| 摘 要： | 目的为有效的提高纸张上汗潜手印的显现率。方法根据汗潜手印的显现原理，针对不同的纸张，分别运用硝酸银、茚三酮与DFO（1，8-二氮芴-9-酮）3种显现方法进行了实验，并对实验结果进行了分析比较。重点分析了这3种方法在显现不同纸张、不同遗留时间、不同汗液量的汗潜手印时的效果及其适用范围。结果为改善渗透性客体上的汗潜手印显现效果，提供科学的依据。

| Abstract: | Objective Fingerprints on different kinds of paper were developed by silver nitrate, ninhydrin and DFO, ande the results were compared and analyzed. The results showed that DFO is better for developing fresh fingerprints deposited on craft paper. Silver nitrate and ninhydrin were better for developing aged fingerprints. |
