The main results are: 1. The horizontal wind speed fluctuations at any height may be approximated by a Gaussian distribution.

得到下面主要结果：(1)各个高度上水平风速模涨落的概率分布近于正态律。

At the same time, the dependence of the critical heights of pollutant and chimney on the height of hill, intensity of inversion and ground horizontal wind speed are shown.

同时，说明了污染物临界高度和烟囱临界高度对山体高度、逆温层强度和地面水平风速的依赖关系。

Besides, through test of sensitivity, the critical values of height of hill, intensity of inversion and horizontal wind speed, which have important influence on transfer of wind are obtained.

通过敏感性试验，发现了对气流输送有重要影响的逆温强度和山体高度及水平风速的关键值。
