摘　　要：本文利用Carleman估计和算子链方法,研究了一类初始曲线含重特征点的二阶退缩双曲型方程的柯西问题在分布类中的唯一性.The uniqueness, in the distrubutions, of solutions of the Cauchy problem for a class of degenerate hyperbolic second order equations is studied under the initial curve containing a doubly characteristic point. The techniques employed are Careleman estimates and concatenation methoed.
