We define g(G) as the g function value of finite group G,it represents the number of isomorphic classes that groups with the same order type to G.

In the second part of this paper,we characterize some generalized metric spaces in terms of weak g-functions,weak base g-functions and w-structrues respectively.

In this paper,we give characterizations of strongle zero-dimensional metrizable spaces, metrizable spaces and some generalized metric spaces in terms of g-functions orω-structures.

By investigating and summarizing the classical Nolte G-function method and studying the special features of fractures in the fractured formation, the pressure decline curve analysis model for the fractured reservoir was developed.
