查询词典 tidal current

This dissertation, based on (1) field investigations and observation along Jiangsu coastal environment (including: sea bottom and tidal flat sediment sampling, water depth, salinity, current velocity and direction, core drilling and so on);(2) integrative laboratory analyses of micropalaeontology, sedimentology and computer-processed mathematical statistics on over 300 samples and about 100 thousand foraminifera tests, try to find and formulize the relations between foraminiferal thanatocoenose and environment.

本文的写作基础是：通过野外进行的海岸环境调查和测量（主要调查项目有：水深、盐度，流速、流向、含沙量、底质采样、浅地层地震剖面仪探测、潮滩钻孔取样、潮滩探槽的挖掘与沉积物取样、观测等等）取得了环境参数和大量样品；在实验室运用微体古生物学、沉积学、数理统计与计算机分析相结合的方法，对所采集的现代表层沉积物和钻孔岩芯样品共计三百多个进行了分析研究，鉴定统计有孔虫标本十万余枚，研究有孔虫埋葬群特征与环境参数之间的定性-定量关系。

Our current-driven turbines operate in river (in-stream, free-flow, open-river or hydrokinetic run-of-river), ocean and tidal settings.

我们目前的驱动涡轮机的运作河（在流，自由流通的，开放的河流或hydrokinetic运行的河），海洋和潮汐设置。

However, such tidal overheight is often ignored in the current regional numerical simulation due to intensive computational requirement. Only the mean sea level is used as the fixed seaward boundary, which may wrongly predict the groundwater table position. Therefore, we aim to determine an equivalent seaward boundary through numerical modeling. The equivalent seaward boundary takes into account the tide-induced overheight effects.

然而，由于潮汐动边界处理的复杂性而导致巨大的计算量，在现有的区域地下水数学模型中，潮汐引起的海平面波动通常被忽略，仅仅以平均海平面高度作为模型的海岸边界条件，其预测出的地下水水位位置与实际情况可能会有一定的误差。

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。
