Abstract:
Two-dimensional non-linear hydrodynamical equations are solved by using perturbation method and treating slopping beaches as bottom boundary conditions so that a kind of solution for nonlinear progressing waves is obtained.The first order of approxim...

Abstract:
A solution is obtained via Green's function for steady wind-driven flows on shallow continental shelf with linearly bottom slope.Friction is parameterized in terms of constant horizontal and vertical eddy viscosities, with flow patten illustrated.

Abstract:
The current elements of the Kuroshio in the East China Sea are analysed and discussed using the temperature-salinity and GEK data of the PN section obtained during 1972-1983.The calculations have proved (ⅰ) that the 12-year's mean volume transport of...

Abstract:
Based on linear theory of sea waves, the height distribution of the intersections of wave surface with its envelope is derived.The distribution may be regarded as that of the significant crest heights under certain conditions.Some properties of this ...

Abstract:
Since the mode filtering is a certain sort of "space filtering", the matter of the utmost concerns the "side lobe" produced by some simplified processing in practice instead of the ideal orthogonal operation.In this paper, the following problems are ...

Abstract:
A new and simple method for separation and determination of U and Th in manganese nodules has been developed.The results show that the addition of NH4NO3 to the dilute HNO3 medium increases the selectivity of anion-exchange separation of U and Th.The...
