| 摘 要： | 目的研发一种具有荧光特性的黄湿粉,以提取遗留在不同客体上的不同种类的手印。方法在100mL温水中加入适量的表面活性剂,溶解后加入100g荧光黄颜料,选用不同种类客体及不同种类物质手印进行显现实验,比较显现效果;结果遗留在光滑非渗透性客体及半渗透性客体表面的汗潜、油潜手印,显出的手印纹线流畅、反差强、荧光强;结论荧光黄湿粉可适用于光滑非渗透性客体及半渗透性客体表面新鲜或较新鲜汗潜手印、油潜手印及血潜手印的显现。

| Abstract: | Fingerprints on non-porous and semi-porous surfaces were developed with fluorescent yellow wet-powder experi- mentally and the results showed that fingerprints on non-porous and semi-porous surfaces can be developed with good contrast and bright fluoresce. The fluorescent yellow wet-powder method is very effective for developing the latent perspiration, oil and blood fingerprints deposited on non-porous and semi-porous surfaces. |
