摘　　要：随着痕迹检验在刑侦等领域的重要性日益凸显,汗潜手印作为常见且关键的痕迹证据备受关注。文章选取“502”胶、“414”胶、“454”胶、“460”胶、“496”胶等瞬间胶,以及304不锈钢、PP塑料、亚克力、玻璃、T2紫铜等非渗透性客体,在相同环境下进行多次实验、对比,系统分析各瞬间胶在不同条件下对汗潜手印显现的效果差异以及显现的清晰度、完整度以及稳定性,以找出适用于显现特定非渗透性客体上汗潜手印的瞬间胶。实验结果表明:“414”胶适合用于T2紫铜上的汗潜手印显现,“460”胶适合用于304不锈钢上的汗潜手印显现,“414”胶适合用于PP塑料上的汗潜手印显现,“496”胶适合用于亚克力上的汗潜手印显现,“454”胶适合用于玻璃上的汗潜手印显现。With the increasing importance of trace inspection in criminal investigation,latent fingerprints have attracted much attention as a common and key evidence.In view of this,the article selects instant adhesives such as 502,414,454,460,496,as well as non permeable materials such as 304 stainless steel,PP plastic,acrylic,glass and T2 copper,and conducts multiple experiments under the same environment.Through comparison,the differences in the effect of each instant adhesive on the manifestation of latent fingerprints,as well as the clarity,integrity,and stability of the manifestation were analyzed,in order to find the instant adhesive suitable for displaying latent fingerprints.The experimental findings show that 414 adhesive is suitable for latent fingerprint display on T2 copper,460 for 304 stainless steel,414 for PP plastic,496 for acrylic and 454 for glass,respectively.
