弹性潮和滞弹性潮的小滞后和大滞后。两种流变物理理论的虚同一性
The small and large lags of the elastic and anelastic tides. The virtual identity of two rheophysical theories
摘要：
这封信的目的是讨论两个最近的潮汐理论的虚拟身份：费拉兹-梅洛（Cel.机械动力学116，109，2013）和由Correia等人开发的Maxwell模型（Astron. Astrophys. 571，A50，2014）。它包括讨论的基本方程的理论，其中，在这两种情况下，包括一个弹性和一个滞弹性组件，并表明，这两个理论的基本方程是等价的，不同的只有一个数值因子的滞弹性潮汐。它还包括滞后的讨论：滞后的全潮（大地），占主导地位的弹性组件，和滞弹性潮汐的阶段。在旋转的岩石体中，没有被困在自旋轨道共振中（例如，地球）的大地滞后接近于零，并且滞弹性潮汐中的半日辐角的相位接近于90度。结合来自卫星跟踪数据和来自Topex/Poseidon卫星高度计数据的潮汐解所获得的结果，扩展到确定在地球的滞弹性潮汐的半日幅角的相位为σ_0 =89.80 \pm 0.05度。
英文摘要：
The aim of this letter is to discuss the virtual identity of two recent tidal theories: the creep tide theory of Ferraz-Mello (Cel. Mech. Dyn. Astron. 116, 109, 2013) and the Maxwell model developed by Correia et al. (Astron. Astrophys. 571, A50, 2014). It includes the discussion of the basic equations of the theories, which, in both cases, include an elastic and an anelastic component, and shows that the basic equations of the two theories are equivalent and differ by only a numerical factor in the anelastic tide. It also includes a discussion of the lags: the lag of the full tide (geodetic), dominated by the elastic component, and the phase of the anelastic tide. In rotating rocky bodies not trapped in a spin-orbit resonance (e.g., the Earth) the geodetic lag is close to zero and the phase of the semi-diurnal argument in the anelastic tide is close to 90 degrees. The results obtained from combining tidal solutions from satellite tracking data and from Topex/Poseidon satellite altimeter data, by Ray et al., are extended to determine the phase of the semi-diurnal argument in the Earth's anelastic tide as sigma_0=89.80 \pm 0.05 degrees.
