%X By means of the basic vectors matched for group chain ((O?D_3?C_3)×SU(2))~N, the Slater functions of the direct product for single electron can be used as the basis vectors of the irreducible representations of d~N ions or the direct summa-tion representations of two one-dimensional representation. The matrix element ex-pressions related and the calculation of EPR parameters are systematically derived and the corresponding computer programs for all d~N ion in trigonal field have been compiled.
