近年来，显生宙以来海水锶同位素的变化曲线不断得以补充和修正，已建立起具有全球一致性、可对比的海水锶同位素变化曲线背景值，为锶同位素的应用奠定了基础。

Seawater some measurable environmental characteristics of the apparent differences in the vertical direction of the water layer thermocline indicate their presence on the nature of the underlying sea water.

海水中某些可量度的环境特征在铅直方向发生明显差异的水层跃层的存在表明其上、下层海水性质。

When surface waters are cold, deeper depths are allowed to upwell, bringing these essential nutrients toward the surface where the phytoplankton may use them.

当海水表面温度下降时，较深一些的海水就会上浮，同时把这些必须营养成分带到水面处，供生活在那里的浮游植物生长的需要。

The upwell ing brings the thermocline—the boundary layer between deep, cold water and the warm water of the surface—up as high as 30 feet from the top.

上升流使得局部温越层(深处的冰冷海水和表面的温暖海水交界处的水层)可鼓出10米之高。

Potable water is obtained from sea water (or other non-potable water) in reservoir 20 by passing a stream of atmospheric air over briaded-cotton wick plates 22, which are saturated with the sea water, so that the air takes up water-vapour, drawing the moistened air by if an 25 in section 17 where the air is cooled by coils 32, 33 and water-vapour condenses.

的食水是从海水在水库20通过流大气超过briaded棉芯板22 ，这是饱和的海水，所以认为空气占用了水汽，绘制湿空气中，如果一25日在第17条的地方，空气冷却线圈32 ， 33和水汽凝结。

Based on the high-resolution analysis of planktonic foraminiferal isotope and organic carbon of 91 sediment samples from two box cores located respectively in the southern and northern slopes of the South China Sea, the changes of sea surface temperature and paleoproductiviy of the past 2400 years were reconstructed. The sea surface temperature and the depth of thermocline varied in different stages during the late Holocene, with some short-term climate events such as the Little Ice Age.

对南海南、北陆坡两个箱式柱状样中91个沉积物样品进行了高分辨率的稳定同位素和有机碳分析，获得最近2400年以来上部海水温度和表层古生产力的记录，发现晚全新世南海的表层海水温度和温跃层呈现阶段性变化，且有小冰期等短期气候事件。

The effects of small range of changes of Ca(superscript 2+) and Mg(superscript 2+) concentrations (0-100 mg/L) on the survival rate and growth were studied in the larvae from the mysis Ⅲ(M3) to the postlarval 10 (P10) stages of Litopenacus vannamei. Larvae were raised in artificial water prepared from condensed sea water and tap water.

采用浓缩海水与自来水调配的基础海水，以凡纳滨对虾Ⅲ期糠虾幼体(M3)作为试验对象，在小范围(0~100 mg/L)内调节育苗用水中Ca(上标 2+)、Mg(上标 2+)浓度，以L9(3^4)正交表设计，研究育苗用水中不同Ca(上标 2+)、Mg(上标 2+)浓度对凡纳滨对虾M3育成仔虾(P10)的成活率和生长的影响。

During the sediment of late Cretaceous Taizhou Formation and Paleocene Epoch Funing Formation, Subei Basin have formed dark shale containing lots of ostracoda that include predominated whole basin E12 Formation and E14 Formation and local K2t2 Formation, which have become main source rocks of the basin.

海侵的原因，可能是从晚白垩世晚期起，中国东部的地应力条件以引张力占优势，并在华北－渤海湾、苏北－南黄海和东海陆架区，发育了一系列为早第三纪巨厚沉积物所充填的半地堑箕状盆地，海水由东海向黄海海侵，造成陆架上箕状盆地在短时期内与海水相通。

Euphotic layer of the sea refers to the layer where phytoplankton can photosynthesize;therefore,the retrieval of the euphotic depth is in favor of estimating ocean primary production.

海水真光层是指海洋浮游植物进行光合作用的水层，海水真光层深度的反演有利于对海洋初级生产力的估算。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
