| 1. | Alongshore bars are produced at the point of wave break . 沿滨砂洲是在波浪拍岸处形成的。 |
| 2. | Some of the bars and troughs are exposed by low tide . 一些砂洲和沟槽在低潮位时,露出于水面。 |
| 3. | The further growth of a bar is due to a lowering of sea level . 砂洲的进一步生长是由于海平面正在下降的结果。 |
| 4. | Tidal channels, deltas, and washover fans are characteristically associated with offshore bars . 潮汐水道、三角洲和冲刷扇典型地与滨外砂洲伴生在一起。 |
| 5. | The deepest relief along the bar is on the shoreward side where it is backed up by a lagoonal channel . 砂洲上最陡峻的地形位于泻湖水道积滞处的向滨一侧。 |
| 6. | Severe storms and hurricanes are capable of completely destroying many well-developed submerging bars . 强烈的暴风雨和飓风具有彻底摧毁许多发育良好的水下砂洲的能力。 |
| 7. | The sand carried outside the bar is spread out over the slope by the expanding head of the rip current . 从砂洲外面搬出去的砂质物,在急流的汹涌水头作用下被展布于整个斜坡上。 |
| 8. | The growth of these bars is limited by the depth at which waves will plunge and prevent further sand encroachment . 这些砂洲的生长仅限于波浪能冲进的深度,并且阻挡了外边砂质物的进入。 |
| 9. | Such thickening is due to the relative noncompactibility of the sandstone of the bar as compared with the enclosing shale . 这种增厚是由于砂洲砂岩与其周围的页岩具有不同的不可压实性造成的。 |
| 10. | The sea floor of this continental shelf usually undulates gently, rising occasionally to the surface in offshore banks or island . 这个大陆架海底通常缓慢起伏,偶尔以岸外的砂洲和岛屿的形式露出水面。 |
