Theequivalence percolation resistance law is accurate enough to be used in productivitycalculation of horizontal well pattern.(3) Productivity of mixed well pattern of horizontalwell or multilateral horizontal well and vertical well is constructed and formulae are simpleenough to be used in the oilfield. The patterns include 5-spot pattern,7-spot pattern and9-spot pattern.(4) Productivity formula of united rectangular well pattern of horizontaland vertical wells is constructed. By this formula, the calculation results show that fora horizontal well length, there is a shape factor at which the productivity of the patternis biggest. So optimum method of the well pattern is proposed.(5) A new concept ofdimensionless length of horizontal well is advanced and the relationship of optimum shapefactor of the rectangular well pattern against dimensionless length of horizontal well ispresented. The influences of length of the horizontal well, area of the well pattern unitand the thickness of reservior are concerned.

So the effect of pollution improvement is affected, at the same time investment benefit is not fully made well. Aiming at the above problems occurred during the improvement of water environment pollution, based on the general analysis of current water environment pollution situation and cause of pollution by the instance of the water environmental pollution improvement in the centre town of Chengdu City, the article puts forward the reasons of water environment pollution of most cities: wastewater collection is insufficient because of delaying of pipe net construction; capability of sewage treatment is inadequate; manage measure is not regular because of management not according to laws and laws not strictly executed; investment channels of pollution implement is unitary.

通过对成都市中心城水环境治理实施方案的研究，对如何与城市建设相结合来进行水环境污染治理提出以下几点看法：①应合理划分流经城市水体的功能区域和正确确定水环境治理目标一些设想；②必须有科学、合理、全面、可操作性强的城市排水规划；③建设、完善污水收集系统，提高污水收集率，加快城市污水处理厂建设，提高污水处理能力；④对中心城河道按防洪、截污、环卫、绿化、景观的要求进行全面整治；⑤治污资金的筹措应从单一的政府投资模式向多元化的融资渠道发展；⑥制定、完善相应的法律、法规、制度以及工程建设管理措施。

The research work done is presented as follows:Compound dewatering technique of vacuum tube well is an effective technology for solving the dewatering problems of aquitard and interface relict water according to physical simulation test and field test. The variation laws, such as degree of vacuum, pore water pressure in different strata, have been studied. The results show that there is a certain scope of influence of vacuum in strata, and the vacuum degree in the horizontal direction decreases gradually with the increase of the distance from the main well; the change law of degree of vacuum in the vertical direction increases firstly and then decreases with the depth of soil strata, and changes with different soil nature and depth; changes of pore water pressure in soil strata has also shown a similar law of degree of vacuum.

主要研究工作如下：通过室内物理模拟试验和现场试验均证明了真空管井复合降水技术用于解决弱透水层和界面残留水疏干难题的有效性；并且对不同地层中真空度、孔隙水压力等变化规律进行了研究，发现地层中真空度均有一定的影响范围，且真空度在水平方向上随距主井距离的增加而逐渐降低；在垂直方向上真空度随深度总的规律是先增加后降低，并随土层性质及深度的不同而变化；土层内孔隙水压力也呈现出与真空度类似的变化规律。

The water storage function of condenser is the must not only for gathering and storing condensed water, various water repellence of thermal system, exhaust steam and chemical feedwater, but also for cushioning dramatically changing turboset flow during the operation, improving the stability of system regulation and ensuring the essential water-absorption pressure head of condensation pump.

凝汽器的蓄水作用既是汇集和贮存凝结水、热力系统中的各种疏水、排汽和化学补给水的需要，也是缓冲运行中机组流量急剧变化、提高系统调节稳定性的需要，并且是确保凝结水泵必要的吸水压头的需要。

There was a water pool not far away from his house. My friend told me it was in fact a part of the reservior nearby.

在他的住所不远的地方有一片水洼，朋友告诉我实际上那就是附近那个水库的一部分，只有在雨季，水库里的水才通过一条地下管道流到这个洼地，于是，随着水的到来，成千上万的青蛙也跟着来了。

A fox had fallen into a well, and had been casting about for a long time how he should get out again, when at length a goat came to the place, and wanting to drink, asked Reynard whether the water was good, and of there was plenty of it .

一只狐狸掉在一口井里，转了很久怎样再跳上去，最后一只山羊来到这里，他正想喝水，便问狐狸这水好不好，还多不多，狐狸掩饰起他的真实危险处境，回答说："下来吧，我的朋友，这水好得使我喝不够，而且多的用不完。"

A fox had fallen into a well, and had been casting about for a long time how he should get out again, when at length a goat came to the place, and wanting to drink, asked Reynard whether the water was good, and of there was plenty of it .The fox, dissembling the real danger of his case, replied :"comedown, my friend, the water is so good that I can not drink enough of it, and so aboundant that it can not be exhausted ."
