摘要
工具痕迹在现场出现率高,但对其利用率很低。人的主观因素和技术上的客观因素是造成工具痕迹利用率低的主要原因,技术上的客观因素从根本上制约了对现场工具痕迹的利用。要着重剖析工具痕迹检验的技术上原因,深入了解工具痕迹检验技术的现状以及工具痕迹检验技术的国内外研究情况,并分析研究中所存在的问题,从而探寻工具痕迹检验技术的发展和研究方向。
The presence ratio of tool marks is high,however,its utilized ratio is low.The main reason of the low utilized ratio for tool marks is the subjective factor of person and the objective factor of technology which basically constraints the use of the tool marks.Firstly,the test actuality of tool marks is described.Then,the domestic and inteinational research instances are discussed and the existing problems of the research are pointed out.Finally,future directions of development and research for tool mark test technology are presented.
