In both the general arrangement and the determination of the size of drop fall, it should be considered to generate electric energy as much as possible in order to make full use of water resources, on the premise of meeting needs of irrigation. If pump stations are installed in such systems, great effect on saving energy will be produced. In this paper, the problem of dividing a river into stages is also discussed.             本文讨论灌溉发电系统的合理规划问题.无论在总体布置中,还是在决定跌水高差时,均在满足灌溉要求的同时,做到尽可能多发电能,充分利用水资源.灌溉发电系统中加入抽水站,有明显的节能效果.文中还讨论了灌溉发电系统的划分梯级问题. 文摘来源          This paper deals with the preliminary experimental study of drag reduction by adding minute quantity of polyacrylamide, a water-soluble longchain high molecular polymer, into tube flow of clear water and muddy water. Tests were performed in two tubes of inside diameters of 0.682 and 0.798 cm respectively. The mean grain diameters d_(50) of suspended sediment are 0.0052 and 0.0185 mm respectively. The consistency of polymer in the flow is 5-100 ppm. Data measured from tests in clear water agrees with von Ka...             本文简述了在特制装置内,对清水及浑水管流中添加微量水溶性长链型高分子聚合物聚丙烯酰胺的方法来降低摩阻损失进行了初步试验研究。关于聚合物减阻的理论及试验研究是一个相当广泛而又重要的课题。文中首先介绍了清水聚合物流减阻条件、阻力变化规律及减阻效果与流速及聚合物浓度的关系,并提出清水聚合物流阻力表达式(4),该式与试验结果大体相符;继而着重介绍了浑水聚合物流减阻效应,并讨论了减阻效果与流速、聚合物浓度、悬沙粒径及浑水浓度等基本参数之间的关系。浑水聚合物流不但使阻力大幅度下降,同时临界流速也显著减小,从而改善了浑水流动特性和经济指标。对泥沙长距离输送、充分利用水沙资源有很大意义。 文摘来源          This is the summary of four state-of-the art reports, i. e. the treatments of soft foundations, new techniques in soft foundation treatments, concrete cutoffs and sand-gravel grouting. These reports were presented at the Symposiun on the Treatments of Soft Foundations of Large Dams, held at Wugong, Shaanxi (Oct., 1982), organized by The Committee on Engineering Construction, Chinese Society of Hydraulic Engineering. The soft foundation discussed here is referred to the alluvial plain, alluvial layer and swa...             本文介绍了中国水利学会施工专业委员会大坝软基处理学术讨论会(1982年10月,武功)的四个专题报告,即:软土地基处理;软基处理新技术;混凝土防渗墙基础处理;砂砾石灌浆。这次提到的软基是指冲积平原、冲积层、沼泽地未受地质变化,未受荷载和震动等物理作用的地基。建国三十多年来,随着水利水电事业大规模兴起,在软土地基上修建了不少涵闸和堤坝,基础处理技术也因此得到迅速发展,积累了实践经验,取得了成绩。 文摘来源   << 更多相关文摘         相关查询: oceanic resources resources of substitute resources agent resources resources overlapping creatures resources resources position shortage resources nonstandard resources driving resources berberis resources construction resources  对查询结果不满意
