本文用最大相关时间的概念研究佘山台和仑坪台地磁场日变形态的位相关系。处理了1974年垂直分量和磁偏角的资料。用MEM分析了最大相关时间变化的功率谱,结果明显地揭示出它含有周期为14.6天的变化。对此现象,本文提出一种可能的解释,即部分海洋月相潮汐电流沿东海经台湾海峡(导电通道)时,在海峡两边产生的磁场变化存在差异,因而形成最大相关时间的半月周期变化。
In this paper, the concept of maximum correlation time is used to study the phase relationship between the daily magnetic field and the Seshan platform and the Lunping platform. The 1974 vertical component and declination data were processed. The power spectrum with the largest correlation time change was analyzed with MEM, revealing clearly that it contained a change of 14.6 days in duration. A possible explanation for this phenomenon is presented in this paper. When some tidal currents of the moon’s oceans move along the Taiwan Strait (conductive channel) along the East China Sea, there are differences in the magnetic fields generated on both sides of the Strait, resulting in a half-moon periodicity of the maximum correlation time.
