  1. On the basis of research results of the existing experts and scholars especially the theory put forward by professor xu zhenliang ( my tutor ) that predicts the velocity profiles and friction loss of settling slurry when it flows in horizontal pipe and upward - inclined - pipe, relations among the velocity of water, that of solid particles and that of settling slurry have been established by the analysis of momentum transmission process between water and solid. then the calculation formulae for fricton loss of downward inclined and vertical pipe are deprived

    本文在現有專者的研究成果特別是許振良教授(導師)提出的預非均質流在平管及向上傾斜管流動時的速度分佈及摩阻損失的理論的基礎上,從動守恆的角度建立了清速度、固體顆粒速度和漿體速度之間的關系,進而推導出了向下傾斜及垂直管沉降性漿體輸送的摩阻損失的計算公式。
