有向图的广义本原指数是本原有向图传统本原指数的推广，应用在非记忆通讯系统中。
( 3 ) we give an upper bound for lewin index , which is related to generalized primitive exponents of primitive digraph of order n and girth 2 , determine the index set of this class digraph and discuss the extreme cases
( 3 )第4节分析了围长为2的n阶本原有向图的l ( g )的上界及相应的指数集，并讨论了极端情形。
The main results are : ( 1 ) we give an upper bound for kth generalized primitive exponents of primitive digraphs with order n and girth 2 , and determine the exponent set of this class digraphs in section 2
