广东雨水多,气候较潮湿,刑侦勘查现场提取潜在手印,经常遇到各种潮湿客体,在一些侵犯人身权利的案件中,还常遇到粘性非渗透性客体(主要以胶带居多),需要提取案犯可能留下的手印。但用常规方法提取常常效果都不理想,甚至无法显现和提取,针对这问题我们探索了用荧光微粒悬浮液来显现提取潮湿或粘性物体表面潜在手印,实验表明荧光微粒悬浮液对潮湿客体和各种胶带(黄色或透明普通胶带、各种常见电工胶带、贴纸粘面等)有特别的显现效果,可以弥补粘性客体手印显现的某些不足。
Guangdong has a lot of rain and a relatively humid climate. Potential fingerprinting is extracted on the spot of criminal investigation, often encountering various damp objects. In some cases of infringement of personal rights, sticky non-permeable objects (mostly tapes) are often encountered and need to be extracted Handprint likely to be left by the perpetrator. However, the conventional methods are not ideal for the extraction or extraction. In view of this problem, we have explored the potential of fingerprints for the extraction of wet or sticky objects with fluorescent microparticle suspensions. Experiments show that the effect of the fluorescent microparticle suspension on wet objects and each Species of tape (yellow or transparent ordinary tape, all kinds of common electrical tape, stickers, etc.) have a special appearance, you can make up some of the viscous guest fingerprints revealed.
