Today, more and more people drive cars. Cars make our lives easier, but they also make problems. One of the biggest problems is air pollution, because most cars use petrol (汽油). So the “green” cars will become popular. It means that there will be a few new kinds of cars that don’t use petrol. Here are some of them:
Battery (电池) Cars: These cars use batteries to run. Some battery cars are 97% cleaner than petrol cars. But car factories still can’t make a battery that can be used for more than a few hours.
Fuel Cell (燃料电池) Cars: Car makers are now studying how fuel cells can be used to run cars. The only useless thing they will give out is clean water. Fuel cells, however, are still much too expensive to make. Fuel cell cars can be 10 times as expensive as petrol cars.
Solar (太阳能的) Cars: This kind of car gets power from the sun. The cars hold power in batteries. Solar cars may be the cleanest of all. But no one uses them, because people can’t get enough power from the sun to make a car run for a long time. Also, they are very slow.
今天，越来越多的人开起了汽车。汽车使我们的生活更轻松，但他们也造成了很多问题。最大的问题之一是空气污染，因为大多数汽车使用汽油。因此，“绿色”汽车将变得流行起来。这意味着将有一些新种类的汽车不使用汽油。这里有一些例子：
电池汽车，这些汽车使用电池运行。一些电瓶车是97%比汽油车更清洁。但汽车的工厂仍然不能制造出一个可用于超过几个小时的电池。
燃料电池汽车：汽车制造商正在研究如何将燃料电池应用于开汽车。这类汽车排放唯一无用的东西就是清洁的水。但是燃料电池仍然过于昂贵，燃料电池车比汽油车贵十倍。
太阳车，这种车从太阳获得能量。汽车把能量储存在电池中。太阳能汽车是最干净的。但没有人使用它们，因为人们不能从太阳中获得足够的力量来开很长时间的汽车。而且，太阳车非常慢。

现今越来越多的人以车代步。车辆可以使我们的生活更加便利，但他们也会带来麻烦。其中一个最大的麻烦就是空气污染，因为大部分车辆使用汽油作能源。所以“环保（绿色）”汽车将会变得更加流行。意思是说将会出现几种新型的汽车不用汽油即可行驶。以下是他们中的一些类型：
电池汽车：这些汽车用电池作能源行驶。一些电池汽车比汽油要节能97%。但是汽车工厂不能制造出持久耐用的电池。
燃料电池汽车：汽车制造者们如今正在学习以燃料电池作为能源去驾驶汽车。唯一不好方面他们会消耗干净的水资源。并且燃料电池更需高价制造。燃料电池耗费的金钱比汽油高上10倍。

Pb-Ac batteries是什么电池？
打得过

电池的话应该是一种那种飞腾电池，你可以去试一下。

一、镍镉电池（nickel-cadmiun batteries）的特性

　　1．镍镉电池可重复500次以上的充放电，非常的经济；
　　2．内阻小，可供大电流的放电，当它放电时电压的变化很小，作为直流电源是一种质量极佳的电池；
　　3．因为采用完全密封式，因此不会有电解液漏出的现象，也完全不需要补充电解液；
　　4．与其他种类电池相比之下，镍镉电池可耐过充电或放过电，操作简单方便；
　　5．长时间的放置下也不会使性能劣化，当十分充完电后即可恢复原来的特性；
　　6．可使用在很广的温度范围内；
　　7．因为它采用金属容器而作成，有机械性的坚固；
　　8．镍镉电池在非常严格的品质管理下被制造完成，有非常优良的品质性赖性。

　　二、镍镉电池放电特性

　　1．放电电压依据其放电电流多少有些差异，大体上是1.2v左右；
　　2．电池的容量以ah,mah的单位来表示；
　　3．当放电达到放电终了的极限时称之为"放电终止电压"，镍镉电池的放电终止电压为1.0v/cell；
　　4．使用温度范围在-20℃~60℃，在此范围内可进行放电。

　　三、保存上的注意事项

　　1．可在-30℃~50℃的温度范围之间内保存，但如果是长时间放置的情形下，请在35℃以下保存；
　　2．充电状态或者是放电状态的保存都是可能的，但是比较之下放电状态可使容量较早回复并且较易被激活；
　　3．当电池在长时间的放置后，使用前必须十分地充电后再使用。

　　四、镍镉电池的记忆效应（memory effect）

　　当镍镉电池重复经过几次维持在低容量的放充后，如果必须做一个较大量的放电时电池会无法作用，这种情形我们称为"记忆效应"。记忆效应可能是镍镉电池中最容易被误解的问题。放电终止电压被设定较高的录像机，随着使用的电压变低，表面上看起来似乎随着降低，但是放电电压的低下是可以由1～2次的完全放电而解决这一现象。建议十次充电后进行一次放电，以防止建议效应。
因此只要你按照上面的特性好好使用电池的话应该不会爆炸的。

兄弟不要拿神舟飞船和民用品相比。

别的不说，镍镉电池很重，不适合在电动车上用 会炸 只要充电时间过长

不会的，朋友

炸倒是不会。不过镍镉电池每次都要深充深放的，而且每次充电都要严格控制时间，比较麻烦，不如锂电方便。还有，你这充电器还是拿别的改装的啊，安全性恨难说，还是别这样了。你说的电动车电池爆炸好像应该是在钥匙或金属物体同时触碰正负极的时候才有可能发生的吧。

大意是此手表防水，一般时如何保持手表正常工作，换电池时的注意事项和保修问题

安卓上有一个扫图翻译软件，你下载之后就知道了，大概是说是防水手表，时间久了会坏，注意定期换电池。

　　防水的说明书，没啥重要的信息

就是说明防水性的，没什么实际意义

防水性 日常生活中完全防水抗50w气压防水因年份恶化换电池处理不当可能防水性恶化被水长时问在高压地区（如深海潜水）多半不可修理 剩下的你去查词典吧不过这个手表真心功能强大只要不是畜意破坏 活到寿中正*是没问题的！

Second, the direction of development of new energy vehicles

Two, the development direction of car of new energy have accurate definition of new energy vehicles, refers to the use of non conventional car as the power source for fuel (or the use of conventional fuels, the new vehicle power device), the integrated vehicle dynamic control and driving of advanced technology, technology advanced, has formed the new structure, new technology of automobile. New energy vehicles, including hybrid cars, pure electric vehicles (BEV, including solar cars), fuel cell electric vehicle (FCEV), hydrogen engine cars, other new energy sources (such as high energy storage, two ether) automobile etc.. The following describes the following: 1, hybrid electric vehicles hybrid electric vehicle with internal combustion engine and motor as power, because it is the power source, does not need to store large amounts of energy in the energy storage device, which overcomes the disadvantage of short driving distance of electric vehicles, and fuel economy is superior to conventional car. Save non renewable energy, and grea日夏养花网tly reduced exhaust emissions, is the mainstream of the electric car market at present. However, the two sets of system installed at the same time to just install a system on the car, not only increase the car's weight, also increased the overall process control requirements, etc.. Thus the structure of hybrid vehicle control complex, high technical requirements, the cost and the selling price of the corresponding higher. And it is still used in the traditional internal combustion engine, the consumption of non renewable energy resources can hardly be avoided, to improve energy utilization and Protect environment performance is still unsatisfactory. 2, the pure electric vehicles electric vehicle is an internal combustion engine to replace the motor fuel, using the motor as power, electrochemical battery as energy storage unit, with no dependence on oil, no noise and vibration, good performance, high efficiency advantages. Advantages of power is not used fuel, zero emission and low noise; at the same time, because of the use of electric energy control system compared with the single, hybrid electric vehicle is simplified, the cost is reduced, the price also can compensatRnLdDefxe the battery. However, energy density and powewww.rixia.ccr density electrochemical battery is relatively small, the endurance is low, the pure electric vehicles can only be used for tourism and other short-range travel. Although the recent development of the high performance battery such as a lithium ion battery has achieved great success, but its cost is higher, the further promotion of pure electric vehicle is very difficult. Figure 2 is a pure motor structure diagram. 3, the fuel cell electric vehicle fuel cell electric vehicles with electric motor as power, fuel battery as energy conversion device, use hydrogen as fuel. The development of fuel cell vehicle difficulty lies in hydrogen storage, fuel cell size and high cost of production, development of high performance of proton exchange membrane and complex control systems, electric vehicles powered by fuel cell powered fuel cell electric car called the FCE (Fuel Cell Electric Vehicle), FCEV is the first big the fuel cell bus FCEB (Fuel Cell Electric Bus). The quality of fuel cell early FCEV itself and its ancillary equipment of heavy, bulky, occupy the bus loading space very much, almost no passenger space, bring great difficulties to the general layout FCEV. Compared with the traditional internal combustion engine, F C E V not by thermomechanical process, not by the Kano cycle limit, has the advantages of high energy conversion efficiency, environmental friendly diesel vehicle incomparable, but can still keep the traditional internal combustion engine vehicle high speed, long distance running and safety, comfort, is considered the twenty-first Century clean first, efficient means of transport. Domestic and foreign experts generally believe that fuel cell technology will become the core of auto industry in twenty-first Century.
