The results show that, during the period of collision between the sand grain and the sand bed, the lost kinetic energy is more than half of the total energy. Moreover, because the percentage of collision angles with more than 0° is up to 70％, the vertical speed of sand increases even if the kinetic energy decreases, which ensures that the sand particles can receive more energy from the air to keep on the saltation movement.

实验结果表明，沙粒与沙床碰撞过程中损失的动能超过总能量的一半，且由于碰撞平面角大于0°的比例达到70％，即使沙粒在碰撞过程中能量有所损失，沙粒与沙床碰撞后垂直分速度增加的现象仍比较普遍，使得沙粒在与气流相互作用的过程中获取更多的能量，从而为沙粒的持续跃移提供了保证。
