The results suggested that the exponential variation of volumetric charge density with the bulk electrolyte concentration is more favorable to describe the membrane potential and to evaluate the induced fixed charge density.

结果表明，当体积电荷密度随浓度呈指数变化时，拟合的膜电位与实验结果更接近，得到的固定电荷密度更精确。

The results showed that: the influence of the aquaculture process on aquaculture water determined by type of aquaculture; the influence of aquaculture process on the water temperature, salinity and pH value were not wide.the descent of pH value was related to feed coefficients ; the dissolve oxygen of water in outfall was lower than the water in infall,but the concentration still maintained at the saturation level, is mainly affected by density of aquaculture ,rate of feed and artificial measures of increasing oxygen ;the major form of inorganic nitrogen was nitrate-N;the concentration of inorganic nitrogen and the organic matter tended to increase ,but the ammonium to decline ,this was relation with density of aquaculture ,rate of feed and variation of the different inorganic nitrogen form ; concentration of phosphate-P was low in outfall of pond , related with phosphate-P precipitating, as flowing water speed slowly in outfall;This phenomenon that the total number of bacteria and coli form group of water in outfall was lower than the water in infall , this caused by measures of sterilization and disinfection .

结果表明：养殖过程对水体影响与养殖类型有关。养殖过程对水体的水温、盐度和pH影响不大； pH下降与饲料系数高有关；溶解氧含量排水口比进水口低，但仍维持在饱和状态，与养殖密度、投饵率和人工增氧有关。硝酸氮是无机氮的主要存在形式，无机氮和有机物含量有升高趋势，氨氮有下降的趋势，与养殖密度，投饵率和各种无机氮之间的相互转换有关。活性磷酸盐含量在排水口含量下降，与排水口流水速度慢，磷酸盐沉淀有关。生物指标细菌总数和大肠杆菌总数在排水口比进水口低现象普遍存在，这与养殖场杀菌消毒等措施有关。
