潮的涨落

In the present paper,we use a 3-D Eco-Dynamic model to study the turbulence effect induced by the tidal process on the vertical distribution of two main kinds of the phytoplankton,namely as diatom and dinoflagellate.

该文利用三维动力生态耦合模型研究了水体紊动对甲藻和硅藻垂向分布的影响过程，分析了涨落潮对甲藻、硅藻不同影响特性的机理。

The basal geomorphology structure of the Tidal-Basin System of the Tiaozini Sandbanks is watershed and tidal creek system. We analyses its formation, evolvement, geomorphology characters and development and discusses the main influence factors which is water, sediment and space. We divide the evolution phases which is formation phase, autumn phase and contabescence phase. In the end we confirms its main functions, which is discharging the folium water on the tidal flat of the Tidal-Basin in the end of the ebb-tide, transporting sediment to Tidal-Basin through tidal creek systems, confining the swing range of the dynamical axis of flood tide or ebb tide, balancing the dynamical status of the South and North. At the same time, we compare coastal tidal-basin and sandbanks tidal-basin on geomorphology characters, formation causes, style and so on.

条子泥潮盆—潮沟系统的基本地貌结构为分水滩脊和潮沟系统，本文分别对它们的形成与发育、地貌特点及动态变化进行了分析，并探讨了影响其发育的主要因素，即来水条件、来沙条件、空间条件，划定了其主要发育阶段，即形成期、成熟期、衰亡期；在上述分析的基础上确定了潮盆—潮沟系统的主要功能，即通过潮沟系统渲泄落潮后期滞留在其潮盆范围内的滩面薄层水、通过潮沟系向潮盆内部输入或输出泥沙、限制涨落潮动力主轴摆动范围、平衡南北两侧动力状态；同时针对岸滩潮盆—潮沟系统与沙洲潮盆—潮沟系统的地貌特征、成因类型等进行了对比分析。

The study results estimated that an acre of eelgrass is worth $1065 per year, an acre of saltmarsh is worth $338 per year, and an acre of intertidal mudflat is worth $68 per year, in terms of increased productivity of crabs, scallops, clams, birds, and waterfowl.

研究结果估计，一亩鳗草的英亩是一年价值$1065 ，一亩盐沼的英亩是一年价值$338 ，而且一亩涨落潮之间泥滩的英亩每一年是值$68，根据螃蟹，扇贝，蛤，鸟和 waterfowl 的增加生产力。

On the basis of previous study on deep channel, the South Branch,Xinqiao Channel,Nanxiaohong and Main Channel of Nangarg are chosen as the typical flood and ebb channels. Field data sampled in the flood season of 2001 and the dry season of 2003 are used as the base of the analysis of hydrodynamic characteristics, such as current, sediment, dominant current and dominant sediment.

在前人对河口冲刷槽研究的基础上，选择长江口南支、新桥水道、南小泓和南港主槽作为典型涨、落潮槽研究对象，以2001年洪季和2003年枯季实测资料为根据，比较分析了长江口涨落潮槽的水流、泥沙、优势流和优势沙等动力特征，结果表明用单一因子分析河槽性质不够全面。

At East Chongming tidal flat,the accumulation of labile organic matter was controlled by hydrodynamic condition.

而在崇明东滩，易变有机质的累积受水动力条件的绝对控制，不同地貌类型和生境对涨落潮有很大的作用，并影响表层生物生长，最终形成有机质生物化学组分分布的生境异质性。

The action of the third factor becomes active in slack water when the current velocity is low, and more remarkable in the surfer layer than in the lower layer near the bed.

其中第二个因素起主导作用，大潮期比小潮期显著，第三个因素的作用主要发生在涨落憩前后低流速期，并在表层较近底层的水体明显。

In the method, the factors, such as the tide bore variations, swift current at tide ebb and flow, severe changes of muddy riverbed, and details of design and fabrication of the steel cofferdams are considered.

介绍国内某大跨径桥梁深水大体积承台围堰的施工方法，该钢围堰的施工考虑了涌潮变化、涨落潮流速大、淤泥质地状况的河床剧烈变化，以及围堰设计、制作安装。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
