本文依次用悬链线和抛物线理论分析推导了金枪鱼延绳钓具的两种投放方法以及在渔场各水层相同流态下钓具充分沉降后所有钓钩位置包括深度和相互间水平间距的计算公式 ,可用于作业参考。
In this paper, two kinds of delivery methods of tuna longline fishing tackle were deduced by catenary and parabola theory in turn, and the formulas for calculating the depth and horizontal spacing of all the fishing tackle positions after the fishing tackle was fully settled in the same flow regime of each aquifer were available. For job reference.
