| 摘 要： | 通过理论分析得出管道内固液混合物运动的基本方程——连续方程、动量方程和机械能量方程，此基本方程可作为推导国波混合物管道阻力损失计算公式及离心泵输送固液混合物时扬程等计算公式的基本公式，并指出管道内单相清水的运动可作为固液混合物运动的特例。

| Abstract: | By theoretical analysis,it is proved that the equation of solid and liquid state admixture movement inside the pipeline has three forms: continuous equation,momentum equation and the mechanical energetic equation. The equation can deduce a formula to calculate the loss of resistance,the lift of centrifugal pump in carrying the admixture. It is concluded that the movement of one-way clean water is a special example of the movement of the solidly liquid admixture. |
