摘要
在碘熏法显现潜在手印的基础上,针对大多数纸制品自身含有直链淀粉的特点,基于碘与淀粉的显色作用,创新地提出了利用加湿法固定显出手印的实验思路,并开展了相关的实验探究。用饱和碘水确定生活中常见纸制品的含淀粉情况,利用碘熏法显现这些纸制品表面的潜在手印,最后通过喷雾加湿和超声波雾化加湿使显出手印固定下来。
Based on color effect between iodine and starch,a fixing method for fingerprints on starchy paper products developed by iodine fuming through humidification has been proposed.A series of experimental inquiry has been carried out,including identification of starch in common paper products,latent fingerprint development using iodine fuming,and fixing of developed fingerprints by mist spray and ultrasonic atomization.
