摘　　要：综述了气力输送和气固流态化过程中绝缘粉体的静电测量技术,包括法拉第筒法和静电探头法,分析了这两种方法的优缺点,指出应在发展新型粉体静电测量手段的基础上,着力于探究静电产生的机理及主要影响因素,从而在根本上减少静电的产生和积累。The electrostatic measurement techniques for insulating powders in the process of pneumatic conveying and gas-solid fluidization were summarized. Two methods of Faraday cup and electrostatic probe were introduced and the merits and demerits of them were analyzed. Point out that it should attach importance to research into the mechanism of generating static electricity and main influencing factors, and consequently reduce static electricity generation and accumulation.
