摘要
从海水质量守恒律、盐量守恒律、动量守恒律、熵变化律和海水状态律出发,给出了低频变密度海洋运动的原始控制方程和它的各类实用形式。在推导的过程中着重明确控制方程各种近似形式的数学物理意义,这使我们在使用这些方程时更严格、更准确。
In this paper, the primitive equations for the low-frequency variable density motion in the ocean and their practical forms are given from the seawater law of mass conservation, law of salt conservation, law of momentum conservation, equation of entropy evolution and equation of state, and the emphasis is placed on the mathematic and physical implications of various approximation forms of the governing equations in their derivation process, which will enable us to strictly and accurately use these equations.
