摘要
通过对火灾中铜导线熔痕的组织结构进行X射线衍射仪分析,找出了铜导线一次短路熔痕、二次短路熔痕、火烧熔痕在物相组成、晶面取向和晶格畸变等参数的特征规律,建立了铜导线熔痕组织特征的技术鉴定方法,为火灾物证鉴定提供定量技术依据。
Utilizing the X-ray diffraction, analyzed the organization structure of copper wire melting marks in fires, discovered the characteristics and laws of copper wire direct short circuited melted mark, secondary short circuited melted mark, and fire melted marks in terms of phase composition, crystal orientation, and lattice distortion, and established the technical evaluation methods of organizational characteristics of copper wire melting marks. It serves as quantitative technical basis for identification of fire material evidence.
