摘要
首先给出了太阳图GS4,n和双圈图Um,n的定义,然后通过构造方法给出了太阳图GS4,n与双圈图Um,n(当m≡0(mod4)且n≡0(mod4)时)的奇优美标号,从而证明了太阳图与双圈图(当m≡0(mod4)且n≡0(mod4)时)都是奇优美图.
Gave the definitions of Sun-graph GS4,n and Double-circles graph Um,n. Discussed the odd graceful labeling of GS4,n and Um,n(when m≡0(mod4) and n≡0(mod4 ) and shown that GS4,n and Um,n(when m≡0(mod4) and n≡0(mod4)) are odd graceful.
