The results show that not only the porosity does greatly affect the windbreak, but also the tree distance does. The distance is not beyond 1.3 to avoid air leak. The tree belt with porosity 31% has bigger windbreak range and better characteristics for abating wind erosion. The tight nubby tree belt is advised to restrain the particles adhering on the leaves refloating for large velocity deficit in trees.

结果表明：不仅林冠疏透度对防护林带的遮蔽防风有明显影响，而且树木间的株距对林带整体的遮蔽效果也有比较显著的影响，为避免穿流风对遮蔽效应的影响，林带宽距比不宜超过1.3；疏透度为31%的网状林带的有效防护范围大，防风效果好而且水土保持性强；紧密型块状林带，林后速度衰减幅度大，可抑制附着在叶片上粉尘的再次扬尘。

It can simulate charging testmethod, corona charging decay testmethod and triboelectric testmethod. In the part of signal receiver, signals which p resented the electrostatic potential of detected objects were collected by non2contact direct induction type electrostatic sensor. It utilized the capability of counting time of single chip computer to measure p recise electrostatic charge decay time in coordinate with the p rogram designed by C51 language.
