摘要
本文讨论了阻尼网对迎面自由射流的作用过程，在射流宽度及阻尼网的压差系数ｋ都不大的假设下，导出了对应的微分方程，用小参数方法求得该方程的解，并讨论了阻尼网对自由射流的作用．
In this article,we discussed the acting process of wire gauze to free jet. Supposed jet wide and pressure coefficient k of free jet were very small, the differential equations are deduced and their analytical solutions are obtained by thes the small Parameter method.
