超声毛细效应的探究

Exploration of ultrasonic capillary effect

通过对超声波泵现象进行预实验,判断出毛细管内液面反常上升的高度与毛细管、液体和超声波的诸多性质相关.从挤压模效应和空化效应分别对超声毛细效应进行理论分析,判断出了影响超声波作用下毛细管内液面反常上升的因素,并通过实验测量结果验证了此理论的自洽性.

Through the pre-experimental conjecture of ultrasonic pump phenomenon,it was estimated that the height of the abnormal rise of the liquid level in capillary was relevant to quite a few properties of the capillary,liquid and ultrasonic wave.Based on the theoretical analysis of ultrasonic capillary effect from the extrusion mold effect and the cavitation effect,the factors affecting the abnormal rise of the liquid level in the capillary under the action of ultrasonic wave were demonstrated,and the experiment results confirmed the self-consistency of the theory.
