摘要
本文对“关于平稳过程谱密度运算中的两个问题”一文中涉及的问题,提出了更为简捷的推导方法,并导出前文一系列公式。订正了前文功率谱的定义。论证了获得路面谱的途径。
This paper is based on the paper On two Problems in Calculating Autospectral Density of Stationary Process. It preseots a new more simple and convenient deducting method. A series of important formulae are deduced in detail. And correction is made to the definition of power spectrum in the first paper. The simple and convenient measuring method of road pavement spectrum is proved.
