针对试验方案评价中指标众多、权重难以确定等问题，引入密切值的评价方法；分析密切值方法的数学原理、处理步骤；给出试验方案密切值评价方法的应用案例；基于VC环境和MFC类库，对密切值评价方法进行软件实现，软件运行稳定，所得结果与理论分析吻合。%In test project evaluation, the evaluation factor is various and defining the factor weight is difficulty. In order to solve the problem, osculating value method is used. The math element and solution process are analyzed. The application example is put forward. The software of osculating value method is realized based on VC and MFC. The software runs steadily and the computed data is accord with theory analysis.
