为了及时准确检验以橡胶为代表的高弹性客体上的工具痕迹,实验研究了衬垫物有缺陷时砍切橡胶痕迹的特点及变化规律,结果表明即使刀具本身没有特征,衬垫物有缺陷时,也会产生痕迹特征,其反映形象与工具特征留痕相似,但衬垫物缺陷会引起痕迹止缘形态奇变,根据这种奇变可以区分是工具特征留痕,还是衬垫物缺陷留痕,由此可准确识别刀具个别特征,并做出鉴定结论。
In order to accurately and accurately inspect the tool traces on the highly elastic object represented by rubber, the characteristics and variation of cutting rubber traces when the liner is defective are studied experimentally. The results show that even if the tool itself has no characteristic and the liner has defects , But also produce trace features, which reflect the image and tool features left traces similar, but the liner defects will cause traces of the odd changes in the shape of the rim, according to this strange change can be distinguished tool marks left, or liner defects Marks, which can accurately identify the individual characteristics of the tool, and make identification conclusion.
