        This paper deals with the theory for rotational motion of a two-layer Earth model (an inelastic mantle and liquid core) including the dissipation in the mantle-core boundary(CMB) along with tidal effects produced by Moon and Sun. An analytical solution being derived using Hori's perturbation technique at a second order Hamiltonian. Numerical nutation series will be deduced from the theory.

        A model experiment of purse seine by the circulating water tank was carried out on the changes of net shape and the tension of purseline under operation in two layer current. In the circular tank, the two layer current was made by cutting off the current of upper layer and producing the bottom current by the equipment shown in Fig. 1. The model experiment of purse sein was made on a reduced scale 1 :400, and the experiment was carried out according to the Tauti's model law. When the bottom current of O. 5 knot flows to lower part of three-eighths of net, following results are derived. The depth of sinkerline reached only about 80% of that of no current set. The horizontal shift of sinker line caused by the bottom current is maximized in tight set. The enclosed area by the floatIine immediately after the completion of set net is 61. 5% in tight set, 50. 0 % in loose set and 54. 1 % in lateral set of those in the case of no current. In the first half period of pursing, the tension of the purseline is enhenced by the bottom current and the pattern of increasing is irregular in the tension curves.

        The circulation of the Yellow Sea and the East China Sea is simulated by means of the two layer numerical model with bottom topography: The circulation inside the Yellow Sea is mostly affected by the Kuroshio Current in the case without the wind stress exerting on the surface. The main current is trapped along the continental slope by the characteristics of geostrophy. The second strong current region is appeared from the southern coast of the Ghina to the Korea Straits, which is characterized the western boundary current. The circulation inside the Yellow Sea is rotated in clockwise direction even though its magnitude is negligibly small compare with the other current, for example, the tidal residual current.
