, with iron to increase the performance of lithium phosphate to lower costs, and the national network of charging stations in place progressive lithium iron phosphate as the main engine PH of the EV, EV mark the beginning of a broad development prospects. Recommended Keli far Shanshangufen, Jiangsu Guotai, Tibet mining.

Shenyin should grant political future, and the rate of localization is likely to hook. In the development strategy, pending the countries new energy vehicles as an opportunity to catch up from behind their own technology. I believe Sino-US cooperation, China will continue to insist on independent R & D path. Possible future introduction of new energy standards car allowance, spare parts and the main rate of localization will be linked to, and encourage the autonomy of key parts as soon as possible and depending on the location of raw materials. At the same time the state will improve the access threshold, and rigorous review system products.

Shenyin should follow the state ministries and commissions, will be introduced to encourage large-scale electrical vehicles and the development of specific incentive policies. The industrialization of new energy vehicles, including the most important policy for consumers to buy new energy vehicles are subsidized, and the development of new VGP-BPS13A/B energy vehicles and infrastructure planning. The introduction of these two policies that will address bottlenecks in the consumption and use of the bottleneck.

The fundamental conditions of the membrane

The main function of the isolation cell membrane ion conduction electron, which is positive and negative electrodes in the batteries to prevent the direct electronic contact, but the free passage of ions. For lithium-ion battery separator, the basic requirements are as follows:

1. Thickness

For consumer-type lithium-ion battery (mobile phones, laptops, digital cameras, used in batteries), 25-micron membrane gradually became the norm. Membrane However, due to the increasing use of people with handheld devices, thin membranes, eg 20 microns, 18 microns, 16 microns, and even thinner started large-scale applications. For the Laptop battery power, because the requirements of mechanical assembly processes, often require thicker membrane, of course, with large batteries for power, security is also very important, while the membranes are often thicker also means better security.

2. Ventilation rate:

From academic point of view, the membrane is inert in the battery, that divide is not a necessary element of the stack, but only the production of industrial batteries. The existence of the membrane first encounter it does not deteriorate the electrochemical performance of the battery, mainly in the internal resistance. Electrolyte membrane containing the resistivity and the resistivity of the same electrolyte, the ratio between the numbers of known MacMullin. In general, consumption of lithium-ion batteries this value is close to 8, of course, this value is smaller, the better. In general, lithium-ion Dell Inspiron 6400 battery separator containing a parameter of the permeability, or called the number Gurley. This number is well defined, ie a certain amount of gas in certain pressure conditions, through a certain area, divide the time required, the volume of gas flow is generally 50cc, some companies will be marked 100cc with the final results will be twice as bad. Size should be 1 square inch pressure difference does not remember clearly. This value in a certain sense, and use their cell membrane of the internal resistance is proportional, that is, the higher the value, then the greater the resistance. However, a different membrane, the direct comparison of numbers does not make sense. Because the internal resistance of lithium-ion batteries and ionic conduction, while the ventilation rate and the spread of gases linked to two types of mechanism is not the same. In other words, the simple comparison of two different fracture Gurley number is meaningless, because she may divide two types of micro-structures are completely different, but the Gurley number of the same size of the membrane can be very good response from the size of the resistance, because the membrane is relatively the same micro-structure is identical or comparable.

3. Infiltration degrees:

To ensure internal resistance of the hp F2024A battery is not too demanding membrane is used in the electrolyte of the battery can be completely infiltrated. Government is not recognized testing standards. Can be roughly judged by the following experiment: Take a typical electrolyte (such as EC: DMC = 1:1.1 M LiPF 6), decreased membrane surface area, to see if the droplets will rapidly disappear by absorption the membrane, so it is essential to meet the infiltration requirements is illustrated. More accurate tests can be time-resolved ultra-high camera recording of the diaphragm into contact with droplets droplets disappear processes, computer time, the length of time to compare the two types of degree of membrane penetration. Infiltration degree one hand, a membrane material itself bound to another membrane on the surface and internal microstructure closely linked.

4. Chemical Stability:

In other words, is to make membranes in the electrochemical reaction is inert. After several years of industrial inspection, is generally considered that the current PE or PP separator material is chemically inert to meet the requirements.

5. Open:

In general, the membrane electrode particles to avoid direct contact, a very important point are to prevent the electrode particles directly through the diaphragm. Electrodes currently used in 10 micron particles in the general order of magnitude, while the use of BATBL50L6 conductive additives in the order of 10 nm, but had the chance to reunite the general carbon black particles tend to form large particles. In general, sub-micron pore size membrane enough to prevent particles directly by the electrodes, of course, does not exclude some of the surface of the electrode is not managed properly, leading to some of the dust over as micro-circuit short and so on.

6. Puncture Strength:

This parameter is not flat because the surface of the electrode, and the assembly process of limited technological level has applied, requiring considerable force perforated diaphragm. Tests for resistance to puncture is the industry standard to follow, usually within a certain speed (3-5 m per minute), so there is no sharp edge of a 1 mm diameter needle attached to the diaphragm ring to penetrate the membrane applied to the needle from the puncture strength of the strongest known. Similarly, because when the testing methods used and the actual situation of batteries vary considerably, the direct comparison of the two types of membrane puncture strength is not very reasonable, but in the micro-structure of certain circumstances, the strength of perforation relatively high rate of improper assembly is low. But the mere pursuit of power punching high, will inevitably lead to performance degradation of the membrane of another.

7. Thermal stability:

Diaphragms need to use the range of sony VGP-BPS2 battery temperature (-20C ~ 60C) to maintain thermal stability. Generally speaking, the current use of PE or PP is membrane materials to meet these requirements.

There is of course due to the electrolyte to water sensitive, and most manufacturers in the liquid injection around 80C before cooking, which is PP / PE membrane will not be a big problem there

8. Thermal Shutdown Temperature:

Contents of a more serious owing to security concerns, the current lithium-ion battery separator are generally able to provide an additional function, namely thermal shutdown. The general principles, we shall batteries (two flat electrodes sandwiching a diaphragm, using a common lithium-ion battery electrolyte) heating, where the resistance has increased three orders of magnitude when the temperature is called temperature thermal shutdown. This feature can be lithium-ion battery to provide extra security. Effectively close the temperature and the melting point of the matter itself closely related, such as the PE of about 135C. Of course, another micro-structure of the thermal shutdown temperature has an impact. But for small batteries, thermal shutdown mechanism for the role is very limited.

9. Rate of porosity:

Current form, the lithium-ion battery separator porosity of 40%. The pore size and the internal resistance of a certain relationship, but different types of membranes between the absolute value of the void fraction can be directly compared.
