以可拓学理论为基础，论述了可拓检测的有关定义和概念，提出了可拓检测的方案生成方法及过程，同时探讨了检测方法的优化和评价方法。

This work shows a method to obtain an available scheme for extension detecting technology. Based on the theory of extenics, some definitions and conceptions about extension detecting are described in this paper. At the same time, the procedures of optimization and evaluation are explored in order to get the better scheme.
