潜血印迹显现方法研究进展

潜血印迹一般出现在恶性刑事案件当中,能够反映与案件有关的多方面信息,对于同一认定和分析判断案情具有十分重要的作用,这就使得其显现成为现场勘查的一项必不可少的工作。然而,这也正是公安实践工作当中的难点所在。经过多年的实验研究,目前国内外针对于潜血印迹的显现方法主要包括光学显现法和化学显现法。综述了这些常用显现方法的研究进展,并且讨论了每种显现方法在实践工作当中的优势和不足。

The Progress of Latent Blood Prints Developing

Latent blood prints often appear in malignant criminal cases and can reflect useful information relevant to the cases. To develop latent blood prints is necessary in criminal scene investigation, which is of vital significance to identification and case analysis. However, it is also the difficulty of public security work. There exist optical and chemical methods of developing latent blood prints after years of experimental researches. The development of these methods was reviewed in this paper, and their advantages and deficiencies in the forensic practice were discussed.
