And what we have left over is this amount of energy here, which is going to be the kinetic energy of the ejected electron.

都用来发射它，剩下的这些就是，出射电子的动能。

All right. We've got a big majority, and both are logical ways of thinking, but it turns out that the majority is correct, which is not always the case, but the electron is not ejected in this case.

好，大多数人都这么认为，这两种看法都是合乎逻辑的，但结果是大多数人是对的，这种情况不经常发生，但是电子在这种情况下，确实不会被逐出。

youdao

So in this case, we don't have enough energy to eject an electron, so, an electron is not ejected.

所以在这种情况下，我们没有足够的能量，去逐出一个电子，这样没有电子被逐出。

So in this case, we don't have enough energy to eject an electron, so, an electron is not ejected.

所以在这种情况下，我们没有足够的能量,去逐出一个电子，这样没有电子被逐出。

That is to say an electron has been ejected.

也就是说电子被移除了。

The second piece of information we need to know is what actually the kinetic energy is of the ejected electron, and that's something we can just measure by measuring its velocity.

其次，我们需要知道的信息是,出射电子的动能，这可以通过,测量它们的速度得到。
