【编者按】我也(ye)曾经想过手机电池为什么越(yue)充越慢,甚至怀疑是不是自己心理作用(yong),越急就会觉得越慢。但实际上,看来是有(you)一定原因的。我们(men)来看看这方面的(de)英语说法。

【译】虽然(ran)电池现在从0充(chong)电到50只需要5到10分钟,但之后充到100%几乎需要两倍(bei)的时间。
【单词】nowadays ['nou-uh-deyz]['na??de?z] adv. 现今;现在,相当于“at this time”

【短语】more and more 越来越多的;例句:Now more and more people are streaming into big cities. 现在越来(lai)越多的人涌进大城市。
For explainational purposes phones are similar that it takes longer for the ions to find a place in the battery when charging when it is close to full.

First of all the energy % level is hard to actually measure for most batteries, and your phone estimates how full it really is.

【译】如何进行估算对这(zhe)一点有很大的影响。
【单词】estimation [es-tuh-'mey-shuhn][?est?'me??n] n. 判断;估计
Also the fuller a battery is the harder it gets to fill it further because less material to react is left, and the "force to decharge it" gets stronger.
【译】另外,电池越满,就越难再充满电池,因为剩下的反应物质就越少,“反充(chong)电的力量”就越强。
【单词】fill 动词原形 [fil][f?l] vt. 装满;弥漫;填充;担任
【单词】react 动词原形 [ree-'akt][ri'?kt] v. 反(fan)应;反攻
【单词】decharge ['det?ɑ?d?] 这里指使电池更难充进去电的力量

【译】但当电池(shi)接近它可以安全承载的最大(da)电压时,你可以用来迫使(shi)电流进入电池的电压比电(dian)池现在的电压仅仅高一点点(dian),因此电流流入它的速度会非常慢。
