| 摘 要： | 本文用计算确定双拖网曳纲的空间形状与张力,估算在一定拖速下两船间距、水深与网具水平扩张的关系。根据模型试验测出的水平与垂直扩张值,换算出双拖网网口高度并与实测结果比较。可针对各级渔轮和生产条件,广泛计算并列出图表,以便在生产中用于双拖网调整。

| Abstract: | In this paper the theoretical calculating method for warp shape and tension is used to detemine the relations between fishing boar distance, water depth and trawl horizontal opening under a certain towing speed Then, the trawl headline height is converted according to the model testing values of horizontal and vertical openings and compared with the measured data at sea.The estimating values are in good agreement with measurements. Using the estimating method described in this paper, various diagrams and curves can be gained for different trawlers and fishing conditions and may be used in commercial ptacticc. |
