1) wind speed for sand moving
起沙风速
1.
The paper studies on wind speed for sand moving and sandstorm process in the desert by observation of volumes of sandstorm deposition in different positions and different parts.
纵穿沙漠长距离明渠会遇到强烈的风沙淤积,本文通过对起沙风速、沙漠风沙过程、不同地段和位置的风沙积沙量观测与研究,经分析论证,得出各风速风向下的渠道淤沙量,为防风机械固沙和生态固沙提出了科学的研究成果。
2) wind initiation of particles
风沙起动
3) Dust emission by wind erosion
风蚀起沙
4) threshold wind of transporting sand
起沙风
1.
The results showed that: (1)The threshold wind of transporting sand in the study area between March to May were most frequent, with an accumulated frequency of 38%～58%.
结果表明:①研究区3～5月起沙风发生频数最高,占全年起沙风的38%～58%;平均风速和最大风速值最大,分别为6。
5) Blown sand electrification
风沙起电
1.
Blown sand electrification intensify becomes large with increase of wind velocity and weak with enlargement of sand particle size.
利用国内大型风沙物理风洞实验模拟沙尘暴电现象 ,研究风沙起电机理 ,结果表明 ,不同风速下不同沙粒会产生不同极性的电场强度和电位效应 ,风沙电随风速增大而增强 ,且随沙粒度增大而减小 。
6) Effective wind regime
