警犬技术在爆炸案件现场中的物证搜索技术研究

Research on material searching technology by using police dog technology in the scene of the explosion case

爆炸案件现场物证除常规物证外,还有爆炸案件所特有的物证。爆炸案件现场物证具有分布广泛、炸前炸后形态不一且难于发现的特点。但其分布依然存在客观规律。物证搜索犬搜索物证主要有无物寻物和有物寻物两种模式。为提高物证搜索犬在爆炸案件现场搜索物证的效率,保障带犬民警及警犬的安全,带犬民警应严格遵守搜索程序,依据爆炸案件现场物证分布规律有目的指令物证搜索犬作业。

In addition to the conventional material evidence, there are specific material evidences in the explosion case.The material evidence of the explosion case has the characteristics of wide distribution,different shape and difficult to be discovered. But there is still an objective law in its distribution. There are mainly two modes for the material evidence searching dogs to search for material evidence,looking for the evidence without material and with material. In order to improve the efficiency of material evidence searching dogs in the scene of explosion, and to guarantee the safety of the police with dogs and the dogs, the police with dogs should strictly abide by the searching procedure,according to the distribution of material evidence in the explosion case, intensively command the searching dogs to search.
