| 摘 要： | 为了改善潜在手印显现的实验教学质量,从手印显现的原理及显现效果的影响因素出发,综合设计了手印显现的实验教学模式。选择金粉刷显、银粉刷显、磁性粉刷显、502胶熏显和502胶熏显→罗丹明6G染色5种方法分别对铝合金表面遗留时间1、7、15 d的手印进行显现,并采用分值量化的方法对显现效果进行评价,比较不同方法在不同遗留时间条件下的显现能力,得出了针对不同遗留时间的手印显现方法的适用性选择标准。

| Abstract: | order to improve the experimental teaching quality of the potential fingerprint display,the experimental teaching mode of the fingerprint display is comprehensively designed on the basis of the principle of the fingerprint display and the influencing factors of its effect.Five methods of gold powder displaying,silver powder displaying,magnetic displaying,502 glue fumigation displaying and 502 glue fumigation displaying→rhodamine 6G dyeing are selected to display the fingerprints on the aluminium alloy surface for 1,7 and 15 days respectively.The evaluation of rendering effect is carried out by means of quantification of scores,and the rendering ability of different methods under different conditions of the left time is compared.The selection criteria for the applicability of fingerprint rendering methods with the different left time are obtained. |
