摘　　要：根据紊流传质原理建立了粉尘粒子传输方程,抛弃了 Cooperman和Leonard 理论的不合理边界条件的假设,确定新的粒子收集效率公式。同时对影响粒子沉降的紊流扩散系数做了精确分析,成功地解析了非 Deutsch 现象;并把粉尘比电阻与粒子收集效率有效地结合起来,克服了在静电收集理论中长期悬而未决的问题,建立了非稳态静电收集理论。Based on the principle of turbulent mass transfer, a mathema-tical model of particles transfer has been developed to get rid Of those crudeassumptions of boundary conditions suggested by Cooperman and Leonard,witha new collection formula expressed.An accurate analysis was also made to theturbulent diffusion coefficient which will affect particles settling,thus explai-ning successfully the non-Deutsch phenomena and combining effectively thedust resistivity with particles collection efficiency. In this way the problempending for long time in the theory of electrostatic precipitation is solvedavailable to set up an overall non-steady theory of electrostatic precipitation.
