地球自转ERA-2005数值理论评述
Comments on the ERA-2005 numerical theory of Earth rotation
摘要:
最近发表在《天体力学》上的两篇论文(Krasinsky 2006,Krasinsky和Vasilyev 2006)提出了一个地球自转变化模型,称为ERA-2005,该模型基于一组新的变形地球自转方程的数值积分,然后将积分结果与VLBI数据拟合。这些论文声称,该模型优于任何其他现有的模型。本说明的目的是揭示新理论基本方程推导过程中的基本错误,以及数据拟合过程中的严重缺陷;这些错误使得ERA-2005不适合作为章动和岁差的天文学模型。
英文摘要:
Two papers recently published in Celestial Mechanics (Krasinsky 2006, and Krasinsky and Vasilyev 2006) have presented a model for Earth-rotation variations, called ERA-2005, based on numerical integration of a new set of equations for the rotation of a deformable Earth followed by a fit of the results of the integration to VLBI data. These papers claimed that this model was superior to any other existing model. The purpose of this Note is to bring to light fundamental errors in the derivation of the basic equations of the new theory, compounded by serious deficiencies in the process of fitting to the data; they make ERA-2005 unsuitable for consideration as a geophysics-based model of nutation and precession.
