【摘要】 本文对1984年BIH年报刊出的1962.0—1982.0年ERP序列中的日长变化LOD序列,用自回归谱分析的Marple算法进行了短周期波动的检测,得到了和潮汐短周期波M_f、M_m和MS_m的频率很吻合的三个明显的谱峰.还用LOD序列进行了这三个分潮波的振幅的估计,并计算了在周月波频率和半月波频率上的地球弹性形变参数K/C:（K/C）_Mm=0.91±0.16,（K/C）_Mf=0.93±0.16,和K/C的理论值略有差异.更多还原

【Abstract】 In this paper, we analyse short period fluctuation of tides with Marple estimate for new LOD series of ERP （1962.0—1982.0） reduced by Dr. Li Zhengxin. Marple spectral analysis reveals sharp peaks at 13.652, 27.586 and 31.746 days. They are consistent with tidal terms M_f, M_m and MS_m. Their amplitudes are estimated. K/C are calculated at fortnightly and monthly frequencies. A least squares solution gives （K/C）_Mf=0.56±0.21, （K/C）_Mm=0.89±0.21. The response to frequency of the elasticity of the earth can not be concluded from the difference of these values.更多还原
