Movement trajectories of electrons under complex field and state parameters when electrons return to the dielectric surface are obtained by simulation,such as impact energy and return time. Variation laws of electron movement with emergence angle and microwave electromagnetic parameters are also derived. The emergence angle of electron has significant effect on the movement of electron,and there is an emergence angle in which the electron has the maximum trajectory length and impact energy.

研究发现：电子出射角度对其运动状态有显著影响，电子存在运动轨迹最大的某一出射角度，该角度下电子拥有最大的撞击能量；微波电场幅值的增加将使电子撞击能量增加，返回时间减小，微波电场相位的变化使电子的撞击能量和返回时间呈周期振荡，这从本质上解释了电子数量在二次电子倍增过程中以微波频率两倍周期振荡的原因；随着微波频率的增加电子将由简单的类抛物线运动转变为复杂的振荡运动。

If its energy is larger, it may impart energy to atomic electrons as described by the Bohr theory, causing excitation of electrons to higher energy states or producing ionization, with subsequent emission of light.

果其能量更大，它可以按照波尔理论把能量传递给原子的电子，使电子激发到高能态或电离，并伴随发光现象。

"Photocell: or photoelectric cell, or electric eye; Solid-state device with a photosensitive cathode that emits electrons when illuminate d and an anode for collecting the emitted electrons."

光电管：一种固体探测器，有一个对光灵敏的阴极，受到光照时能发射电子，还有一个用于收集所发射电子的阳极。

Similarly, the number of negatively charged electrons moving around the nuclei of the atoms increases across a period, but the additional electrons are all located in the same electron energy level or shell.

在一个周期里，原子的核电荷数和核外电子数递增，但是另外的电子都排布在同一电子能级或电子层中。

The electrons are accelerated in the diffusion region near the X point, and the acceleration process can be roughly into two steps : firstly the electrons are accelerated in the z direction due to the electric field, then, they gyrate surrounding the magnetic field with the action of the Lorentz force and get higher velocity in the x direction.

电子在X点附近扩散区中被加速，且加速过程分为两步：先由z方向电场加速，进而在Lorentz力作用下，使其绕磁场回旋并在x方向获得高速度。

This characteristic could be qualitatively explained as interference between σ amplitude and π amplitude of electrons final wavefunction. It also depends on the impact parameters: the π amplitude contribution is dominant at small impact parameters, which leads to a symmetric velocity distribution around the internuclear axis. However, At large impact parameters the σ amplitude contribution increases relatively, resulting into a asymmetric electrons velocity distribution around the internuclear axis.

出射电子的上述分布特征可由出射电子波函数σ振幅和π振幅的干涉进行定性解释，σ振幅和π振幅对出射电子波函数的贡献与碰撞参数相关，在小碰撞参数下，π振幅的贡献更加明显；而在大碰撞参数下，σ振幅的贡献更加显著。
