| 摘 要： | 目的 分析短波紫外反射照相显现铝制板框上汗液指印效果差异形成的原因.方法 利用短波紫外反射照相并用不同的打光方式对铝制板框汗液指印进行显现.结果 打光的角度不同,汗液指印的显现效果截然不同,并且在小角度入射的情况下,铝制板框上的汗液指印显现效果和玻璃载玻片上的汗液指印显现效果也明显不同,铝对短波紫外高反射率的特性引起了汗液指印显现效果的不同.结论 针对铝制板类的检材,在利用短波紫外进行汗液指印显现时需要明确不同情况下相应的显现效果.

| Abstract: | Sweat fingerprints on the aluminum surface were developed by UV reflection photography and it was found that the development results were varied with the different incidence angle of UV light. The explanation about this phenomenon and suggestions when use this method to develop fingerprints on aluminum surface were given by author. |
