水流

The internal relations between average velocity of water flow and load weight is discussed when stuff canister moves incipiently.

以筒装料管道水力输送中料筒起动阶段为研究对象，研究料筒起动时承担输运任务的水流的平均流速与料筒荷重间的内在联系。

The article studies mostly the incipient motion process in tube-contained raw material hydraulic transportation. The internal relations between average velocity of water flow and load weight is discussed when stuff canister moves incipiently.

以筒装料管道水力输送中料筒起动阶段为研究对象，研究料筒起动时承担输运任务的水流的平均流速与料筒荷重间的内在联系。

The face of this protrusion defines an included angle to the upstream direction of less than or equal to 90 so that water flow thereat is deflected back on itself thereby increasing the local pressure on the first surface.

面对这一突定义了一个夹角的上游方向小于或等于90 ，使该处水流偏转是回到自己从而增加了地方压力，第一次面。

What little Wind there was blew me towards the Land; and thus, having found two or three broken Oars belonging to the Boat, and besides the Tools which were in the Chest, I found two Saws, an Axe, and a Hammer, and with this Cargo I put to Sea; For a Mile, or thereabouts, my Raft went very well, only that I found it drive a little distant from the Place where I had landed before, by which I perceiv'd that there was some Indraft of the Water, and consequently I hop'd to find some Creek or River there, which I might make use of as a Port to get to Land with my Cargo.

最初一海里，木排行驶相当稳当，但却稍稍偏离了我昨天登陆的地方。至此，我发现，原来这一带的水流直向岸边一个方向流去。因此，我想附近可能会有一条小溪或小河，果真如此的话，我就可驾木排进入港口卸货了。

The H value was calculated to be 0.246 using Shannon-Wiener diversity index method.By aquatic reservoir evaluation criteria, combined with the type and density of zooplankton,it could be clearly determined that the water quality was seriously polluted and eutrophic.4.Comprehensive assessment of water quality:Affected by the influxion of sewage, slow flow velocity,high contents of nitrogen and phosphorus,the quantities of both zooplankton and phytoplankton at 1st point were relatively high,with the appearance of various indicator species of water pollution.

计算Shannon-Wiener多样性指数法得出H值为0.246，通过水库水生生物评价标准，结合浮游动物种类和密度，可以很清楚判定水质为污染严重，已经呈富营养化。4水质综合评价：排污口1号采样点受生活污水的大量排入的影响，且水流流速缓慢，水中氮磷含量高，因而浮游动物和浮游藻类数量都很高，而且出现很多污染生物指示种，综合分析该水层水质属污染严重的富营养化。

The mild-slope equation with current effects is reformulated to an inhomogeneous Helmholtz equation. Applying the conventional boundary element method to this inhomogeneous equation, the inhomogeneous part will result in a domain integral which makes the computation complicated and messy. To improve this drawback, the DRBEM is adopted to transform the domain integral to boundary integral.

首先将含水流效应之缓坡方程式重新整理为非齐次之Helmholtz方程式，再利用Green公式改写为积分方程式，但利用一般传统边界元素法解析时，将存在一领域积分项，使得边界元素法显得繁杂且不完美，为改善此一缺陷，本文乃应用双互换边界元素法之技巧，以节省大量之数值计算时间。

Some infiltrated water may emerge to surface-water bodies as interflow , while other portions may become groundwater flow .

一些可能出现的水渗透到地表水体的交流，而其他部分可能成为地下水流。

When water speeds, air will intermingle water, and then the water-air twophase flow is being.

3当水流速度较高时，空气将掺入水体，形成水气两相流。

But due to recent rains, it's long been inundated by the water.

不过因为最近雨水很多，水流已经漫上来了。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
