摘　　要：分别用数值计算(FDTD)和实验方法给出了不同频率不同搅拌器配置情况下混波室功率密度的相关函数,并计算了相应的独立采样数,数值计算结果与实验结果吻合,表明了算法的有效性。所得结论为混波室搅拌器的设计提供了依据。The correlation function of power density distribution and the number of independent sample points in reverberation chamber are measured and calculated using finite-difference time-domain （FDTD） method for different stirrer configurations and frequency, respectively. There is good agreement between measured and computed results, which proves validity of the compute method. Design guidelines are provided for the design of stirrer of reverberation chamber.
