I have shown that by taking Avogadro's number of individual ion pairs and putting them all together in a line, the system's energy became more negative.

我推导出了,从每一个离子对中抽出阿伏加德罗常数,再把它们放在一起在一列中，这个系统的能量就变得更负。

Well, we would have to H+ have one of these hydrogen atoms go to an H plus, * plus an electron, right? **H --> H+ + e-** So, now we have a hydrogen ion here.

我们先要让,一个氢原子变成氢离子，加上一个电子，对么*,我们现在有一个氢离子了。

And all ion channels are selective for a single type of ion, and we can think about how that selectivity takes place, and that's where this idea of atomic radius is going to become very important.

所有的离子通道都是仅对某一种离子具有选择性的，而我们可以来想一想这种选择性是如何发生的，这也就是原子半径这个概念将会变得，非常重要的地方。

This conversion from a mechanical energy into a chemical energy can be nicely visualized when one fills a hair cell with a sensitive die that responds to the calcium ions that influx into the cell.

如果在毛细胞中注入,对钙离子敏感的物质,可以精确地模拟,这一机械能到化学能的转化过程。

And they remain two atoms per ion pair discretely bombing around in the gas phase.

每个离子对中仍含有两个院子,分散得分布于气相中。

When you add this whole thing up, -411kJ/mol it gives you a net of minus 411 kilojoules per mole or about 4 eV per ion pair.

当你全部加上时，得到净能量,或者是4eV每个离子对。
