摘　　要：得到了１５顶角模型Ａ２（１）模型和超对称ｔ－Ｊ模型反射方程的非对角解，结果发现，Ａ２（１）模型具有三种形式的非对角解，超对称ｔ－Ｊ模型具有一种形式的非对角解，每种形式的非对角解均含有两个解，每个非对角解中均含有三个任意参数．关于对角解也得到了一些新的形式的解．The non-diagonal solutions to the reflection equation of 15 vertex model A_2^(1) model and supersymmetric t-J model were obtained. The results show that solutions of A_2^(1) model' have three forms and each form contains two solutions; the solution of supersymmetric t-J model' takes only one form in which there are two solutions; each one of all those nondiagonal solutions only have three arbitr ary parameters.
