该公司设计的太阳能电池板装有一种新型的半导体，这种半导体能捕获正电荷产生电能。
But the cost is positive, and a crucial first step to dealing with climate change, therefore, is to charge people for the carbon they emit.
但是，这种成本能带来积极影响，它是与气候变化作斗争的关键性起步，因此，向排放碳的个体收取费用有合理的理由。
The electrons carry the negative charge, the protons carry the positive charge. That was all that was needed.
电子携带负电荷，而质子携带正电荷，这就是所有需要的东西。

他将负责试图重新定位托克品牌正面的公众形象。
The oxygen atom has a slight negative charge while thehydrogen atoms share a compensating positive charge.
氧原子有轻微的负电荷，而氢原子则带对应的正电荷。
The only particles of positive charge known at that time were protons.
当时唯一知道的带有正电荷的粒子是质子。
So, if I've got positive charge uniformly distributed, look at the choice. It's a brilliant experiment.
所以如果按照正电荷是均匀分布的假设来说，就会是这样的，这是一个聪明的实验。
And remember that in a capacitor, negative charge builds on one side and positive charge builds on the other.
还有在电容中，也使正电荷在一侧，负电荷在另一侧。
