哈： 你不会说，一名医生有资格相信他的病人患病是由于邪恶的眼睛，或者是伏都教，你不会说，弗朗西斯.柯林斯可以自由选择否认疾病微生物理论，你认可他在隔离世界的环境中尽心他的科研，这是个智力的问题。

You wouldn't say Francis Collins is free to deny the germ theory of disease. You're recommending he practises his science in a walled garden.

OK, elements with low average valence electron energy, and here I'm saying below 11 electron volts, these are good electron donors.

平均价电子能都较低的元素，我是指那些低于11电子伏的，这些是很好的电子给体。

Its average valence electron energy is 5.2 electron volts, which is a heck of a lot less than 11.

它的平均价电子能是,5。2电子伏，那比11电子伏要少得多。

And let's look at the final kinetic energy that we'd observe in this spectrum, which is 384 electron volts, so what is that third corresponding ionization energy?

然后让我们来看一下,在光谱中观测到的，最后一种动能，它大小是，384，电子伏，那么这相应的第三种电离能是多大？
