| 摘 要： | 粉末法是现场上显现潜指纹最常用、最方便的方法,即用玻璃纤维刷或毛刷将各种粉末刷到指纹区域,其通过物理机械或静电作用与乳突纹线上的指纹残留物发生吸附,而没有指纹残留物的小犁沟以及指纹承载体则不会吸附上粉末.最终的结果就是粉末粘附到乳突纹线上,与未粘附粉末的小犁沟和承栽体形成反差,从而显出潜指纹.

| Abstract: | Powder-dusting is the most convenient method commonly used on crime scene to develop latent fingerprints.Namely the fingerprints are developed by dusting various powders through fiber glass or hair brush on suspected area.Then the powders adhere to the fingerprint residue on friction ridges by physical or static action,while the furrow and background wouldn't absorb the powders.The final result is that powders adhere to the friction ridges forming a contrast with the furrows and object,so latent fingerprint... |
