摘　　要：研究了两个围长为2的本原定号有向图,通过对图形的分析,综合运用本原指数,SSSD途径对,Frobenius指数的结论和特性,推导出了这两个图形的广义基.In this paper the local base of two class primitive signed digraphs with girth 2 was studied. The local base of the two digraphs were derived using the primitive digraph analysis associated with SSSD walks and Frobenius .
