前滩

It will result in changes of flow state and endangering the water works, because the longitudinal addend by scouring and lateral slope failure.

小浪底水库建成运用后，通过水库的调水调沙，改变了黄河下游的来水来沙条件，尤其是运用的前14年处于拦沙期，下泄清水，对河南河道的影响最为剧烈，对游荡性河段的河势变化将产生很大影响，河道纵向冲刷下切，横向滩岸坍塌，工程出险将大量增加。

Four lavish homes topped the list of the properties the government told a judge they would like to seize: the upper east side Manhattan apartment where Mr Madoff was kept under house arrest until his guilty plea on Thursday, as well as holiday homes in Montauk, New York; Palm Beach, Florida; and Cap d'Antibes, France.

美国政府向法官出示了一张清单，上面列出了他们想要没收的财产，高居榜首的是四所豪宅：位于曼哈顿上东城区的公寓，马多夫上周四认罪前就一直被软禁在那里；以及位于纽约州蒙托克、佛罗里达州棕榈滩和法国安提布岬(Cap d'Antibes)的度假屋。

They produce a barrier beach with an eroded zone in front and a lagoon or salt marsh behind.

它们形成了一个前有侵蚀带后有泻湖和盐沼的堤洲堰滩。

C The profile is of berm, which the section below the berm is concave. Using the polynomial curve to fit the shapes of the mean profile, the exponential equation of the equilibrium beach profile in South China was established, which has a general form: y=〓+ C. 2 It's obvious for the beach processes to vary with seasons. The main variation processes of beach profiles are composed of four kinds of mode which are the equilibrium profile mode, the berm mode, the foreshore mode and the bar mode. 3 Beach systems of the arc-shaped coast in South China exhibit an wide range of morphologic and dynamic variability with respect to both time and local environment.

此外，采用多项式曲线对平均剖面进行拟合，建立了华南海滩均衡剖面的指数公式y=〓C+。2）海滩具有较明显的季节性变化，海滩剖面的变化模式一般可分为均衡剖面模式、滩肩模式、前滨模式及其沙坝模式等4种。3）海滩不同岸段的动力地貌状态在同一空间上的分布具有一定的连续性，在时间上具有一定的更替顺序。

Hybrids of carbonate and terrigenous sediments Carbonate with terrigenous sediments are of characteristic from Emsian to Eifelian in stable shallow-sea faciesregion in Longmenshan area, and they can be classified evidently into hybrid Ⅰ and hybrid Ⅱ(Jingbaoshi-type). Type Ⅰ produced in mud shelf setting occupied hundreds of tempestite beds in which bottom cast、 hummocky cross bedding sandstones、 coquina were inter-beddded with shales that beared a great deal of verm traces、 bioturbations、 benthic communities dominative of brachiopods. Type Ⅱ in sand-mud-marl shelf was characterized by high-energy foreshore sandbeach facies and shelly bank facies.

碳酸盐与陆源碎屑混合沉积方面对微相、相特征、旋回样式、沉积机理研究表明，龙门山地区泥盆纪稳定浅海相区Emsian期和Eifelian期混合沉积十分发育，颇具特色，明显可以划分为两种类型：混积Ⅰ型，泥质陆棚背景下发育风暴沉积组构，幕式风暴期产生具丘状层理、底流冲刷构造的钙质砂岩、介壳岩，平息期则形成具大量虫管和生物扰动的深灰色、黄绿色页岩及海百合茎灰岩，腕足动物等大量繁盛；混积Ⅱ型，砂泥灰质陆棚背景下以发育高能前滨沙滩及生物介屑滩为特色，近滨至陆棚的砂泥灰互为混合，三者比例接近，肉眼难以区别确切岩石类型。

As we crawled out of the door and along the foreshore, more and more kept coming in.

当我们爬着出了屋子继续沿着前滩匍匐，有越来越多的鹅飞来。

The uneven stratum on the foreshore near the Lai Chi Chong pier is volcanic ash sedimentary rock. Displaying very distinctive foldings, faults and bedding structure, it is an ideal location for geological study.

荔枝庄码头附近一前滩凹凸不平的岩层，是经过地壳运动挤压而成的山火灰沉积岩，岩石的褶曲、断层及层理构造清晰展现，因此是极佳的地质考察地点。

When they had come inside the harbour they furled the sails and laid them in the ship's hold; they slackened the forestays, lowered the mast into its place, and rowed the ship to the place where they would have her lie; there they cast out their mooring-stones and made fast the hawsers.

当船只进入了畜水幽深的码头，他们收拢船帆，堆放在乌黑的海船里，松动前支索，使桅杆迅速躺倒在支架上，然后荡起木桨，划向落锚的滩岸。他们抛出锚石，系牢船尾的绳缆，足抵滩沿，迈步向前，抬着献给远射手阿波罗的丰盛的祭件。

The database of average coastal images obtained is used to analyze inter-tidal bathymetry and foreshore topography in short-term and long-term variations, such as the topographic change of Hsi-tzu-wan beach after the construction of two headlands with beach nourishment.

累积的海岸平均影像资料库则用於分析短期及长期间前滩及潮间带的海岸地形变化，如观测西子湾在实施人工岬湾及养滩工法后附近海岸地形之变迁。

North Beach is a San Francisco, California neighborhood bounded by the former Barbary Coast, now Jackson Square, and the Financial District south of Broadway (except North Beach institutions extend down Columbus to Washington and Montgomery, where the Black Cat originally was), Chinatown to the southwest of Columbus below Green, and then Russian Hill to the west, Telegraph Hill to the east and Fisherman's Wharf at Bay Street to the north.

北滩是加利福尼亚州旧金山地区范围内的前北非海岸，现在杰克逊广场，以及金融区南部的百老汇（除北滩机构延长了哥伦布华盛顿和蒙哥马利，在那里黑猫原），唐人街西南哥伦布低于绿色，然后俄罗斯山以西，电报山以东和渔人码头湾街以北。

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。
