拖网曳纲力学计算的研究

曳纲是拖网渔具中的重要组成部分，对曳纲进行力学计算，不但对于研究拖网渔具，而且对于拖网作业水层都是十分必要的。本文阐述了拖网船匀速直线运动时曳纲作为平面问题和空间问题以及加速运动时的情况，并将计算结果进行比较和分析。

RESEARCH ON MECHANICAL CALCULATION OF TRAWL WARP

As the warp is a major part of the trawling gear,it is fully necessaryto make a mechanical calculation of the warp for the research on the trawlinggear and the water depth of trawling .In this paper ,the two-dimensional andthree-dimensional patterns of the warp in the water are specifically describedwhen the trawler is moving with uniform or variable velocity,and furthermore,the calculated results are carefully compared and analysed.
