查询词典 tidal power

Sediment from river is not the main source of the Rushan Bay now any more ,which leads to the change of balance of sedimentation power. Sediment will transport because of the drive of hydrodynamic elements in macroscopic view .Direction of suspended load is basicly the same as tidal current .Flood tide makes suspended load transport to tip of the inner Bay and to the Mouth in exterior Bay .The direction of longside sediment transport in two sides of the Mouth mainly focus in the Mouth .Because the coastline along the exterior Bay is very meandering and it belongs to the type of bedrock ,besides some sediment going into the inner Bay ,so actual net sediment discharge rate is less than calculation .It develops an ebb delta out of the Mouth and forms tidal sand ridge ,tidal washing canal ,barrier bar and marine physiognomy ;The result of model simulation disclosures that differences of sediment erosion and siltation between single tidal action and wave-current action are very big .From the analysis of sediment composition、sediment sources and stability of beach and ridge ,this article gets the conclusion that the channel has the possibility to silt ,though the course maybe very slow.

通过分析研究文章得出如下结论：沉积物平面分布与水动力的时空变化存在很好的相关性；口门外发育落潮流三角洲，形成潮流沙脊、潮流冲刷槽、浅滩、拦门沙等水下动力地貌；乳山湾河流来沙已不是湾内泥沙主要来源导致沉积水动力平衡发生改变，宏观上表现在泥沙受水动力驱动发生不断运移；悬沙运移方向与涨潮流方向基本一致，湾内涨潮流带来的悬移质泥沙向湾顶运移，湾外悬移质泥沙主要向口门方向运移；湾口两侧岸段沿岸输沙方向均指向口门方向，由于乳山湾外海岸线曲折，两侧岸段以基岩为主，加之部分泥沙进入湾内，实际净输沙量小于计算值；数值模拟发现潮流单独作用与波流共同作用下泥沙蚀淤模拟差别较大；从沉积物组成、泥沙来源及滩槽稳定性三个方面分析，文章认为研究区存在航道淤积的可能性，但过程相对较慢。

The deal will eventually create Europe's biggest operator of offshore-wind energy ; both companies are big in renewable and clean energy, including solar and tidal power.

交易将最终建成欧洲最大型的陆风能源设备；两公司都是清洁及可循环能源行业的巨头，该能源包括太阳能和潮汐能。

Though often co-mingled, wave power is distinct from the diurnal flux of tidal power and the steady gyre of ocean currents.

虽然常常易混淆，但海浪能与潮汐力的每日涨落变化和海洋流稳定的环流是不同的。

Moreover, they are completely reliable, since tidal power comes from the constant pull of the Moon which tugs the tide up or down every 12 hours.

此外，它们是完全可靠的，因为潮汐能来自月球恒定的引力，月球每 12 小时吸引潮水涨或落一次。

Like wind turbines, but powered by the flow of water instead of the flow of air, tidal power turbines transform tides or deep ocean currents into electricity.

就象风能涡轮机靠气流来驱动一样，潮汐能涡轮机是靠水流来驱动的，将潮流或深海洋流转化为电能。

More efficient ways to utilise wind energy and tidal power are being studied .

人们正在研究更有效地利用风能和潮汐能量的方法。

Nevertheless, because tidal energy have huge power, reserves many advantages. it is still very great importance to research and test tidal power generation.

然而，由于潮汐能蕴藏量的巨大和潮汐发电的许多优点，人们还是非常重视对潮汐发电的研究和试验。

Ocean power comes primarily in two forms: wave power and tidal power.

海洋权力的来源主要有两种形式：波浪能和潮汐发电。

Tidal power is a kind of flesh energy with high value and potential in use.

海洋潮流能是一种利用价值高、潜力巨大的新能源。

With Yangtze delta tidal flat as an example, through the analysis on the magnetic characteristics of tidal flat sediment and the study on the space distribution of heavy metal elements, this thesis discussed the impact to Shanghai sea bank brought by heavy intensity development, and the interrelation between sediment power effect and heavy metal pollution space distribution. Utilizing the advantage of artificial intelligence neural network, in conjunction with environmental chemical analysis, from the angle of view of sediment magnetic characteristics, it analyzed the connection mechanism between magnetic mines and heavy metal element within tidal sediments, and built a quantitative magnetical diagnosis model, in attempt to calculating the tidal heavy metal pollution status from the magnetic measurement data of sediments and assess it's impact to the environment.
