This paper utilizes DSSW model to discuss the change of returns of the noise traders in the condition of “mouse storehouse”, and puts forward corresponding enlightenments.

Second,it summa- rized the basic model of noise transactions theory-DSSW model particularly established an improved model.

Comparing initial model with revised model and expanded model, we found that the results based on initial model are quite different from the actual conditions, while the results based on revised model and expanded model fit the actual cond.

The FEM program is proven to be effective, and the Cosserat expanded model which complements the parameter equivalent method is one of effective methods for solving interlayered rock mass question.

Research of Data Mining Based on Concept Lattice and Its Extended Models;

Then it describes the extended model of the fuzzy cognitive map and ma.

In this paper we mainly study the isomorphic stabilization of spreading models of Orlicz sequence spaces.

The thesis mainly study the structure of countable spreading models of an Orlicz sequence space.

In recent years,the advent of the theory on spreading models not only provides a new way of thinking and methods for understanding and solving the above problems,but also has important meaning in the operator\'s existence and distortion of Banach space.
