摘要
介绍了列率谱分析的两种谱估计方法 ;并矢周期图法和并矢相关法。通过实测资料比较表明 ,两种谱估计方法的计算结果基本一致。文中利用不同环境条件下的实验室资料对列率谱进行了分析 ,并与频谱的部分计算结果进行了比较 ,对其存在的差异给出了可能的物理解释。
Two estimation m ethods of sequence spectral analysis are systematically introduced in this paper . The estimated sequency spectra with l aboratory records show that the two diff erent methods lead to nearly the same re s ults. Moreover, the calculated frequency spectra are compared with the sequence spectra for different observation data, and the physical insight into the differ ence between the sequence spectrum and t he frequency spectrum is discussed so as to propose a probable physical explanat ion.
