摘    要:刑事案件现场经常遗留一些具有一定渗透性的客体,如丝绸、橡胶、皮革等,上面留有汗液指纹。由于汗液的挥发性和客体的渗透性,部分的汗液挥发到空气中或是渗透到客体中,无色的汗液手印很难用肉眼观察到,因此难以进行直接拍照。利用汗液手印的化学特性,用加氨水催化法配合常用的502胶熏显法,可以较好地显现出手印并加以拍照,为物证鉴定提供依据。

关 键 词:渗透性客体  汗液手印  氨水催化法  502胶熏显  近距离照相

Abstract:There are often some permeable objects such as silk,rubber and leather left in the scene of crime. The sweat fingerprint left on them can not be photographed directly because it cannot be seen by naked eyes due to sweat's volatilization and object's permeability. Considering the chemical characteristics of sweat fingerprints,we can use catalytic method of ammonia injection combing with 502 glue smoke revealing method to reveal the fingerprints and take the pictures,therefore providing reference for material...
Keywords:permeable object  sweat fingerprint  catalytic method of ammonia injection  502 glce smoke revealing method  close photography
