摘　　要：由于阻抗的存在,阻抗式调压室不能完全反射水击波,存在水击穿室问题.本文根据阻抗式调压室的实际边界情况,利用水击基本方程,运用特征线法,通过对实例的计算分析,得出了管道长度对阻抗式调压室水击穿室系数的影响关系.Because of the exist of resistance in the chamber, transient water hammer wave can not suddenly expand, as a result, portion of it will enter into low pressure tunnel. Based on the boundary conditions and fundamental equations of water hammer wave, used characteristic method, calculated and analyzed a actual example. In this paper, a kind of relationship between the length of the tunnel and the coefficient of pressure transmission was involved such a problem.
