摘要
在一维有限振幅驻波声场中观察到了分岔现象。除了理论所预期的高次谐波存在外，次谐波、分数谐波亦存在于有限振幅驻波声场中。随基波声压级提高，最终达到混饨状态。
The phenomena of bifurcation have been observed in experiments on one-dimensional finiteamplitude staiding wave. Besides higher harmonics predicted according to the theory, subharmonics and fractional harmonics also aPPear in the finite--amplitude standing wave field, as the sound pressure gets higher, and eventually a chaotic state is reached.
