In this paper,characters of geometrical figures are studied, and the solution methods and techniques for the problems of geometrical figures are proposed.

This paper expounds the close relationship between mathematical thought and physics teaching by describing some of the mathematical methods into the use of physics teaching and physics examination such as mathematical function thought,method of problems solving with geometric figures,method of mathematical extremum,mathematical induction as well as differential element method.

On Kant,Husserl and Wittgenstein s Approaches to the Philosophical Thought of Geometric Figure;

Finally the paper shows the realization of algorithm by vc++ language,which can recognise the regular geometric figure in the computer using this program.

This paper defines fuzzy sets, researches some problems of fuzzy mathematic and discusses the subjects of geometric figure with the concept of convex sets.

The problems of optimization and optimal geometrical figure of the resection are discussed in the paper, moreover, a practical and simple method for determining the reliable point position is given.

The E_R Model of Characteristic Parameter Library for One Class of Part was given and general methods for programming searching system and parametric geometry graphics were analyzed.

Finally,the five expressional types of the engineering and technieal language are discussed,including literal expression,plain geometric graph,stereo graph, object.
