摘　　要：根据φ１５瓷拉西环填料在不同高径比时体动持液量的实验值和优化计算方法，得出含有高径比参数的体动持液量计算经验关联式，由此关联式推得算出泛点气速．并简要分析了泛点气速变化引起泛点体动持液量变化与高径比的关系．According to the experimental values of voluminal operating hold up for the cermic Raschig ring packing with 0.015m in diameter,under different height to diameter ratioes and by the optimal calculating method, the empirical calculating correlation of voluminal operating hold up with parameters of height to diameter ratioes has been obtained. From this correlation,the flooding velocity has been deduced. And this paper analyses briefly the relationship between the change of voluminal operating holdup at flooding point caused by the change of flooding velocity and the height to diameter ratioes.
