关于二变元双曲型方程具有不完全Huygens现象的注记

Remark of incomplete huygens′s phenomenon for hyperbolic equation with two independent variables

本文给出二变元双曲型方程具有不完全Ｈｕｙｇｅｎｓ现象时，通解在任意四条特征线的交点处的相关性。

The relativitg of the general solution at intersection point of four characteristics is given in this paper when the hyperbolic equation with two independent variables, appears Huygens′s phenomenon.
