AC=空腔内的声速D=空腔深度f=频率fn=预计峰值频率Kc=平均涡流对流速度与自由流流速度之比L=空腔长度L=D=空腔的长深比M1=自由流马赫数n=模数PREF=参考压力，2 10 5PaQ1=自由流动压r=温度恢复系数U1=自由流速度=空腔内涡流脱落和声波响应之间的相位常数=理想气体的比热比f=功率谱密度随频率引入的函数
ac = speed of sound inside the cavity D = cavity depth f = frequency fn = predicted peak frequency kc = ratio of the average vortex convection speed to the freestream flow speed L = cavity length L=D = length-to-depth ratio of the cavity M1 = freestream Mach number n = mode number pref = reference pressure, 2 10 5 Pa q1 = freestream dynamic pressure r = recovery factor in temperature U1 = freestream velocity = phase constant between vortex shedding and the acoustic wave response in the cavity = specific heat ratio of the ideal gas f = power spectral density as function of frequency Introduction
