基于空间大地测量数据建立板块运动的欧拉矢量具有更优的现势性。本文对其计算的3种几何模型进行了理论分析,并且利用IERS发布的ITRF2000速度场数据对上述3种几何模型进行了比较。结果表明,3种几何模型得到的板块运动的欧拉矢量具有统计一致性。但是,由它们得到的板块运动的欧拉矢量最大差异约1 mm/a,整体旋转量最大差异约0.2 mm/a,这对于高精度的大地测量和地球动力学应用影响显著。朱文耀等采用的几何模型更加合理,拟合精度更高,因而建议利用该模型进行板块运动欧拉矢量的拟合。 The Euler vector based on the geodetic data of the geodetic space has better potential. In this paper, the three geometrical models calculated are analyzed theoretically, and the three geometrical models mentioned above are compared with the ITRF2000 velocity field data released by IERS. The results show that Euler vectors of plate motion obtained by the three geometric models are statistically consistent. However, the maximum Eulerian vector difference of plate motion obtained by them is about 1 mm / a, and the maximum difference of total rotation is about 0.2 mm / a, which has a significant impact on high-precision geodesy and geodynamics applications. Zhu Wenyao and other geometric models used more reasonable and higher accuracy, it is proposed to use the model plate Euler vector fit.
