摘　　要：本文采用УсковВН[1] 所创立的微分动力学相容性条件 ,分析了锥形拉伐尔喷管在理想超音速射流情况下 ,射流中悬挂激波产生的问题 ,通过数学推导给出了其解析表达式。Studies the shock wave in a conical Laval nozzle using V.N Uskov's method of differential dynamics compatibility condition, in which the nozzle pressure ratio n is equal to 1. Through mathematical analysis, analytical solution of forming suspending shock wave is obtained for these conical Laval nozzles. The calculated results are shown in figures for different nozzles, one of which is compared with the results obtained from the characteristic method.
