Particle Charging in Electrostatic Precipitation电收尘器粒子荷电.pdf

articI e tna i n clectrostatic age particle charge is comparatively rging small although not negligible. It is clear, therefore, that electrostatic precipitation recipitation and other similar technical processes must include particle charging as an inherent part of the process. H. J.
