1.The leaves clog our drains in the Fall; The water pipe is backed up.
秋天树叶堵塞了我们的排水沟。收藏指正
2.The selection of pipe wall thickness,the calculation and design key points of the melt flow,melt pipe flow pressure fall and melt flow speed in the design of melt pipes were introduced in detail.
介绍了熔体管道设计中管道壁厚选择、熔体流量、熔体管道流动压力降和熔体流速等计算方法和设计要点。收藏指正
3.The research result demonstrates that along with the increment of Reynolds number, the root mean square value of outer fluctuating magnitude of the external diameter in fall frequency band increases, the root mean square value of fluctuating magnitude of the external diameter in high frequency band decreses, demonstrating that the fluctuation of flexible pipe wall changes fluctuation don field of original rigid pipe, large-size eddy motion increases and small-size eddy motion decreases, this reduces energy loss and increases friction reduction effectiveness.
研究结果表明：随着雷诺数的增加，全频带的外径脉动的均方根值加大，但高频带外径脉动的均方根值减小，说明柔性管管壁脉动确实改变了原刚性管的脉动流场，大尺度涡的运动加剧，低尺度涡运动减弱，从而使得能量损失减少，减阻效果增大。收藏指正
4.And the pressure fall along the line is calculated by the Dukler-Eaton-Flanigan (DEF) model, that is to say, Eaton method to calculate water ratio, Dukler Ⅱmethod to calculate the pressure drop,Flanigan to calculate the additional pressure reduction caused by pipe accidents.
其中沿程压降的计算采用组合水力学模型(Dukler-Eaton-Flanigan),即用Eaton法计算截面含液率,用duklerⅡ法计算水平管路压降,用Flanigan法计算管路起伏的附加压降。收藏指正
5.Amelia Soares, spokeswoman for Harmony Gold Mining Co., said that despite the pipe fall itself and the long hours spent by miners waiting for rescue a mile below the surface, only one health problem was reported - a worker who had to be treated for dehydration.
和谐金矿公司的女方言人声称，尽管管道自身断裂矿工们在地下一英里处等待救援，但是只有发生一起安全问题－一个工人因为脱水需要得到救治。收藏指正
