抽水

For a given virtual small -scale grid system, an operating scheme for a wind powered pump storage system has been proposed; and the economic analysis model to maximize utilization of wind power is then developed.

将该联合运行系统与普通风电系统进行比较计算，结果表明：风电-抽水蓄能联合运行系统是最大化开发利用风能资源的有效途径，具有可观的经济效益和社会效益。

Both fountains were going furiously and both pumps bailing with might and main.

两个人的口水只管喷泉似地朝外涌，两个抽水机全力以赴往外抽水。

According to the engineering practice, the theoretical basis and method that survey directly the horizontal distance and height difference by the total station system as fourth grade and below fourth grade control network are put forward instead of surveying slant distance and zenith distance.

摘要根据工程实践，提出了用全站仪直接测量平距、高差来代替测斜距、天顶距作四等及四等以下控制网测量的理论依据和方法，并以张河湾抽水蓄能电站施工控制网为例进行了比较计算。

Too much pumping forced the authorities in the early 1990s to switch water licences to the Murray, 10km away at Alexandrina, one of two lakes at the mouth facing the Southern Ocean.

然而过多的抽水行为迫使当局于20世纪90年代初颁布了对距离亚历山德里娜湖10公里的墨累河水的使用许可证。

This paper discusses some problems that have more differences in the standard execution and presents the point that we should properly adjust the project scale and structure grade of the project under construction according to the new standard in order to upgrade the design; analyzes the project classification of the project extension and project to be constructed in phases, and classific...

为此，对该标准执行中存在较多分歧的一些问题进行了探讨，提出根据新标准适时调整在建工程的工程等别和建筑物级别以利于优化设计，对扩机工程和分期建设工程的工程等级划分、大型水电站的挡水和泄水建筑物级别的确定、抽水蓄能电站大坝的洪水设计标准等进行了分析。

First, spice up the woman on her back position by participating in the pumping, the gyrating and all that coital hip movement that comes with this sexual position.

首先，香料了该名女子对她的立场，回到通过参加在抽水， gyrating和所有性交髋关节运动，随之而来的，这性的立场。

Based on hydrogeological data and groundwater chemical analysis data and the theory and methodologies of groundwater chemical dynamics in combination with limited pumping test data, some groundwater chemical index such as activity of component、mineral saturation index are calculated and some hydrogeological parameters such as hydraulic conductively,transmissibility,artual speed of groundwater、specific velocity and groundwater age are also calculated zonally.The above calculation results are beneficial to quantificationally recognize the local hydrogeological conditions and to attest that the confined aquifer of Taconic formation has good permeability and transmissibility and t good renewal ability because of the active groundwater movement.

依据已有水文地质和水质分析资料，运用地下水化学动力学理论和方法，通过水化学指标（组分活度α、矿物饱和指数β）的计算分析，结合有限的抽水试验资料，分区计算出渗透系数K、导水系数T、地下水实际流速U、渗透速度V和地下水年龄t等5项水文地质参数，定量的认识水文地质条件，认证了水源地泰康组承压含水层具有渗透性强、导水性强、地下水循环交替快、可更新能力强等特点。

In order to solve the problems of dewatering and hydraulic connection among the multi-aquifer system in the excavation of the pits of the Dasi deep well gate and the lock gate,pumping tests were conducted in the field and the characteristics of groundwater transport in the ③_2 and ⑤ find sands were analyzed.

为了解决大寺深孔闸、船闸基坑开挖时的降排水工作及多层含水层的相互联通关系，我们进行了现场抽水试验，查明了拟建场地地基土③2层极细砂和⑤层极细砂的地下水运移特征，提出了基坑开挖应采取的排水措施。

The well point should pump water continually, the normal pumping rule is "big then small, feculent then clear".

井点应连续不断的抽水，正常出水规律为&先大后小，先混后清&。

Any skatepark needs flat bottom between obstacles, since skateboarders generate speed by pumping up and down transitions; maximum flatbottom allows more skateboarders to skate at the same time without collisions.

任何skatepark需要平底之间的障碍，因为速度滑冰一族产生的抽水向上和向下过渡；最高flatbottom允许有更多的冰刀滑冰一族，以在同一时间没有碰撞。

We will see more and more activist government policies that distinguish economic activities according to the nationality of the actors.

我们将看到越来越多激进的政府政策，这些政策根据企业的国籍来区分经济活动。

If we can prove the independence of an axiomatic system, then we can guarantee the conciseness of this system, ie.

如果能够证明某个一阶谓词系统的独立性，那么就能够保证该系统的建立是精炼的，即没有任何一条公理或推理规则是多余的。
