In this paper the characteristics of hydraulic resistance of bamboo pipes which are widely used in temporary water supply systems in China are analyzed. By cutting away the diaphragm on the bamboo joints, the pipe is formed by the hollow stem of bamboo. It is indicated in this paper that the resistance of such a pipe is caused by the skin friction of the inner wall surface of the hollow stem and the form drag of the diaphragm remaining on every joint. Because the joints are numerous, the effect of the for...             本文阐明在我国临时性供水系统中广泛应用的竹管的水流阻力的特性。 经过把竹节处的隔膜铲除后，空心的竹杆构成管道。文中指出这种管道的水流阻力是由竹管的内壁的摩擦阻力和每小竹节的隔膜铲除后的残留部分绕流阻力组成的。因竹节数量很多，全部绕流阻力的效果与加强的摩擦阻力相似。所以总阻力可以表述为摩擦阻力并用摩擦阻力系数λ来表征。 根据大量的试验研究，我们找出阻力系数λ是雷诺数、管壁的相对粗糙、被铲除隔膜的残余部分的高度、竹节的间距以及管径的函数。为了管路的设计，文中给出了在平方阻力区内的阻力系数λ的公式和λ的经验数据。 文摘来源          The solution of karst aquifer flow by traditional method is rather difficult. Since the introduction cf the system theory, it makes new progress, This yields to the discrete-state compartment (DSC) model and the perfect mixing model (black box model). Both models are based upon the isotope content of environmental tritium in the karst aquifer to calculate the valuable hydrogeological parameters, such as average age of groundwater, rate of recharge, effective porosities and quantity of storage etc. These are...             岩溶含水层水流用传统方法求解通常是困难的,自从引入系统理论后,取得了新进展,产生了离散态混合模型和全混模型(黑箱模型),这两个模型根据岩溶含水层中环境同位素氚含量计算出有价值的水文地质参数,诸如地下水平均年龄、补给率、有效孔隙率和储存量等,并特别适用于岩溶管道水流。 文摘来源          According to the law of flow velocity distribution in penstock and by individually using the numerical integration methods of Gauss and Markov, the mathematical models for discharge calculation, path distribution coordinates and weight coefficient of multiple-path supersonic flow measurement in circular penstock are obtained, The measuring results of these models have been verified by the data got in field.             本文从分析压力管道水流流速分布规律出发,分别应用高斯和马尔科夫数值积分方法,得出了圆形管道多声路超声波测流流量计算、声道分布坐标及权重系数的数学模型,并用现场实测资料进行了验证。 文摘来源   << 更多相关文摘
