通过对帆式张网模型水池试验，研究了帆式张网网中部分网衣结构对网具性能的影响。试验表明，（1）背腹网网口网衣弧形剪裁后，背腹网网衣受力均匀程度明显改善，网具阻力平均下降3．9％，网口垂直扩张平均增加4．7％，水平扩张平均增加7.2％。（2）背腹、侧网网口网衣剪成弧形后，网具阻力平均下降24．2％，水平扩张低速时有所下降，但高速时开始增加，平均增幅为3．5％。侧网网口网衣弧形剪裁对网日垂直扩张影响不大。
Through the test of the sail net model pool, the influence of some net structure on the net performance of the sail net was studied. The results showed that: (1) After the dorsal net mesh mouthwork was arc cut, the evenness of the dorsal belly mesh clothing was improved obviously, the resistance of the net tools decreased by 3.9% on average, and the average vertical expansion of the net mouth increased by 4.7% , The average expansion of 7.2% increase. (2) dorsal, side net mouth Net clothing cut into an arc, net resistance decreased by 24.2% on average, when the level of expansion slowed down at low speed, but began to increase at high speed, the average increase of 3.5%. Side net mouth net clothing arc cut on the network vertical expansion has little effect.
