提出了把波动效应分析和系统依赖图结合起来进行切片的方法，通过波动效应分析反映面向对象程序中单元间的波动关系，基于系统依赖图切片侧重于分析控制依赖和数据依赖。
This method can be used to analyze the semantic relations in object-oriented program units by ripple effect analysis, and the control dependency and data dependency by use of system dependency graph.
针对面向对象语言程序，提出了一种改进后的系统依赖图：ISDG，用来更好地表示面向对象程序中的依赖关系，从而解决了对象类型参数和属性的表示问题。
ISDG, an improved system dependence graph, is proposed in order to better describe relationships in object-oriented programs. ISDG solves the description problem of parameterized objects.
