The traditional bubblefrequency correlation to estimate regular channel could not be used to predict the narrow channels.
根据常规通道内的经验计算公式，不能很好地描述窄流道中的汽泡频率特性。

The results show that bubblefrequency and gas holdup distributed highly surrounding the blade and uniformly in rest of the bath.
结果表明，气泡频率和含气率在喷头附近分布很高，在其它部位分布是均匀的。

The influences of wall on the frequency response of the bubble and the turbulent intensity of the bubble motion have been analyzed through frequency spectrum analysis method.
