【摘要】 DFO显现法和IDO显现法,都是显现纸张等渗透性客体上的汗液手印的有效方法。但是,实验研究发现,复印纸、白信封纸、报纸和牛皮纸上的汗液手印,用IDO法显现效果都优于DFO法。IDO法不仅手印的显现率高,而且显出的手印纹线更加清晰,可鉴定率也明显高于DFO法。更多还原

【Abstract】 Both DFO and IDO are the effective methods of developing potential fingerprints on the permeable objectsl.This experiment compared the effects of developing sweat fingerprints on A4 manifold paper,white envelope,newspaper and kraft paper with DFO and IDO reagents.We find that IDO is a better chemical reagent than DFO to develop potential fingerprints on the permeable objects.The lines of developed fingerprints are clear and the identified proportion of developed fingerprints with IDO is higher.更多还原
