摘要: 前向切片和后向切片是两种不同的切片技术,为了研究它们之间的异同,通过实验,得到两个结论:后向切片分析的平均缩减率等于前向切片分析的平均缩减率;后向切片分析的缩减率较均衡,前向切片分析的缩减率变化较大,极端情况较多。

Abstract: Forward slicing and backward slicing are two different slicing techniques.In order to understand the similarities and differences between the two slicing techniques,some experiments are done.Two results are got: one is that the average size of all static backward slices is the same as the average size of all static forward slices; the other is that the distributions of backward slices cluster averagely,while the distributions of forward slices cluster in the extreme.

Key words: program slicing, forward slicing, backward slicing
