这个失败很容易理解，但我不确定是不是真的要“修正”它——我没有测试的这个方法非常微不足道，为这么微不足道的方法添加测试有点浪费精力。

This failure is easy to understand, but I'm not sure I really want to "fix" it — the method I'm not testing is trivial, and adding tests for trivial methods can be a waste of effort.

Well, we can't guarantee with UV light we'll have enough energy to eject every single electron, so that's why when we use x-rays, they're higher energy, you can pretty much be guaranteed we're going to eject all of those electrons there.

好，我们不能保证紫外光有足够的能量,激发出每一个电子，所以我们要使用，X，射线，它的能量更高，你可以非常确定,我们可以激发出其中所有的电子。
