| 摘要: |
| 通过大量的海上网箱沉浮试验和分析，阐述了国产HDPE升降式网箱在自然海洋环境状态中，受风、浪和流等客观因素的作用与影响，使其在下沉过程中各浮管舱间下沉速度不一致，导致升降式网箱最终不能完全沉入水下，形成外在成因；而浮管舱内进水水体的流动则是造成网箱重心偏移和整体倾斜的内在因素，控制网箱下沉倾角，清除排气管路进水阻塞是升降网箱下沉的关键技术。 |

| Study on key techniques for submergence of HDPE submersible deep-sea cage |

| Abstract: |
| The interaction between HDPE submersible deep-sea cage and wave current was analyzed by a number of in situ tests for cage submergence. The submersible cage could not sink completely because the sinking speed of the pipe cabins was different. And another important reason was the cage barycenter drift due to the water flow in the pipe cabins.The key technology of net cage sinking is controlling the sinking obliquity and eliminating block of the exhaust pipeline. |
