Any graceful graph is the subgraph of another graceful graph

A kind of relationship between the grace and the graceful graph is studied which shows that any graceful graph can be embedded into another one.It is proved that if graph G1 is any graceful graph,there must be a graceful graph G2 such that G is a real subgraph of graph G2.Thus,a series of graceful graphs can be constructed from one graceful graph.And several kinds of graceful graphs are produced using this method.
