| 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. |

| Keywords: | program slicing forward slicing backward slicing |
