摘要
用波动方程的函数不变解方法对具有任意自相似指数的空间轴对称弹性动力学问题求得了一般解。用本文方法可以迅速将所论问题化的Ｒｉｅｍａｎｎ—Ｈｉｆｂｅｒｔ问题或Ｋｅｌｄｙｓｈ－Ｓｅｄｏｖ混合问题．并可以相当简单地得到问题的闭合解、作为实例，文中对若干问题进行了求解．
on the basis of functionally-invariant of the wave eqation, the general representation of the solution is derived for axially symmems of elastic dinamic of arbitrary index of self-similarity. The problems of riemann-Hilbert or of Keldysh-sedov can be formulated immediately and the analytical solution was obtained with this method. Some problems ware analyzed as examples.
