本文提出并讨论了一个包含海洋热质交换和外力功的熵平衡方程。结果表明，由热传递引起的熵通量约为-555.6mWm-2K-1，与风应力功有关的熵通量较小，约为-0.09mWm-2K-1，由质量传递引起的熵通量为-0.02mWm-2K-1，所有熵通量之和为-555.7mWm-2K-1，当海洋处于稳定的气候条件下时，海洋内部熵的平均产生率必须为555.7 mWm−2K−1。
An entropy balance equation including the transfers of heat and mass, work of external force of the ocean is presented and discussed. Entropy flux through the sea surface are calculated, and the results show that entropy flux due to heat transfer is about −555.6 mWm−2K−1, entropy flux connected with the work of wind stress is relatively smaller at about −0.09 mWm−2K−1, entropy flux due to mass transfer is −0.02 mWm−2K−1, the sum of all the entropy flux is −555.7 mWm−2K−1, the mean rate of generation of entropy inside the ocean must be 555.7 mWm−2K−1 when the ocean is in a climatic steady condition.
