Finally, the thesis analyzes statistical laws of the maximum saltating height and saltating length of saltating sand grains and they follow Gamma function distribution. This is consistent with the results of water-sand motion. It shows that statistical laws of saltating height and saltating length of saltating sand grains are independent of the medium of flow. It is possible the nature of saltating sand grains.

最后，分析了沙粒跃移距离、跃移高度的相对量的统计规律，认为它们均服从Gamma函数分布，与在含沙水流中的研究结果一致，说明沙粒跃移运动的跃移高度与跃移距离的统计规律与流场、所处的介质无关，这可能是沙粒跃移运动的本质所在。

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。

The results of calculations showed that the maximum increments in saltation height and horizontal distance due to the Magnus force were 10.2 and 24.9%, respectively, and that both increments increased with increasing lift-off angle. The maximum increments in saltation height and horizontal distance of sand grains caused by the Saffman force were only 4.6 and 3.7%, respectively. The vertical concentration distribution of Aeolian sand flow follows exponential function distribution whether or not force analysis of saltating sand grains includes Magnus and Saffman force. The effect of Magnus and Saffman force on the vertical concentration distribution of Aeolian sand current makes the rate decrease near sand bed and it is consistent with the effects of Magnus and Saffman force on the saltation height and distance of sand grains.

Magnus力对跃移高度和水平距离产生的最大增量分别可达到10.2%和24.9％，这两个增量均随起跃角度的增加而增大；Saffman力对跃移高度和水平跃移距离产生的最大增量分别为4.6%和3.7%；是否考虑Magnus与Saffman力，风沙流垂向质量百分浓度均服从指数函数分布，Magnus与Saffman力使得风沙流垂向质量百分浓度较不考虑它们的作用呈现出底层的比例较小，上层较大，Magnus与Saffman力对跃移高度的影响基本与其对风沙流垂向质量分布的影响一致，不过Magus力对风沙流垂向质量百分浓度分布影响较大，0-2cm范围内尤为强烈(7.16-10.81)，其他高度层(2-20 cm)的影响相对较小(0-2.95)。
