The optimization system of water supply networks is very complicated. It deals with lots of factors from the process of networks' modeling, node demand calculation, initial flow distribution, and the optimal design to the drawing of pipe networks and isopiestic line. The total effect will be better if amelioration is imposed on each part of these processes.

After investigation, simulation test, research and analysis , the results of which show that the wool lipoid isn't suitable to he used to the ballast tank with sea water higher than 50℃ and similar condition; Residua rust and water on the surface to be coated shall be controlled strictly.

经勘查、测试、模拟试验、研究分析认为：该羊毛脂涂料不适于在50℃以上的海水压载舱及相似环境下使用；在带锈施涂中应严格控制涂装表面的残留锈层和水分。

In an extreme case, the porewater pressure may become so high that many of the soil particles lose contact with each other.

在极端的情况下，孔隙水压会增大到导致许多土壤颗粒相互之间失去接触的程度。

It is a new vacuum mair pump,which can provide with circulating water to the reaction of device at same time.

同时还能向反应装置中提供循环冷却水，特别是在水压不足和缺水源的试验室更显之优越。

The front also cools the melt as it is pushed down the mold cavity by water pressure.

在水压的作用下，水流前沿向型腔内流动的同时也对塑料进行冷却。

The maj or obj ect of this paper is the medium.small size concrete dams that have been used for many years.They have the characteristic that the alteration of water height of reservoirs is unobvious and the dams, displacements are affected mainly by temperature.With a case,the method of stepwise regression is used to analyze the vertical displacement prototyDe observed data.Then regression equation is established,the relation of dam,s displacement with hydraulic pressure、temperature、time effect is analyzed and the displacement change rule is obtained,the dam'S displacement onlv dependent to temperature is received.According to the theory of Finite Elements Method,the quasi-stationary temperature field formula and temperature stress formula are deduced.The QTP program and TFEM3D program are written with FORTRAN.The same case is calculated through QTP program to solve the quasi-stationary temperature and through TFEM3 D program to solve the dam'S displacement and find tlle dam,s deformation rule.This rule is accordant with the regression,S resuIt.

本文主要针对运行期间库水位变化很小、坝体的位移主要受温度变化影响的中小型混凝土坝，结合工程实例，采用逐步回归的方法对垂直位移原型观测资料进行分析，建立回归方程，分析坝体位移与水压、温度、时效之间的关系以及位移变化规律，分析结果坝体位移只与温度有关，而基本上不受库水位变化和时效的影响；根据有限元原理推求了混凝土坝准稳定温度场公式和温度应力公式，利用FORTRAN语言编制出QTP准稳定温度场程序和TFEM3D位移场程序，对大坝的温度场和位移场进行计算，求出坝体结点的变温值和坝体结点位移值以及单元应力分量，分析得到大坝的变形规律与实测资料以及回归统计变形规律一致，说明对坝体准稳定温度场的研究是正确的。

The water pressure that you get down at 3,000 feet is mind-boggling.
