电镜能谱认定方法在起火点认定中的应用

Application of electron microscope energy spectrum identificationmethod in identification of fire point

电镜能谱认定法在起火点分析过程中是一种准确性相对较高的技术方法,实际应用时,主要以起火点受热性能为基础,通过对火灾现场受热时间最长区域燃烧灰烬碳含量进行分析的方式,完成火点的判定工作。在简述认定起火点的重要意义、常用方法的基础上,分析了电镜能谱认定法认定起火点的设备及步骤,并针对电镜能谱认定法展开模拟试验,同时总结了电镜能谱认定法认定起火点的注意事项。希望为火灾原因调查工作及后续火灾预防工作提供帮助。

Electron microscope energy spectrum identification method is a relatively accurate technical method in the process of fire point analysis.In practical application,mainly based on the heating performance of the ignition point,the determination of the ignition point is completed by analyzing the carbon content of the burning ash in the area with the longest heating time at the fire site.On the basis of briefly describing the significance and common methods of identifying the ignition point,the equipment and steps for identifying the ignition point by the electron microscope energy spectrum identification method are analyzed,and a simulation test is carried out for the electron microscope energy spectrum identification method.At the same time,the precautions for identifying the ignition point by the electron microscope energy spectrum identification method are summarized.It’s hoped to provide help for the investigation of the cause of the fire and subsequent fire prevention work.
