Some, perhaps, may simply be intercepting water for one user that would otherwise have gone to another, but almost every country could reduce its evaporation losses by capturing water and delivering it more effectively to the farmer, bather, drinker or manufacturer—and then, ideally, using it again.
有些国家也许只是出于自私的目的将水拦截,不让水流向其他国家,但几乎每一个国家都可以通过集水和提高输水效率的办法减少水的蒸发损失,使水能够高效地用于灌溉、洗浴、饮用及制造产品,更理想的是,能够循环利用这些水资源。

Nowadays the single tube and single-unit hydroelectric station have been used widely and skillfully, but it is necessary for some large hydropower stations to use tailrace bifurcated tubes, just as Xiaolangdi, Xiangjiaba, Baishe project and so on. So it is significant to study the transients of long tailrace tunnel with tank or without tank.
对于尾水系统,单管单机的布置方式比较成熟,尾水岔管的布置方式目前在大型电站中用的较多,如小浪底、向家坝、百色等,因而研究其在有尾水调压井和无尾水调压井的情况下的过渡过程,很有实用意义。

In this work, nanostructure samples of La1-xCaxMnO3(x=0.2、0.3、0.4、0.5)were prepared by hydrothermal-precipitation method . The structural characterization of the powder samples were done by X-ray diffraction. XRD patterns showed that all the samples ate single perovskite-type phase withoutother impurity or secondary phase. The shape and size of samples were performed on Scanning Electron Microscopy. SEM photographs investigated that temperature of hydrothermal effects the phase of samples and alkalinity of the reaction mixture by ΔTad-T curve measurement device at low magnetic fielded
本论文采用水热共沉淀退火法制备了La1-xCaxMnO3(x=0.2、0.3、0.4、0.5)系纳米结构,用X射线衍射仪确定产物为单相钙钛矿结构,无任何杂峰及第二相;用扫描电子显微镜与透射电子显微镜分析了产物的大小和形貌,发现水热温度对产物的形成起决定作用,随着温度的升高,产物由薄膜状向丝状转变,而溶液的碱度可控制产物的形貌和大小,当碱度为6.35mol/L,水热温度为240 C时,La0.6Ca0.4MnO3的主要形貌为纳米丝并有少量纳米颗粒,纳米丝平均直径为40nm;最后测量了粉末样品在低磁场(1.4T)下的磁热效应,发现水热共沉淀退火法制备样品的最大绝热温度明显高于球磨法制备样品的最大绝热温变。

Also the multi-scale entropy processing and analysis of conductance fluctuating signals acquired by VMEA sensor for five flow patterns with water as the continuous liquid are conducted. The study result indicates that the increase of f o makes oil in water type slug flow occur at lower U sg; for low flow velocity, the continuous liquid inversion occurs at about f o=0.9 and the increase of U sg makes the inversion point move to low oil volume fraction; the multi-scale entropy detail describes the nonlinear dynamic characteristics of oil-gas-water flow patterns and the rate of MSE at low scales sensitively indicates the variation of flow patterns and can act as the efficient criterion of three-phase flow patterns identification.
