In order to facilely perform testing on C or C++ programs, a prototype tool called CppTest is designed and implemented. It can employ three levels'testing, namely (1) structural testing in method level by analyzing program's constructs, instrumenting probes, redirecting I/O stream, etc.,(2) state-based class level testing through modeling state transition behaviors using an extended finite state machine from the class specifications, and (3) system level black-box testing with some traditional strategies such as equivalence partitioning and boundary-value analysis.

以目前普遍使用的C/C++程序作为测试对象，实现了一个能进行方法级、类级和系统级三个级别测试的原型系统CppTest：基于程序CFG图分析、探针插装和I/O重定向等技术，实现方法级结构性测试；按照需求规约运用EFSM对类的状态转换行为进行建模，并依此自动生成测试用例集，实现基于状态的类测试；在系统级别上，运用等价类划分、边界值分析等常规策略进行黑盒测试。

Traditionally, a surface is usually scatted in an array of 3D data points which are topologically connected by rows and columns to form a rectangular mesh. This method can't meet the requirement of description and measurement for some complex surfaces. On the basis of tracing border points, a new method is proposed to deliver 3D data points of surfaces, which are topologically constructed with optimum rectangular and triangular mesh. In order to measure surface efficiently and safely with NC machine, an optimization of measurement paths is proposed to avoid interference between the measuring tool and the surface with holes. The curve design is the basis of surface modeling.

数控测量技术的发展为测量自动化、集成化、智能化提供了可能，而对于复杂曲面的自动测量规划则是测量技术中的难点问题，平行截面等数目测点分布和四边拓扑测点分布规划方法，不论在测点分布的合理性上还是在网格结构的优化方面，均难以满足形状或边界较复杂曲面的离散化描述和曲面造型的要求，为了实现任意拓扑曲面的自动测量，本文对复杂曲面的合理离散化描述和自动测量问题进行了研究，提出了基于边界跟踪、优化网格的测点自动分布规划和四边、三角混合网格的生成方法：同时对具有孔洞或测量干涉凸台等非完整曲面的测量路径优化问题进行了研究，提出了路径优化方法。
