So most of you recognize, if we switch back to the notes, that they do have a negative electron affinity.
看来大部人都想到了，如果你翻翻讲义的话，它们的电子亲和能确实是负的。
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？
With the merits of high hardness, high thermal conduction, negative electron affinity, diamond is deemed one of the preferred materials of the field emission cathode.
金刚石因具有高硬度、高热导率、负电子亲和势等优点而成为场发射阴极的首选材料之一。
So this is not going to be a favorable process, we're going to find that the electron affinity is actually a negative 7 kilojoules per mole for nitrogen.
因此这并不是一个容易发生的过程，我们会发现氮的电子亲和能，应该是负的，7，千焦每摩尔。
The formation of negative ions from these elements is difficult dut to electron affinity of these negative ions is near to or less than zero.
这些负离子对应元素的电子亲合势大部分接近或小于零，负离子难以形成。
The formation of negative ions from these elements is difficult dut to electron affinity of these negative ions is near to or less than zero.
这些负离子对应元素的电子亲合势大部分接近或小于零，负离子难以形成。
