measurement of amplitude modulation and dispersive effect of nonlinear resonant oscillations

利用该换能器对谐振柱面波的色散效应进行了测量。通过实验发现了气体共振振荡的色散效应对振幅的调制作用。共振波的空间分布由共振器中的粒子观察到。实验结果表明，色散效应与振幅调制有关。由于调制的周期与理论和数值分析的结果一致，因此实验表明了声场几何形状引起的色散效应的存在。

Measurement of dispersion effect of resonant cylindrical waves is performed by using the cylindrical transducer. The amplitude modulation due to the dispersive effect of the resonant gas oscillations was found through the experiment. Spatial distribution of the resonant wave was observed by the particle in the resonator. The experiment revealed that the dispersion effect associated with the amplitude modulations. Since the period of the modulation is consistent with the results of both theoretical and numerical analysis, the presence of the dispersion effect resulting from the geometry of the sound field was shown experimentally.
