摘要:

本实验通过观察火焰环燃烧的火苗分布,形象生动地展现了两列相向传播的波列在环内空间相干并形成驻波的情况。火苗的波峰和波谷数目随入射声波的频率改变而有规律的变化。



Abstract:

By observing the flame distribution of a burning flame ring, this experiment vividly shows the condition of the two oppositely travelling wave trains which cohere in the space of the ring and form standing waves, The number of wave crests and wave troughs of the flame varies regularly with the change of frequences of incoming Waves.
