抽水

Spalling step by step as the essential mechanism of Karst collapse induced by pumping is put forward.

提出了抽水引起岩溶塌陷的逐层剥落机理，将以往的岩溶塌陷机理辩证地统一起来。

As this was a time when every Body had his own Life to think of, no body minded me, or what was become of me; but another Man stept up the Pump, and thrusting me aside with his Foot, let me lye, thinking I had been dead; and it was a great while before I came to my self.

这种时候，人人都只顾自己的生命，那里还会有人来管我死活，也没有人会看一下我到底发生了什么事。另一个人立刻上来接替我抽水；他上来时把我一脚踢到一边，由我躺在那里。他一定以为我已经死了。过了好一会儿我才苏醒过来。

Some problems in designing trashrack of pumped-storage hydroplants in Japan and USA.

日本、美国设计抽水蓄能电站拦污栅中的几个问题。

Hydraulic model test was carried out to study the velocity distribution behind the trashrack in lateral intake/outlet of a typical pumped storage power station.

本文以某抽水蓄能电站上水库进/出水口为例，通过水工模型试验，研究了侧式进/出水口拦污栅断面的流速分布规律，着重分析了扩散段隔墩布置型式与过渡段体型对拦污栅断面流速分布的影响。

The hydraulic characteristicswas studied by the whole experimentation of the intake/outlet. Currently, the trashrack is not simulated because of the model reduced scale, and thought it couldn'teffect on the experimentation.

由于进/出水口的水力特性非常复杂，且国内外的参考实例较少，有必要对抽水蓄能电站进/出水口拦污栅的水力特性作深入分析和比较。

They warn people, for example, against chewing gum, littering, eating or drinking in a bus or train, damaging flowers, trees or other plants, spitting, and leaving the toilet unflushed after using it.

提醒人们不能吃香口胶、不可乱丢垃圾、不得在公共汽车和地铁车厢里吃东西、不可随意摘花草树木、不能随地吐痰、上厕所不忘抽水等等。

They warn people, for example, against littering, spitting, chewing gum, eating or drinking in a bus or train, damaging flowers, trees or other plants, and leaving the toilet unflushed after using it.

提醒人们不能吃香口胶、不可乱丢垃圾、不得在公共汽车和地铁车厢里吃东西、不可随意摘花草树木、不能随地吐痰、上厕所不忘抽水等等。

In this paper, back to back starting and static frequency convertor starting of pumped storage motor-generator are studied. A computer simulation method, which is more close to practice taking into account effect of mechanical torque developed by the turbine, opposing torque of the unwatered runner of motor, transformer and transmission line is adopted.

本文对抽水蓄能电动发电机组两种常用的启动方式：背靠背启动、静止变频器启动进行了研究，从工程实际出发，考虑了水轮机输入转矩、水泵阻转矩曲线，及线路、变压器等参数的影响，进行启动过程的计算机仿真计算，对影响启动过程的重要因素进行了深入分析，得到了一些重要结论。

Pre-washing the stones can help with a clean install or you can hose them down in the pond while pumping out the dirty water.

预洗石头可以帮助一个清洁，安装或者，你可以软管他们失望了，在池塘，而抽水出脏水。

Where ground water is encountered, it shall be kept below the pipe by means of pumping until the pipe has been satisfactorily tested and backfilled.

如地下水中遇到的，它应保持低于管的方式抽水，直到管道已得到令人满意的测试，并回填。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
