关于枪击残留物检验认定枪支方法的研究

On the Method of Determining Guns with Gunshot Residuum Examination

枪击残留物主要包括燃烧或部分燃烧的发射药、底火残留物和微量金属物质,通常会遗留于射击者、被射客体以及枪支等部位。随着科学技术及分析水平的提高,尤其是扫描电镜/能谱法、中子活化分析技术、毛细管电泳技术等技术日益普及,射击残留物的检验水平有了很大发展,对射击残留物的理论研究以及检验技术研究,成为法庭科学及刑事技术工作中的重要内容。

The residuum of the shooting are mainly from combustion or in part, not the burning propellant, primer residues and trace metals, and are usually left behind in the shooting, and was shot as well as firearms and other parts of the object. As science and technology and the increasing of the level of analysis, especially the growing popularity of technology, such as scanning electron microscopy / spectroscopy, neutron activation analysis techniques, capillary electrophoresis technology, the testing level of residues has made significant progress. The theoretical research and testing of gunshot residuum become an important content of court science and criminal technology work.
