摘　　要：讨论了重特征方程Ｌ＿ｐｕ＝ｕ＿ｘｘ－ｘ￣２ｕ＿ｔｔ＋ｐｕ＿ｔ＝０的广义混合问题，即在曲线ｔ＝μ（ｘ）上给出初始条件。文中证明了对一切实数ｐ，广义混合问题的解都是存在唯一的。The generalized mixed problem in the multi-characteristic equation u_(xx)-x￣2u_(tt)+pu_t=0 is discussed with the initial value condition given based on the Curve t = μ(x).It has been proved that for all real value p,the generalized mixed problem has unique solution.
