In this paper, we define a class of new graph-spoon star graph and as wellas weak odd strong harmony graph, is defined, the writers give Stn P1C4’s odd graceful labeling、k- graceful labeling and weak odd strong harmony labeling,and prove that the Stn P1C4 is a odd graceful graph, k-graceful graph and weak odd strong harmony graph.
该文定义了一类新的图形——星勺图StnP1C4,并定义了图的次奇强协调性,同时给出了它的奇优美标号、k-优美标号及次奇强协调标号,从而证明了星勺图StnP1C4是奇优美图、k-优美图和次奇强协调图。

In this paper,we obtain three kinds of graphs by adding some vertices and some edges on,and proved that the three kinds of graphs not only are allgraceful,odd graceful,but also are balanced graphs and alternating graphs.
本文通过在上增加一些顶点和边,得到了三种图,并得出此三种图均是优美的,奇优美的,也是交错图,平衡图,同时给出了相应的标号。

It is shown that∪ni=1 Pli, ∪ni=1 Sli, ∪ni=1 Sli ∪∪ti=1 Pmi ,Cm ∪Pn and Cm ∪Cn are odd graceful, and that ∪ni=1 Cmi is odd graceful when mi ≡0(mod4).
讨论了并图∪ni=1Pli,∪ni=1Sli,∪in=1Sli∪∪it=1PmiCm∪Pn, Cm∪Cn和∪in=1Cmi,∪in=1Pli,∪in=1Sli,∪in=1Sli∪∪it=1PmiCm∪Pn, Cm∪Cn被证明了是奇优美的,∪in=1Cmi当mi≡0(mod4)时是奇优美的。
补充资料：麦美奇岩
一种超基性浅成岩或喷出岩。首次发现于俄罗斯西伯利亚地台迈麦恰河流域，故名。岩石由斑晶和基质两部分组成。斑晶为蛇纹石化橄榄石,粒度可达2～15毫米。按结晶程度，基质可分为玻璃、微晶和粒状三种，基质矿物为钛普通辉石、金属矿物以及杏仁状碳酸盐和蛇纹石填充物。当橄榄石达到一定含量时岩石相当于玻基纯橄岩。麦美奇岩常与苦橄岩、橄榄岩伴生。西伯利亚地台麦美奇岩的化学成分为（%）：SiO235.38,TiO21.41, Al2O32.73，Fe2O36.91，FeO6.06，MgO31.82，CaO5.99,Na2O0.27,K2O0.09, H2O9.06。当岩石中碱质偏高时则过渡为碱超基性岩。麦美奇岩常见于浅成岩体中。岩体上部和边部岩石多具脱玻和斑状结构，中部玻璃基质减少，下部变为粒状结构并逐渐过渡为橄榄岩。
