【编者按】我也曾经想过手机(ji)电池为什么越充越慢,甚至怀(huai)疑是不是自己心理(li)作用,越急就会觉(jue)得越慢。但实际上(shang),看来是有一定(ding)原因的。我们来看看这方面(mian)的英语说法。
Why does it take longer for mobile batteries to charge after 70-80%?

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.

【单词】estimation [es-tuh-'mey-shuhn][?est?'me??n] n. 判断;估(gu)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(dian)池越满,就越难再充满电池,因为(wei)剩下的反应物质就越少,“反充电的力量”就越强。
【单词】fill 动词原形 [fil][f?l] vt. 装满;弥漫;填充;担(dan)任
【单词(ci)】react 动词原形 [ree-'akt][ri'?kt] v. 反应;反攻
