3.This paper reported the experiment on the intake,growth and survival of Babylonia aerolata(mean body weight=0.27g,mean shell length=11.2mm) fed with Loligo oshimai under different salinity in small water volume conditions. The results showed that optimat salinity for B.aerolata was higher than 21 and the survival salinity was higher than 15.In the salinity range from 21 to 33,the daily rate of feeding by B.aerolata was 10.2%~11.6%,the daily growth in body weight and in shell length were 11.3~12.0mg and 123.1~141.9μm respectively.
方斑东风螺的适宜盐度在21以上,适应盐度下限应为15.在21~33的盐度范围内,小水体的实验条件下,平均体重0.27g、平均壳长11.2mm的方斑东风螺,投喂小管枪乌贼,日平均摄食率10.2%~11.6%,体重日均生长11.3~12.0mg,壳长日均生长123.1~141.9μm.
4.Based on the test of drainage salinity effect in different clay interlayer and the analsis of thickness of drainage salinity layer, the design parameter of effective drainage salinity semidiameter, amount of sand-hole and semidiameter of hole were put forword.
通过对不同层位的粘土夹层土壤的洗盐效果试验研究,分析了脱盐层厚度、计划脱盐层脱盐效率,提出了有效洗盐半径的概念、砂孔数量及孔径等设计参数,并制定相应的洗盐制度。
5.The distribution of DOC was mainly controlled by dilution processes in areas where the salinity is greater than 1.6. In areas where the salinity is between 0-1.6, the concentration of DOC increased with increasing salinity.
在盐度大于1.6的河口区,溶解有机碳的分布主要受海水稀释作用控制;
6.Based on petrophysical experiments and water-rock reaction,surface physics and electrochemistry theories,mechanism of water saline type and salinity effect on parameters m and n of Archie equation and parameter B of Waxman-Smits model are studied. Parameters m,n and B are not only related with salinity,but also show different characteristics in different range of salinity.
在岩石物理实验的基础上,综合运用水岩相互作用、表面物理、电化学等方面的理论,研究水型及矿化度变化对阿尔奇模型中的m、n值以及Waxman-Smits模型中B参数的影响及作用机理.
7.(2)the T - S curve of the Kuroshio water is S-shaped,indicating that four water masses exist from the surface to the lower , i. e. , the high-temperature and subhigh-salinity surface water,the high-salinity subsurface water,the low-salinity mid-water and the low-temperature deep water, the properties of the four water masses change with season.
(2)黑潮水的T-S曲线呈S型,自上而下有四种类型水,即高温次高盐的表层水、次表层的高盐水、中层低盐水、深层低温水.
8.The salinity tolerance of Israel red tilapia has been studied at these salinity gradients: 0, 15, 25 and 32. The salinity tolerance of Israel red tilapia is stronger than Oreochromis niloticus and O.
在0、15、25及32四种盐度梯度下,测试了以色列红罗非鱼仔鱼、稚鱼及幼鱼的耐盐性。
9.The surface layer water temperature is 25.8℃,salinity l2~17.6, pH 8.5~8.6,transparency 1.5~1.6m in the red tide area,respectiuely. lt may be the primary reason of this red tide that the mass fresh water coming from land led to the decrease the salinity and increase the nutrients,etc.
赤潮海区的表层水温25.8℃、,盐度12~17.6.pH8.5~8.6,透明度1.5~1.6m,大量富含营养物质的陆源淡水入海,可能是这一海区海洋褐胞藻赤潮的主要起因。
10.The annual variation of ITF is that it transfers less water volume during El Nino period, with the temperature reducing and salinity rising. But during La Nina period, exactly the opposite of the former, ITF transfers more water volume whi ]e experiencing temperature rising and salinity reducing.
ITF的年际变化是:印度尼西亚贯穿流在E1 Nino期间体积输运较小,海面温度降低,盐度增加,与之相对的La Nina期间体积输运增大,海面温度升高,盐度降低。
