The results showed that the solid holdup in the reactor was higher than that in feed, the pressure drop remained unchanged along the axial bed but was influenced by the content of solid in feed;
结果表明：反应器内固含率要高于进料中的固体含量；床层轴向压降保持不变，但受固相含量影响；

The strength analysis of a drop-shaped tube is resolved into the following problem: axial compression together with a plane state of strain with uniform internal pressure.
把滴形管的强度分析问题分解为：沿管轴线方向的压力问题与管沿周线方向均布压力的平面应变问题的叠加。

It has been found that the pressure drop of the distributor has little influence on the axial apparent solids concentration in upper dilute region and on the external circulation rate.
