For measurement of sediment spatial concentration of nearshore seawater,a turbid water sys-tem with several kinds of particles is investigated from the viewpoint of the characteristics of particles.Firstly.the classical physical and chemical conductivity formula is extended to macro-particle(such assand)conductivity formula.Secondly,the Fricke formula suitable for only one kind of particles is ex-tended to the conductivity formula suitable for several kinds of particles.Finally.the multi-particle conduc-tivity formula is applied to the measurement of sediment spatial concentration. 相似文献
