摘　　要：本文采用以弹状气泡速度运动的相对坐标系,对液体段建立动量衡算关系,分析了弹状流压力降中加速压降的来源。与前人结果比较,理论根据较为充分,与实验数据也更为吻合。A referance coordinate system moving with the velocity of slug bubble is used to establish the momentum balance equation for a slug flow unit and to analyse the pressure drop due to the changes of the momentum. Compared with the precious worts,the method proposed is more acceptable in theoretical aspects,and the results predicted are in better agreement with the experimental data.
