结果表明：近地表0.1m处收集到的沙尘物质主要来自于近地表跃移的沙粒，随着高度的增加，降尘中细沙成分越来越少，粉沙成分越来越大。

The results are as follows : the falling sand-dust of 0.1 m height near surface is mainly from saltation matter , the fine sand compositions of falling dust are fewer and the powder sand elements are more .

本课题研究的《浑水水力分离清水装置》可以从高含沙浓度的浑水中将水沙（包括0.01mm以下的极细沙和粘粒）分离，并获取清水。
