摘　　要：讨论了预测热声装置频率和波长数的意义和方法 ,给出了双边气库型和混合气库型热声装置的频率和波长数的计算结果 。The fluid impedance method to calculate the resonance frequency and the wavelength number of thermoacoustic engines is introduced,and it is predicted that the hybrid arrangement has lower frequency than that of the double arrangement.Study on the wavelength number is instructive.Finally,the experimental results are given which verify our predication.
