impossibility

Analysis to the impossibility of vocational education of medicine;

医学高职教育的不可行性分析

With the use of necessary condition,enoughcondition and their logical relation we will give the definition of the nonfeasible study.

在分析可行性研究的理论和实践中存在问题的基础上，利用数学中的充分条件、必要条件及充分必要条件等概念及它们之间的推理关系去抽象可行性研究的内容，给出“不可行性研究”的定义及其论证方法，以使项目的论证更准确、更可靠。

“Feasible thesis” has already been a normal rule when the decision of important projects is made, but the “infeasible thesis” hasn t been taken seriously.

重大项目决策前进行“可行性论证”已经成为一项常规制度,但“不可行性论证”却尚未引起必要的重视。
