主要研究开口圆管内的非线性振荡。圆管受迫端由一活塞驱动，活塞为小谐波振荡，另一端为完全开口状态。理论和实验均发现存在非线性现象。实验中还发现活塞激振频率和管内气体的固有频率接近时会发生共振，有强烈的非线性效应。同时在管口附近产生强烈的整流效应。发现利用此效应对水流有较好的雾化功能。
The main study of non-linear oscillation within the open pipe. The forced end of the tube is driven by a piston, the piston oscillates with small harmonics and the other end is fully open. Both theory and experiment have found that there is nonlinear phenomenon. It is also found in the experiment that the resonance occurs when the excitation frequency of the piston approaches the natural frequency of the gas in the pipe and there is a strong nonlinear effect. At the same time in the nozzle near the strong rectification effect. Found that the use of this effect on the water flow better atomization function.
