在模型试验水槽中,进行了拖网模型网囊速度场的研究,模型网与实物网的比例为1:5。为了使网囊预先展开,把模型网囊结扎在骨架上。模型网囊用绳索系在测定计的杆上,以便
In the model experiment tank, the research on the velocity field of the trawl model mesh was carried out. The ratio of the model net to the physical net was 1: 5. In order to pre-expand the mesh, the model mesh ligation in the skeleton. The model mesh was tied to the rod of the gauge with a rope so that
