摘要
本文将JYD地极坐标系统的长期分量x0、y0与BIH、CSR系统的x0、y0作了比较,并对前者的相对长期稳定度进行了分析。在此基础上对JYD、BIH两种地极坐标之间的系统差进行了研究。
From a comparison of the long term components Xo and Yo among the three polar coordinate systems: JYD, BIH and CSR, an analysis of the long term stability of the JYD system is made; The long terms of the systematic difference between the JYD and BIH systems is also given.
