Firstly, saltating sand grains in various height layers mostly rotate clockwise; the rate of counterclockwise rotation changes from 16.7 to 33.3% for three different friction wind speed (u*= 0.67, 0.83, and 0.87 m/s). However, their mean rotational speeds were not significantly different, irrespective of whether the grains rotated clockwise or counterclockwise. The mean counterclockwise rotational speeds of sand grains for friction wind speed u*= 0.67, 0.83, and 0.87 m/s were 427, 519, and 604 rev/s, versus 429, 522, and 609 rev/s, respectively, in the clockwise direction.

首先，风沙流中各高度层内跃移沙粒旋转均以顺时针方向为主，逆时针方向旋转的沙粒数仅占总数的16.7-29.5%，但是无论逆时针还是顺时针旋转的沙粒，它们的平均旋转速度几乎没有差别(如u*＝0.67 m/s时，分别为427 rev/s和429 rev/s；u*＝0.83 m/s，分别为519 rev/s和522 rev/s；u*＝0.87 m/s，分别为604 rev/s和609 rev/s)；不同摩阻风速条件下各高度层内沙粒的旋转速度均服从Lorentzian分布。
