通气率 meaning in Chinese

ventilation rate

At the same time the number of holes for liquid flowing , gas flowing and blocked to the number of total holes was defined as liquid flowing ratio , gas flowing ratio and blocked ratio . the experiment was made with in - diameter 500mm column using water - air system , the ratio was first delected in detail by multi - path conductivity gauge for the compound tray with free area 20 % and 25 % respectively
采用多路电导测试仪，在直径500mm的冷模塔内，以空气-水为介质，首次较系统地测量了开孔率为20和25的复合塔板的通气、通液和阻塞筛孔的数量比例，获得了通气率、通液率和阻塞率随气液变化的基本规律。
