| 摘 要： | 本文通过数值分析，对几个著名的地震记录的功率谱ARM解的特性作了讨论，并与高速富里衰变换（FFT）法的解进行了比较，讨论了ARM应用于各类地震记录的谱分析的适用性。比较结果表明：对于不同的地震记录，其功率谱的ARM解等价于按一定谱窗宽度平滑化的FFT法解。本研究还对赤池氏推荐的自相关回归次数的经验公式提出了修正意见。本研究的成果对于高层建筑抗震设计有一定的参考价值。

| Abstract: | This paper discusses the characteristics and adaptabilities of ARM solutions of power spectrum recorded from several famous earthquakes through numerical analysis and compares with solutions of fast Fourier transform (FFT)method.The results of the comparison show that for diffrent records of earthquakes the ARM solutions of power spectra are equivalent to the solutions of FFT method graduated by a certain spectral bandwidth. This study puts forward some amendments for the recommended empirical formula of autocorrelation regression number of times and the results of the study have reference values for aseismatic design of high-rise buildings. |
