【摘要】 利用１／７比例的网具模型，在拖曳水槽中对六片式拖网进行水槽试验。得出网口高度公式为：Ｈ—０．１２１ＣＶ－０．８１１。网具阻力公式为：同时得出力纲上装配浮子能提高网口高度３．６％．上中纲与上纲长度之比不能大于０．１４０，上边纲长度可大于相对应的力纲３．３％等设计网具数据。更多还原

【Abstract】 A series of experiments for model test of six panel trawlnet with the 1/7scale were done in towing tank. The results can be summarized as follows:1. The formula of headline height of these nets is2. The formula of drag of these nets isFurthermore, bellyline with floats can raise 3. 6% of headline height. The ratio of the lengthof headline rigging with square netting to hesdline can not be over 0. 140. The length of theheadline rigging with wing netting can be longer than that of the bellyline 3. 3%.更多还原
