| 摘 要： | 目的建立应用二氧化钛的小微粒悬浮液来显现潜在手印的方法。方法选择6种不同客体,分别取普通汗和皮脂汗手印各40枚,各保存1天和7天,用二氧化钛小微粒悬浮液进行手印显现。结果保存1天和7天的汗潜手印显现结果没有很大区别,但皮脂汗手印显现效果好于普通汗手印。结论二氧化钛的小微粒悬浮液可以有效地显现出光滑非渗透性客体表面的潜手印。

| Abstract: | Objective To explore the application of small particle TiO_2 reagent on development of latent fingerprints.Methods(40) Fingerprints on six different kinds of substrates,which were preserved one day and seven days,and they were developed by SPR(small particle reagent).Results The fingerprints preserved for one day and seven days have not evident difference,but the developing result of sebaceous fingerprint was better than the eccrine fingerprints.Conclusion The small TiO_2 particle reagent is effective reagent for latent fingerprints on the non-porous surfaces. |
