摘　　要：目的　建立了一种物理显影液显现潮湿或者浸泡渗透客体表面血潜手印的新方法。方法　把检材浸泡在配制好的物理显影液中 ,还原的银粒子吸附在血潜手印部位显现出手印纹线。结果　显现出手印纹线为黑灰色 ,纹线连贯 ,反差明显。结论　物理显影液能够有效地显现出潮湿或者浸泡后手渗透客体表面血潜手印。Objective To set up a method for developing latent blood fingerprints on porous surfaces with sliver physical developer. Method Porous surfaces with blood latent fingerprints was soaked with sliver physical developer solution, sliver particles attached to latent fingerprints. Result Color of ridges developed by the method is gray-black, continuous, and the contrast is high. Conclusion Sliver physical developer is effective for the development of latent blood fingerprints on porous surfaces.
