Abstract: In this paper we get the three dimensions distribution map of the temperature field for the test chamber which can directly and expediently understand the specific distribution of the temperature field of environment test chamber,through in arranging some appropriate testing point in the environment temperature test chamber ,using interpolation and appropriate function fitting method and an infinite detailed three-dimensional matrix to simulate the temperature distribution of the test chamber based on the actual data collected of the testing point.This simulation and analysis only aimed at special section of the rectangle test chamber.

Key words: Spatial modeling, Numerical simulation, Three-dimensional matrix, Alculation and simulation of temperature field
