摘　　要：目的研究探索“502”胶溶液显现手印的方法。方法以石油醚为分散剂,添加对苯二酚作为显现增强剂,配制“502”胶显现液。结果能够显现非渗透客体上油质加、减层手印、加减层混合手印及普通汗潜手印,其显现效果与“502”胶熏显法非常相似。结论该方法具有方便、快捷、灵敏等特点,是“502”胶显现手印技术的重要补充。A new superglue solution method to develop latent fingerprints on non-porous objects was estabished, The solution was made by add petroleum ether as dispersant and hydroquinone as intensifier. The developing effect is very similar to that of vacuum fuming method. The experimental results show that this method can be used to develop various kinds of fingerprints on non-porous objects, which is complement to the conventional superglue method.
