摘    要:通过正交试验筛选出2%茚三酮与0.5%硝酸银/乙醇混合液分别对牛皮纸、硬纸板、A4复印纸三种客体表面上不同时期遗留的潜汗指印进行显现。结果表明该混合显现液均能显现渗透性和非渗透性客体上的新鲜指印,和不同时期的陈旧性潜汗指印。而且对陈旧性潜汗指印的显现效果与常见的显现方法的显现效果进行了对比,分析得出混合显现液在许多方面存在较多的优势。

关 键 词:茚三酮与硝酸银/乙醇混合液  潜汗指印  渗透性客体

Abstract:The mixture of 2% Ninhydrine and 0.5% silver nitrate/ethanol is fingerprint reagent which was selected by orthogonal test.The latent fingerprint is developed on the kraft paper,cardboard and A4 copy paper by this mixed reagent,The results showed that fresh fingerprint and old latent fingerprint of different periods are developed on the permeable and non-permeable object.For old latent fingerprint,the developing effect by this mixed reagent is more advantages than the common manifestation in many respects.
Keywords:Mixture of Ninhydrine and Silver nitrate/ethanol  Latent Fingerprints  Permeable Paper
