家用电热器具火灾残留物的SEM分析

SEM Analysis of Fire Residue for Home Electrical Appliance

摘要: 模拟家用电热器具火灾残留物，用SEM（扫描电子显微镜）对火灾残留物中的电热丝显微形貌进行观察.结果表明：在不同试验条件下，电热丝的显微形貌有明显的不同，可以直观、快速地鉴别家用电热器具在火灾发生之前所处的状态，为家用电热器具火灾原因的认定提供了一种新的技术方法.

Abstract: Simulating the fire residues of the home electrical appliance, the microscopic appearances of heated wire were observed by SEM. The result indicates that the microscopic appearances in different conditions are not same. Therefore, the state of the home electrical appliance before fire can be distinguished directly and quickly. This method provides a new technique for the recognition of fire reason.
