摘要
现场中的灰尘鞋印往往所含灰尘介质量比较少、与承痕客体背景之间反差不大。因此,对现场灰尘鞋印的增强显现是十分重要的。化学增强显现后的鞋印可以提供更多的鞋底花纹细节特征,使得技术人员可以进行更加全面、准确地检验。目前,灰尘鞋印国内外常用的化学增强技术有溴酚绿和溴酚蓝混合溶液增强技术、抗坏血酸与2,2'联吡啶增强灰尘足迹显现技术、荧光钙血迹蓝钠试剂显现灰尘足迹、硫氰酸钾和硫氰酸铵显现法、8-羟基喹啉法、赤血盐显色法、物理显现液法及其DFO显现法。本文总结了利用化学试剂增强显现灰尘鞋印的技术方法,并对其未来的发展方向进行展望。
The dust shoeprints in the field often contain less dust medium quality and little contrast with the object background of the mark.Therefore,it is very important to enhance the appearance of dust shoe prints in the field.The chemically enhanced print can provide more detailed features of the sole pattern,allowing technicians to conduct a more comprehensive and accurate inspection.At present,the dust were commonly used chemical enhancement technique at home and abroad have bromophenol green and bromophenol blue mixture enhancement technique,ascorbic acid and 2,2'pyridine reinforced dust footprint appeared technology appeared,the fluorescent calcium in blood sodium reagent dust footprint appeared,potassium thiocyanate and ammonium thiocyanate,8-hydroxyquinoline,red blood liquid salt appeared chromogenic method,physical method and DFO method.In this paper,the technical methods of enhancing dust shoe prints by chemical reagents are summarized,and the future development direction is prospected.
