不同纸张上手印的茚二酮显现研究

目的:评价茚二酮对不同纸张上潜在手印的显现效果,以确定茚二酮法的应用前景。方法:针对茚二酮的特点设计实验方案,用具体的实验过程以及实验结果来论证茚二酮的显现效果。结果:茚二酮对30天以内的汗液手印的显出率能达到75%以上,对30天以内的纯鸡蛋白手印的显出率能达到95%。结论:茚二酮对于不同纸张上的汗液手印和蛋白质手印显现效果良好。

The research on developing Iatent fingerprints on different papers by useing indanedione method

Objetive: Appraise the latent fingreeprings developing effect on different papers by use indanedione,so we can be sure about the prospect of the indanedione method. Method:Accoding to the speciality of indanedione,We designed a expefiment to demonStrate developing effct of indanedione method by experiment course and experiment effct. Results:Indanedione can achieve more than 75% to the showing rate of fingerprint of sweat on paper within 30 days,and the showing rate to the fingerprint of egg albumen 30 days can be upto 95%. Conclusion:The developing effect is good that sweat fingerprint and the protein fingerprint on different paper is developed by indanedione,So indanedione methodpossesses the good appphcation foregound.
