摘　　要：文章主要论述椭球概率误差计算模型、方法及软件界面设计,介绍了软件实现结果。根据椭球概率误差的定义计算椭球概率误差,是基于解方程的方法实现的;需要得到椭球3个对称轴的数值关系,这是计算椭球概率误差的关键。计算软件是基于VC对话框的形式设计与实现的。文中通过一些实例利用数学工具软件Mathcad,分别计算椭球概率误差、球概率误差,比较了二者的差别,得到一些结论。文章利用Mathcad验证所编软件运行结果的正确性,是验证算法软件运行结果的较好途径。This paper mainly discusses the computational model and method and the software interface design for ellipsoid spherical error of probability.The paper calculates ellipsoid spherical error of probability basing on the definition for ellipsoid spherical error of probability.It implements basing on the method for solving equation.It needs to get the numerical relation of three symmetry axises of the ellipsoid spherical.This is the key to calcu-late ellipsoid spherical error of probability.The computational software is designed and implemented basing on visual C dialog box.It independently calculates the ellipsoid spherical and spherical error of probability.The results are compared and we reach a conclusion.This paper validates the correctness for the software running re-sult by Mathcad,and this is the better route to validate software arithmetic running result.
