陷阱的电荷捕获\释放机制在闪络发展过程中起着重要的作用，它与二次电子发射机制一起共同作用于真空中介质的沿面闪络发展过程中。

we start high and go low, we're dealing with emission where we have excess energy that the electron's giving off, and that energy is going to be equal the energy of the photon that is released and, of course, through our equations we know how to get from energy to frequency or to wavelength of the photon.
当我们从高到低时，我们说的,是发射,电子有多余的能量给出，这个能量等于，发出,光子的能量，当然我们可以通过方程,从能量知道，光子的频率，和波长。
