静电现象是生活和生产中常见的带电现象，特别是在石油化工业中，有许多伴随有爆炸的起火事故差不多都是静电放电造成的，因此静电的防护得到了普遍的重视。1静电的产生流体介质的带电主要归结为双电层的存在、固相本身的电离或是吸附液相中的一种离子等原因而带电。依据电量平
Electrostatic phenomena are a common phenomenon of electrification in life and production. Especially in the petrochemical industry, there are many spark accidents caused by explosions. Electrostatic discharge protection has gained universal attention. 1 Electrostatic generation The charging of the fluid medium is mainly due to the existence of the electrical double layer, the ionization of the solid phase itself or the adsorption of one ion in the liquid phase. According to the power level
