As a natural result, the mass matrix is a positive definite consistent and time-independent one, and the two time-dependent and nonsymmetric matrice, that is, the "gyroscopic damping" and "centrifugal stiffness" ones, don't exist in the equation.

在不附加任何&运动学&假设的情况下，作为自然的结果，方程的质量阵是正定、协调的常数阵；方程中不存在两类时变的非对称系数项，即所谓的&陀螺阻尼&项和&离心动刚度&项。

In this paper, the rotary spectra of sea current and residual current are calculated for the data of cunent vector time series acquired through a mooring buoy located at (114°20.5'E, 20°04.8'N). Subsequently, the preliminary analysis for the internal structures of current in this area is done from these results of calculation and a lesidual current with a three days period is found in this sea area.
