通过选择合适的初始入射角，使从平板前后表面反射的两光束实现剪切干涉。
The choice of proper initial Angle of incidence makes a lateral shearing interference easy to realize between the two beams reflected from the front and back surfaces of a plane-parallel plate.
计算结果表明：低速重离子的能量损失随初始电荷态的升高而缓慢上升，却随入射角度的增加而缓慢下降，离子的电荷态和入射角度对离子的掠角散射轨迹和能量损失都有影响。
It is observed that the energy losses decrease slowly with the increasing incident angles for low velocity ions, whereas swift ions lose more energy with the increase of the incident angles.
