Short-Period Terms in Time and Latitude Observations Made with the Herstmonceux Photographic Zenith extend over a longer period and have been re-reduced using improved catalogue positions. Analytic smoothing of these data has furnished observational residuals that reveal very clearly the effects of short period terms with relatively small amplitudes.作者: 強制性 時間: 2025-3-22 22:37 作者: 枯萎將要 時間: 2025-3-23 01:51
Some Difficulties in the Theory of NutationFedorov (1958) made a splendid discussion of data on the nutations; Vicente and I made a theory, taking account of a fluid core and of an elastic shell. The agreement was far better than had been found before, but some inconsistencies remained.作者: 沒有準備 時間: 2025-3-23 08:50
On the Effect of the Scale Value on the Principal Nutation Terms Derived from the ILS DataThe scale values used in the work of the International Latitude Service are known to be in some cases evidently erroneous. After trying various methods to improve these values, E. P. Fedorov (1963) decided on the one based on the computation of the mean latitudes obtained from observations of the pairs with zenith distances of opposite sign.作者: trigger 時間: 2025-3-23 10:36
Nutation Terms Derived from the Z- and the τ-Term of the IPMS SystemThe non-polar common terms, z and τ, of the IPMS system are analyzed for determining amplitudes of some terms of the forced nutation. The method of analysis and the results obtained are described briefly. Comparison is made with theoretical and other observational results. A fuller account of this work will be published elsewhere.作者: 誘惑 時間: 2025-3-23 16:14 作者: Fresco 時間: 2025-3-23 21:06

A Determination of the Principal Term of NutationThe method for deriving the amplitudes of the principal term of nutation from the z-term of latitude and the corresponding term of UT (here denoted by w) is well known (Yokoyama, 1977).作者: Intractable 時間: 2025-3-24 10:46 作者: 高調(diào) 時間: 2025-3-24 16:41 作者: Flinch 時間: 2025-3-24 19:10
Reduction of the Past ILS Data in a Uniform Systemon the constitution of the Earth’s interior. Indeed, the results of analyses of the nutations agree well with those predicted by theory for a fluid core. This shows that the matter of the outer core, 3,000 km and more below the Earth’s surface, is not only in a fused state but also is a “fluid” whic作者: Landlocked 時間: 2025-3-24 23:21

This may be due to an error in the classical terms of nutation or to the neglected nutation in space produced by the theoretically predicted nearly-diurnal wobble (Hough, 1895; Poincaré, 1910; Jeffreys, 作者: 吝嗇性 時間: 2025-3-26 05:59 作者: Observe 時間: 2025-3-26 09:27 作者: impale 時間: 2025-3-26 12:37
