近岸水域的

The floating causeway pier system studied in the thesis is set along sea. It is usedfor the load and unload of the low-freeboard ship such as lighter or small-typetransportation ship and as an emergency facility of transportation shoreward. Inaccording to the requirement of mission, the system should be adapt to many shipsand can be assembled and unassembled.

本课题所研究的浮式栈桥码头系统是一种设置于近岸水域，用于驳运船、小型运输船等低干舷船舶物资、装备、车辆实施海上卸载并向岸上输送的应急装备，根据任务要求，该系统应具有适应不同船型、可拼装拆卸的特点。

Therefore, it is impossible for M. mongolica to dominate in zooplankton community in oligotrophic coastal waters. Our results suggest that ecological effects of M. mongolica on structure and function of food web are neglectful in oligotrophic nearshore waters, however, dynamics of population of this species in eutrophic coastal waters and its ecological effects require a further careful investigation.

根据上述结果我们初步推断：蒙古裸腹溞在贫营养型的海洋沿岸带水域中形成较大的自然种群并对近海食物网结构和功能产生重大影响的可能性不大，但该溞在富营养化近岸水域中的种群动态及生态学效应有待进一步研究。

Contents of Zn, Cu, Cd and Pb in Shell of oyster and offshore water from Dalian gulf, Laohu beach, Fujia Zhuang beach, Lingshui bay, Lvshun and Jinzhou are studied by Anodic Stripping Voltammetry in order to establish a relationship between offshore seawater and heavy metal content in shells. Through monitoring the seawater and shells we researched whether the shells could replace the soft tissue of oyster shells as an indicator of marine environment changes in hope of finding a more convenient and accurate carrier for monitoring marine heavy metal.

本论文以大连湾、老虎滩、付家庄、凌水湾、旅顺及金州六个区域的近岸海水及牡蛎贝壳为研究对象，应用阳极溶出伏安法对其锌、镉、铅、铜的含量进行分析，旨在通过监测大连近海水域及贝壳重金属含量来研究二者的相关性，探索是否可以利用贝壳替代贝类软组织来指示海域环境的变化情况，从而找到一种更为简便、更为可靠的监测海洋重金属的载体。

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。
