摘　　要：通过3个航次矩形V型曲面网板与V型网板作业性能和生产效果的对比试验。结果表明:在相同作业条件下,矩形V型曲面网板的水平扩张力可增大43.75%,阻力下降1.3%;试验船总产量和总产值分别比对比船提高18.13%和17.4%,试验船每消耗1 t柴油所获得的产量、产值与利润均可高于对比船。Rectangular Ⅴ-type curved otter board and Ⅴ-type curved otter board were tested to compare the operation characteristics and production effect during the three trips. The horizontal spread of the rectangular Ⅴ-type curved otter board increased by 43.75% and its resistance reduced by 1.3%. The total catch and total value of the experimental fishing vessel increased by 18. 13% and 17.4%, respectively, under the same operatinal conditions. Meanwhile, the catch, value and profit per ton fuel consumption by the experimental fishing vessel were higher than those of the control. It has achieved better social - economic benefits and good effect of economizing on energy.
