盐度

You should therefore use a hydrometer to keep track of gravity, and add salt to bring up the salinity when needed.

因此，你必须使用hydrometer ，以保持轨道的重力，并添加盐来带出盐度在需要时。

When using a salimeter hydrometer, the measurement should be between 4 and 6 % at 25°C (77°F).

使用盐度计时，25°C (77°F)时的测量值应介于4 到6%之间。

Sea water hydrometer Floating on the sea water, the hydrometer is transparent, and is easy to use and reads easily with accurate numbers.

海水比重计浮于水面的海水比重计，海水比重、盐度、显示精确，使用简单，读数容易，透明度高。

The environmental factors such as temperature, salinity, pH and DO were investigated in 2001. Results indicated that the high temperature above 24 癈 was the important incitant.

综合对养殖海区各温度、盐度、溶解氧和pH值等主要环境因子季节性变化的分析结果，分析认为，24℃以上的高温是栉孔扇贝发病的重要诱因。

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。

Based on the results of water quality (physical and chemical factors: water temperature, salinity, pH, DO, DIN, PO4-P, COD, and biomarker-indicated: total bacteria and Coliforms) determining from the 4 pools and infall, outfall of the Xishan Island aquaculture pond, the variation characteristics of water quality in infall, outfall of pond and its reasons were analysised and discussed.

结果表明：养殖场和进、排口水体温度、盐度变化不明显，pH下降与养殖周期有关；营养盐含量增加，在不同养殖种类、养殖周期和养殖饲料系数变化不同；受消毒杀菌等措施影响下细菌总数与大肠杆菌总数明显减小，而养殖周期长的池塘，细菌总数仍增加，大肠杆菌总数减少幅度变小。

Increases gill Na,K-ATPase actiity of killifish, tilapia Oreochromis mossambicus and Oreochromis

用GH或IGH- I处理killfish， tilapia， striped bass后，增加了其对盐度的耐受力或增加了Na+\K+-ATP酶的活性。

The salinity of the earth's oceans is about thirty-five parts per thousand, meaning that there are about thirty-five grammes of dissolved solids and gases in one kilogramme of water.

地球海洋里的盐度大约为35%，意思是说，在每公斤的水中约含有35克溶解的固体和气体。

The salinity of the earth's oceans is acres thirty-five parts per thousor, meaning which here are acres thirty-five grammes of dissolved solids or gases in first kilogramme of waterdrop.

地球海洋里的盐度大约为35%，意义是说，在每公斤的水中约含有35克溶解的固体和气体。

The interannual variation of the temperature and salinity was mostly obvious at south of the Kuroshio bend.

吕宋海峡以西的温度水平梯度在秋季最弱，而盐度水平梯度则在夏季最弱。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
