摘要： 目的 利用环境扫描电镜-X射线能谱仪（environmental scanning electron microscope and energy dispersive X-ray microanalyser，ESEM-EDX）研究电流斑微观形态特征及元素构成，以期为电流斑及电击死的鉴定提供更准确、客观的依据。 方法 用ESEM-EDX检测5例电流斑的扫描电镜形态、金属颗粒的形态及其元素组成。 结果 电流斑及周围皮肤可见电穿孔、金属熔珠，熔珠主要由铁、铜、铝等常见金属元素和金、钛、钡等人体少见的金属元素构成。 结论 ESEM-EDX检测可为电击死的鉴定提供客观的依据。

Abstract: Objective To provide objective proof on diagnosis of electrical current mark in electrocution, the environmental scanning electron microscopy and energy dispersive X-ray microanalyser（ESEM-EDX） were adopted to study the microscopic morphological characteristics and elemental composition of electrical current mark. Methods Morphological characteristics of electrical current marks, the elemental composition and morphology of metal particles were studied with ESEM-EDX. Results The electroporation and metal melted beads could be found in the electrical current marks and skin around them. The metal melted beads mainly composed of common metal such as iron, copper, aluminum and some uncommon metal including gold, titanium and barium. Conclusion ESEM-EDX can be applied in forensic diagnosis of electrocution.
