摘　　要：针对目前小型渔船单拖网使用的铁木结构矩形网板十分笨重的缺点，设计了帆布柔性网板。用2．94kw渔船进行海上对比试验，结果：帆布网板自重小，阻力小．收绞轻便，劳动强度低，产量与木质网板基本持平。计算分析认为，网板平面与海底的夹角以80-85°较为适宜。In view of the shortcomings of the cumbersome rectangle board made of iron and wood, now used on the small sized single boat trawl, a canvas board was designed. The result of a contrastive experiment conducted on the fishing boat with 2. 94 kW in the sea showed that the canvas board has such merits as light weight, small resistance, easy to twist the trawl and low labor intensity, and its catch as much as the trawl with the wood board. Calculation analysis proved that the angle between the plane of the canvas board and the sea bottom is comparably good for 80～85°.
