| 摘 要： | 由分析静电放电火花羔火过程的物理特征和静电放电火花的点燃特性。根据静电放电火花的能量大小、放电火花空间分布范围和放电火花持续时间，研究静电放电火花实际点燃可燃物的可能性大小，给出6种典型静电放电火花的实际点燃能力。根据灰色系统理论，分析静电放电火花点火源序列和可燃物危险性序列之间存在的关联性，对静电放电火花的实际点燃危险性进行定量评价，将工业生产条件下的静电放电火花点燃危险性分为4级。

| Abstract: | The physical characteristics of the ignition processing caused by electrostatic discharge(ESD) sparks and the igniting characteristics of the ESD sparks are investigated. The spark energy of ESD, the space distributions and the duration of ESD sparks are the key characteristic data which determine the possibility of ignition caused by ESD sparks. The ignition ability data for six kinds of typical ESD sparks are provided. According to the gray system theory, it is possible to identify the hazard of ESD spark ignition by means of the correlative relationship between the sequence of ignition source(ESD sparks) and the sequence of hazard for the combustible substance. Under the conditions of industry production, it is reasonable that the hazard of ESD spark ignition is classified into four grades by adopting the above results. |
