摘要
为了克服硝酸银显现法的缺点,笔者对原有的硝酸银显现法进行了改进,用新配方硝酸银显现液显现各种纸张(打印纸、普通纸、报纸、牛皮纸等)上的汗潜手印,采用涂抹法,不需曝光即可显出效果较好的手印,手印纹线清晰、流畅,效果稳定,易于保存,使硝酸银显现法得到了进一步的发展和完善。
The silver nitrate solution for developing latent fingerprint on paper was modefied with metol mixture. With the new solution, the developed fingerprint is easy to be preserved. The ridges of the fingerprint are distinct, smooth and complete.
