脊顶 meaning in Chinese

crestal culmination
ridge course

The distributions of the residual flow and the residual discharge from the numerical model show that the residual circulation flows around the sandbanks contribute significantly to the deposition at the peak of sandbank , and closely related to the sandbank development
另外还研究了辐射沙脊群海域的余流及余流量的分布，发现在潮流沙脊两侧存在平面余环流，余环流将有利于泥沙在脊顶沉积，与潮流沙脊的维持发育密切相关。
The existence of the asymmetrical residual transverse circulation flows in pair is discovered in the residual vorticity field along the passage and sandbank cross section . the transverse residual circulation flow is favorable to sediment ' s moving to the peak of sandbank and the development and maintenance of sandbank
首次发现，在潮涨潮落过程中，深槽中及沙脊两侧均存在一组方向相反、不对称余涡度场(余环流场) ，横向余环流的存在将有利于沙脊两侧的泥沙均向沙脊顶运动和堆积，是潮流沙脊的形成和维持重要动力因素。
