血迹形态分析实验室建立的探讨

血迹是命案现场特别是机械性损伤致死的现场中最常见也是最重要的痕迹物证,血迹的分布和形态对现场分析起着关键性作用,与现场勘验、法医物证检验及法医病理检验的情况相结合,便能为犯罪现场重建提供客观、科学的依据。在我国,虽然血迹形态分析的实际应用非常普遍,但理论性和系统性研究相对滞后。因此,建立血迹形态分析实验室的目的就是要创建血迹分析的实验平台,创新对不同承载客体上血迹的发现、显现和提取的方法,计算分析血迹形态模拟的实验数据,研究血迹的形态变化和形成机制,更好地综合利用血迹形态分析现场的理论,为教学、研究和办案积累经验,进一步提高血迹形态分析结果在法庭科学证据中的地位和作用。

Bloodstain is the most common and most important trace evidence in the murder scene, especially in the murder scene of mechanical injury. The morphology and distribution of blood play a key role in the analysis of the scene, which can provide objective and scientific basis for the reconstruction of crime scene, combined with the scene investigation, forensic medicine and forensic pathology examination. In our country, although the application of the bloodstain pattern analysis is very common, the theoretical and systematic research is relatively backward. There- fore, the purpose of establishing the laboratory is to create an experimental platform for bloodstain analysis, and to innovate the method of discovery, appearance and extraction of blood on different carrying objects, to calculate and analyze the experimental data of bloodstain pattern simulation, to research the formation mechanism and morphological changes of bloodstain, and to comprehensively apply the theories of analyzes the crime scene with bloodstain pattern, in order to accumulate experience for the teaching, research and practical work, and further improve the status and rote of the results of the bloodstain pattern analysis in scientific evidence on the court.
