非对角解
1.
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.
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。
2) diagonal-non-negative matrix factorization
对角非负矩阵分解
