So what we're saying here is the incident energy, so the energy coming in, is just equal to the minimum energy that's required to eject an electron.
这里我们来讨论一下,入射能量正好等于,发射出一个电子所需要的最低能量的情况。
So you can think of it, if we were to just think of it as a straight line that we were going across, essentially what we're saying is that we're getting from point a to point c without ever getting through point b.
你们可以来想想看,如我我们把它想成是一条直线,我们要沿着这条线经过,这就是说我们要从a点,不经过b点而到c点。
We're just saying we want What we're saying is, we know that the candidates aren't going to position themselves at 1 and aren't going to position themselves at 10.
我们只是想,我们要说的是,我们知道候选人,不会选择立场1,同样也不会选择立场10
So we're not saying it's all the electron density, it's just 90%.
因此我们并没有说所有的电子密度,而是百分之九十。
All right, so that's just solving out the algebra, so we're saying what q solves, a - c over 2b - q2 over 2 = 0.
没错,只需要解出当,/2b-q2/2=0,时q2的值即可
