穿过此区的折射因低速而有延迟，又由于透射损失而有衰减。
Refractions which transit the zone will be delayed because of low velocity and attenuated because of transmission loss.
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.
