froth layers是什么意思

用法例句

The settling velocities of galena,titanomagnetite and pyrite in the froth layers are determined,and the effects of the particle size and the surface hydrophobicity on the settling velocity in the froth layers are investigated.

试验测定方铅矿、钛磁铁矿、黄铁矿颗粒在泡沫层中的沉降速度,分析研究粒度及表面疏水性对颗粒在泡沫层中沉降速度的影响。

The pressure drop, froth height, gas holdup and entrainment have been measured.

根据板压降、泡沫层高度、泡沫层平均气含率、雾沫夹带随气体流量变化的趋势,得出如下结论:在相同的气速下,随着黏度增加,塔板压降降低,泡沫层高度降低;距测试筛板同一高度的雾沫夹带量随气量的增大而增加,随黏度增大而降低;雾沫分离空间相同时,雾沫夹带量随黏度增加而增大。
