One of the key issues in the marine ecosystem dynamics studies is to accurately estimate the dissolved biogenic substance flux across the sediment-seawater interface in the shelf sea.

陆架浅海沉积物—海水界面上的溶解态生源物质通量的准确估算是海洋生态系统动力学研究中的关键性问题之一。

When these characteristics are considered and assume that the interface of sea water and sediment is a plane, the expression of reflection coefficient is derived.

考虑到这些特征，再假设海水与沉积物的界面是平的，导出了平面声波在其上的反射系数的表达式。
