The effects on solids holdup of heat exchanger tube, bed height, static pressure drop and average solids holdup of inlet chamber by superficial velocity were studied in different main distributors.

在不同结构形式的主分布器条件下，研究了表观液速对换热管中固含率、下管箱内床层高度、静压降及平均固含率的影响。

In a fluidised bed a fluid is passed through a bed of particulate solids at a velocity sufficient to provide an upward force equal to the weight of the particles, therefore buoying the particles.

在流化床中，流体通过固体颗粒床层，其流速足够产生一个与颗粒重量相等的向上的力。因此而使颗粒悬浮。
