为使刺网网目受力均匀,改善网目变形和减小目脚张力,作者用理论分析和实验方法说明中层流网处于均流状态的水中与水流没有相对位移;设计制作实验装置,用静力学模拟法试探刺网网衣上受力分布的规律,得出了浮、沉子档间距与网高之间的关系式;进而提出了合理分布浮沉子的三项原则及减小目脚张力的措施。
In order to make the gill nets mesh evenly and improve the deformation of mesh and reduce the tension of the mesh feet, the author uses theoretical analysis and experimental methods to show that there is no relative displacement between the middle layer flow net and the current in the same flow state. The experimental apparatus Static mechanics method to test the law of force distribution of gingival net clothing, get the relationship between floating and sinking gear pitch and height of mesh; then put forward three principles of reasonable distribution of floating sinker and reduce the size of feet Tension measures.
