查询词典 depth of water

The first kind is 0-equation model. It only includes mass and momentum conservation equations. Great progresses have been made in improving this model. It has successfully been applied to many natural rivers with complicated boundary geometry. The second kind is κ-ε model. The κ equation and ε equation are needed, besides mass and momentum conservation equations. Many researchers have studied the depth-averaged mathematical models of turbulence in recent years. However, the models were used mostly in regular artificial canals or natural water areas with simple boundaries.

对于宽浅型河流，采用深度平均法进行流场计算时，用得较多的有两类模型：一类是不增加任何脉动量的偏微分方程的模型，这类模型已在适体坐标下运用得较多且较成功；另一类是κ-ε二方程模型，它是近几十年来广泛应用的一类湍流模型，并发展了许多具体的形式，但大多数只对顺直河道进行了研究，对弯曲较大的河道研究不多，本文运用适体坐标，采用正交交错网格及非正交交错网格，把此模型运用到了弯曲较大的河段及具有汇流的河段，取得了较大的成功。

The submergible control platform width was positively related with the diameter of cage framework. The relation was k=1-2+22r-h_4~2+14l~2+12r~2-22rl, in formula h_4 was the platform height, which was restricted by the water depth. There h=h_1+h_2+h_3+2h_4+12H, in equation h_1 stood for net sheepshank height, h_2, the height of gravity setting on the bottom net, h_3, the distance from gravity setting to submarine, H was estimated maximal wave height while typhoon occurred in cage areas.

控制平台的宽度l与网箱主构架半径r正相关，设计时必须满足网箱框架外侧与平台的距离k大于零，其中：k=1-2+22r-h42+14l2+12r2-22rl，h4为控制平台高度，其受放置区水深h的制约，高度与水深的关系：h=h1+h2+h3+2h4+12H，h1为网衣缩结高度，h2为网衣底部重力装置高度，h3为重力装置到水底的距离，H为网箱放置区台风期预计最大波高。

There are three kinds of fluid muds according to the dynamic conditions. The first one was formed at slack water during flood and ebb tides with a large scale but small thickness. The second was formed at area of grows saltwater wedge with small scale and thick depth.

在成因类型上分为憩流浮泥、盐水楔浮泥和风暴潮浮泥，第1种在涨或落潮转流期低流时形成，规模大，厚度薄；第2种在盐水楔发育时形成，规模较小，厚度较大；第3种在大风后形成，规模大，范围广；若三者相遇，则浮泥厚度和范围最大。
