Firstly, we use the mixed coordinates. More precisely, we use the spherical coordinates for independent variables in space, and so avoid the approximation of boundary conditions on the surface, which is required, if we use the Descartes coordinates.

我们所设计的求解Navier-Stokes方程的混合谱格式具有如下的一些特点：首先，我们采用混合坐标方法，即用球面坐标表示空间自变量，而用Descartes坐标表示速度分量。

More precisely, we use the spherical coordinates for independent variables in space, and so avoid the approximation of boundary conditions on the surface, which is required, if we use the Descartes coordinates. Next, we use the Descartes coordinates for the components of velocity, which simplifies the actual computation and numerical analysis essentially.

Heat flux increases remarkably in spring, so layering comes into being gradually and concentrates on the central BS where tidal mixing is weak; whether the range or intensity culminates during the Summer Solstice; stratification is weakened in accompany with the decrease of heat flux in the fall, and is still apparent in BS strait; the gale enhances vertical stirring of sea water, so no obvious stratification exists in winter.

春天海表热通量显著增强，层化结构也开始形成，主要分布在潮汐混合较弱的中央水域；夏至时节层化结构无论是发生范围还是层化强度都达到极致；进入秋季，层化强度伴随着海表热通量的减少而削弱，分布区域也逐步向渤海海峡转移；冬季大风进一步增强了海水的垂向混合，此时渤海不再有垂向分层。

An on-line blind source separation algorithm of non-stationary mixed signals is presented. The algorithm uses the multiple time-delayed decorrelation and natural gradient rule to obtain the stationary point of the cost function, only a small number of observed samples is needed to minimize the Frobenius norm of the correlation matrices, so the computing cost is low and continuous separation calculation could be realized by on-line operation.
