“502”胶显现法指纹检测技术探究

The Study of Fingerprint Detection Technique by Using of “502” Glue

该研究利用“502”胶进行检测指纹。分别采用熏显法和滤纸贴附法进行指纹检测。通过使用“502”胶在黑色塑料袋、蓝色塑料袋、黄色塑料袋、黑色相纸、易拉罐、瓷碗、富光太空杯、玻璃片等不同承痕体上,将粘有花生油、机油、牛奶、可口可乐、大宝、SOD蜜等非汗液手印进行显现。获得了满意的结果。实验证明“502”是一种有效的检测指纹的方法。

The research was studied on the fingerprints detection by useing of “502” glue.Fuming and filter paper technique were respectively used to detect fingerprint.The fingerprint were appeared through the use of “502” glue on the black plastic bag,blue, yellow paper ,black paper,plastic bags,cans,plastic bags bowls,rich light space cup,glass and other marks on the body,with peanut oil,oil,milk,coke,dabao,SOD honey.A satisfied experiment result was obtained.It was proved that “502” glue acted as a effective method to fingerprints detection.
