导线熔痕特征的拍照技术

Photo Technique for the Characteristics of Wire's Welding Trace

通过实验的方法,利用近距照相的原理,对金属铜导线熔痕在不同光照方向和强度下进行拍摄,总结出熔痕外观特征的拍照方法,为火灾调查人员认定火灾提供了有效的记录手段。

By using the testing method and short-range photo principle, this paper takes pictures for wire's welding trace under different lighting directions and strengths, and sums up the photo methods for the visual characteristics of the welding trace, which provides effective recording means for the fire hazard investigators to recognize the fire hazard.
