摘要
利用了主成分分析方法,分析了中国地壳运动观测网络主要基准站垂直位移时间序列的频谱特征,得出了站点的垂直位移变化具有很强的周年变化特征。
Using principal component analysis method, the spectrum characteristics in GPS vertical displacement time series of main fiducial stations in the crustal movement observation network of China is analyzed. The result indicates that the time series show strong annual characteristic.
