In this paper, general expressions for transformation coefficients between the symmetry basis and physical basis of di-hadron system under two representations used commonly (which are called L.S and jj representations) have been given.

• 本文给出了两种常用表象(作者称之为L·S表象与jj表象)下双强子系统物理基与对称基之间变换系数的一般表达式.；对前者是两个SU_(mn)(?)
