  5. In order to know the relationship between gas - content and pipeline ' s pressure drop, the thesis deduces the pressure drop calculating equations based on uniform flow pattern and separating flow pattern. the equations show that pressure drop is made up of three parts, that is, friction resistance effect, gas acceleration effect and the gravity effect. and the research has shown that the gas has little effect on pressure drop. in the horizontal pipeline, the resistance effect must be overmatched the acceleration effect

    為探討加入的氣體對管道壓力的影響，本文基於分相流和均相流兩種模型分別推導了三相流管道的壓降公式，表明無論是分相流模型，還是均勻流模型，管道內流體總的壓降是由三項組成的，即摩擦項、加速項和重力項，並得出了加氣對管壓變化不大的結論，所以認為在水平管道中，要獲得有效的減阻，則要使摩擦阻力分量的減小效應大於漿體加氣的加速效應。
