一类n阶4－正则图的强协调性

STRONG HARMONICITY FOR SOME KIND OF 4-REGULAR GRAPH OF ORDER n

关于２－正则图、３－正则图的强协调性的研究已有结果．对于个正则图，已取得如下结果：ｎ阶４－正则图是强协调图的必要条件为．根据点、线的特定组合结构给也了当ｎ＝４ｓ（ｓ＞２）时，一类ｎ阶４－正则图的一个强协调标号．

The result of research about strong harmonicity of 2-regular and 3-regular graphshad been obtained and about 4-regular graph the result of research had been obtained as follows:If G is 4-regular strongly harmonious graph of order n then n0(mod 4).In this paper,according to specially designated combinatory constitution of vertices and edges,a united strongly harmonious lobeling for some kind of 4-regular graph df order 4s(s>2)is given.
