1项目基本情况水中腐败尸体的死因鉴定是世界公认的法医学难题,在公安部重点研究计划项目资助下,课题组开展法医硅藻检验关键技术和设备研发,并取得重大突破:建立了微波消解新方法,该方法高效、环保,硅藻回收率高;建立了真空抽滤富集硅藻方法,发明了自动化多联真空抽滤设备,避免了硅藻损失;建立了扫描电镜观察新方法,种属鉴定准确,避免了硅藻漏检、误检;研发了膜透明-光镜联用法,解决了硅藻检验技术在基层难以推广的难题;研究
A project basic situation Identification of the cause of death of corpse in water corruption is a world recognized forensic puzzles, the Ministry of Public Security key research project funded projects, the forensic diatom inspection team to carry out key technologies and equipment research and development, and made major breakthroughs: the establishment of a new microwave digestion The method has high efficiency, environmental protection and high diatom recovery rate. A method for vacuum enrichment of diatoms by vacuum filtration was established, an automatic multi-vacuum filtration equipment was invented to avoid the loss of diatoms, and a new scanning electron microscope observation method was established. Is an accurate identification, to avoid the diatom leakage inspection, false detection; developed a membrane-transparent - light microscopy combined method to solve the diatom inspection technology difficult to promote the grass-roots problems; research
