| 3. | First . upon the former research work and field measurements in the radial sandbanks area , the characteristics of geomorphology , hydromechanics and the relationship between them are preliminarily analysed
本文首先针对辐射状沙脊群现有的文献及实测资料，初步分析研究了南黄海辐射沙脊群海域地貌和动力特征，以及动力与地貌的关系。 |
| 4. | 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。 |
| 5. | 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。 |
| 6. | Because during the sedimentation of the flood plain - estuary fades , the conditions of sea level rising , tidal regime , sediment supply and accommodation space were suitable for the development of a tidal ridge system , the sand lenses associated with this facies may represent tidal ridge formation in the incised valley
在河漫滩河口湾相沉积期问，由于海平面上升、潮流体系、沉积物供给和可容空间条件适合一个潮流沙脊体系的发育，其中的砂质透镜体可能代表了下切河谷内发育的潮流沙脊。 |
| 7. | The tidal current in the radial sandbanks area apparently has directional to - and - fro movement , which can be observed not only from tidal ellipses , but also from water particle traces . the calculated distribution of tidal velocity in this area shows that the average velocity is around 0 . 6 to 1 . 0 m / s
平面潮流椭圆、水质点迹线、潮流流速特征研究表明，辐射状沙脊群海域潮流具有明显的定向往复流形式，平均潮流流速一般为0 . 6 1 . 0m s ，满足形成潮流沙脊的水动力条件。 |
| 8. | It has been proven that , from the propagation process of the tidal waves and wave energy rates , the whole radial sandbanks area is controlled by the progressive tidal wave in the south and the rotational standing tidal wave in the north . these two waves merge at qianggang and induce a large tidal range
通过对潮波波面传播过程及潮波能流率研究表明，辐射沙脊群海域为南部太平洋前进潮波和北部旋转潮波所控制，两潮波系统在?港外海辐聚辐散，形成大潮差区的特点。 |
| 9. | Through studing the plane and vertical hydromechanical characteristics in the radial sandbanks area , the mechanisms of the formation , maintenance and asymmetrical distribution of the radial sandbanks are understood . it ' s well known that the directional to - and - fro movement and strong tidal current are the necessary dynamic conditions for the formation of tidal current sandbanks
通过对辐射沙脊群海域平面及立面动力特征的研究，基本探明了南黄海辐射沙脊群形成发育和维持的水动力机制，以及其不对称分布格局与动力因素的内在联系。 |
| 10. | It has been proven that the differences of magnitude and distribution of tidal currents , wave energy rate , suspended sediment concentration and the stokes number result in a asymmetrical distribution of sandbanks between the north and south . the sandbank surface area and length in the north are lager than those in the south , but its cross section area is less than that in the north
各种动力特征平面分布规律研究表明，辐射沙脊群南北沙脊不对称分布的格局是潮流沙脊对潮流往复流性质的强弱分布、潮波能流率大小分布、含沙量的平面分布规律及斯托克斯数的大小分布的动力响应。 |
