Approach the mathematical problems constitution and problem posing;

On the basis of the regularization technique for dealing with ill-posed mathematical problems, the unknown clear image as well as the unknown point-spread function are incorporated in a single cost functional by constructing approp-tiate regularization terms.

How to solve the mathematical problems by use of mathematical model was illustrated.

Again research for solve mathematical problem by the physical methods;

Some mathematical problems from multivariables equations solved by Picard iteration such as convergence conditions,selection of iteration functions are explained.

In mathematics teaching,we should follow the expanding mode of thinking of “exceeding conventional rules, striving for variation”, grasp the “fluent, flexible, creative” characteristics of expanding thinking, choose the expanding point correctly, select mathematics problems carefully, foster the students’ abilities of expanding thinking by way of solving mathematics problems.

Posing mathematics problem-the departure point and foundation of initiative in the mathematics.

Through analyzing mathematic problems,constructing a system related to the problem to study constants and variables is helpful to connect individual variables with each other.

The paper presents five principles of transforming method in solving mathematic problems through some examples,which will be great value of students studying mathematic methods.
