摘　　要：运用分析法研究了直积图的邻点可区别E-全染色,讨论了对于点色数至少为2以及邻点可区别E-全色数为3,4的简单图的直积图的邻点可区别E-全色数,并得出了一些相关推论。By using of the analysis method,the adjacent vertex distinguishing E-total coloring of the cartesian product graphs are studied,and the adjacent vertex distinguishing E-total chromatic numbers for the cartesian products of the graphs with chromatic number at least 2 or the graphs with adjacent vertex distinguishing E-total chromatic numbers 3 or4 are discussed,some relevant conclusions are also obtained.

关 键 词：直积图 邻点可区别E-全染色 邻点可区别E-全色数 色数
