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。

School of Ocean and Earth Science, Tongji University, Shanghai 210092, ChinaAbstract Sand dunes and gobies are easily seen and the near surface geological condition is very complex in Rubal-Khali basin, Saudi Arabia. Because of this, the horizontal velocity is quite unstable, making the static correction a hard problem. The original near surface model can not obtain a satisfactory solution for the statics problem due to the limited uphole survey and poor exploration status.
