摘　　要：给出了等价电子的正则杨盘的投影函数为Slater函数,给出了杨盘的置换算符对Slater函数的运算规则.由杨盘基的归一化将杨盘的杨算符区分为消去算符和有效置换算符,进而给出了正交归一化杨盘基的置换算符构造规则.这些极大的简化了杨盘置换算符的个数,给出了确定等价电子杨盘基的新杨盘方法.In this paper, the projection function of regular Young tableau of equivalent-electrons is proved to be a Slater function, and the operation rules of Young＇ s permutation operators operating on the Slater function are given. The Young operators can be distinguished as elimination operator and effective permutation operator by the normalization of Young basis, then the constructive rules of permutation operators of the orthogonal normalization of Young basis is given. By this method, the number of Young＇s permutation operators is reduced and the new Young tableau method of obtaining equivalent-electron Young basis is represented.
