Calculation programs of 2D, 2. 5D and 3D magnet field under all kinds of landspace and a set of transiting system of potential field on plane and section are trans-planted and optimized. Some applying software for backward evaluating magnetic pa-rameters directly are transplanted and developed. And the method of software testing is designed. The authors of this paper introduce method and technical key of model database workbench for good dialog between man and computer and Chinese Windows interface using...
