froth height meaning in Chinese

泡沫高度

The residence time of distribution and froth height in the downcomer were measured . the tracer used was 10 wt % sodium chloride solution . the residence time of distribution curves in a downcomer were measured by using the tracer technique
所用示踪剂是10 (质量百分比)的nacl溶液， rtd曲线采用了脉冲响应技术来测量，用计算机实时采集系统对数据进行采集。
The effect of gas rates , liquid flow - rates , downcomer width , weir height and the addition of surface active agent on the liquid mean residence time , t , effective diffusion coefficient , de , and froth height , hf were studied . results obtained showed that for two systems , the t in the downcomer of ctst plate is 20 - 50 % smaller than that of fl valve plate , and the de is 40 - 70 % smaller than that of fl valve plate
通过对气速、液体流量、降液管宽度、堰高和表面活性剂加入的影响进行分析得出下面结论：在相同的操作条件下，对于两种物系， ctst塔板降液管的液体停留时间比f1浮阀塔板的约小20 50 ，有效扩散系数比f1浮阀塔板的小40 70 ，泡沫高度低110 150mm 。
