然后按水源的情况将另一端套在自来水龙头上或放入供水池中（进水口必须完全侵入水中），进水口装有过滤器，以免吸入的杂质损坏高压水泵。

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。

The distance between settled releaser and inlet of raw water is 180 cm, and the range of distance between pensile releaser and inlet of raw water is 60-90 cm. The flow of pensile releaser is 2-3 times as much as settled releaser.

较为合理的布置为：固定式释放器S与原水进水口距离为180 cm，悬挂式释放器P与原水进水口的距离在60～90 cm之间。P与S的流量比控制在2～3之间。

The system calculation and analysis on stress field, displacement field and failure zone indicate the high rock slope of spandrel groove and water inlet are stable if they are excavated in the designed slope ratio.

通过对拱肩槽及进水口边坡的应力场、位移场和破坏区域模拟计算表明：拱肩槽、进水口边坡在拟订的开挖坡比条件下整体均处于稳定状态。
