【摘要】 半个多世纪以来渔具模型试验已成为设计和制作渔具的重要方法。多年来各国学者先后提出了多种模型试验的准则,其中有日本的田内、英国的W狄克逊、前苏联的AΛ弗里特曼、美国的BA克里斯登生等。本文从力学相似的基本原理出发,对渔具模型和实物之间的速度比、特征长度、力比等三方面进行了分析,对各个准则作了比较,并对今后渔具模型试验提出了看法。更多还原

【Abstract】 The fishing gear madeling has become a primary method of designing and manufacturing fishing gears for more than half a century.For many years the scholars from various countries have put forward several criterions in fishing gear modeling as M Tauti(Japan),W Dickson(England),A A Ferro(S U),B A Christensen(U S A)etc.On basis of the basic principle of mechanics similarity,the analysis and comparison was carried out in the velocity scale,characteristic length and force scale between model and full-scale measurement as well as among several criterions. Finally,Some suggests and ideas were put forward in hydrodynamic modeling in the future.更多还原
