摘　　要：利用局部非减压缩函数6取代通常的非减压缩函数6,并除去附加限制条件lim(t-Φ(t))=∞,获得了一类压缩映射的不动点定理。In this paper, we obtained some fixed point theorems for a class of contractive mappings in which the usual increasing contractive function. Ф is replaced by local increasing contracive function Ф and the usual additional restrictive condition. lim(t--Ф(t))=∞ is not required either.
