Finally, the results of selecting the optimum exposure dose for two kinds of electron positive resists and the photos of LSI masks fabricated by this method are given.

最后，给出了用本法对两种正性电子抗蚀剂选择最佳曝光剂量的结果和制作的大规模集成电路掩模版的照片。

It is a naked electron and is a sodium positive ion.

它是个裸电子，是钠正离子。

Electron affinity, however, can be either negative or it can be positive.

但是，电子亲和能既可以是负的，也可以是正的。

So, for example, for the chlorine case, we would say that the electron affinity for chlorine is actually positive 349 kilojoules per mole.

比如，以氯为例，我们可以说氯的电子亲和能,应该等于正的，349，千焦每摩尔。

So do you think noble gases would have a high positive electron affinity, a low positive, or negative electron affinity?

那么，你认为稀有气体的电子亲和能,应该是一个高的正值，一个低的正值，还是一个负值？

For example, the positive ions, these are electron deficient.

例如，正离子，是缺少电子的。
