燃爆事故研究的根本目的,就是通过现场调查、残骸分析、模拟测试、故障再现、综合分析等程序,准确地确定事故性质,寻找事故的直接原因,提出有效的预防措施。在许多事故现场,往往同时存在静电放电、电气短路两种可能火源。如何准确地判断事故性质──是静电放电引燃还是电气短路 The fundamental purpose of the study of blasting explosion accident is to accurately determine the nature of the accident, find the direct cause of the accident and put forward effective preventive measures through field investigation, wreck analysis, simulation test, fault reproduction, comprehensive analysis and other procedures. In many accident scene, often exist at the same time electrostatic discharge, electrical short circuit two possible sources of ignition. How to accurately judge the nature of the accident ─ ─ electrostatic discharge or electrical short circuit
