| 摘 要： | 提出了“网衣理论总强度”、“网衣相对强度”两个概念。解决了底拖网设计中根据母型例或设计参考网初步确定设计网网口网线粗度的问题。并根据“网衣理论总强度”和“网衣相对强度”概念统计出我国沿海各种渔船主机功率的底拖网各部位网衣理论总强度和网衣相对强度数字范围,为我国底拖网设计网目长度与网线粗度之间关系的处理提供了理论依据。

| Abstract: | Referring to the result made in reference 3), a concept "Total tenacity of the netting theory" is proposed in this paper. Using this concept, the relationship between the round length and the fineness of netting twine in net gape can be easily dealt with. Another concept "Relative tenacity of netting" is also proposed according to the supposition that two nettings with same width ought to have same theoretic total strength. This concept can be used to solve the problem of determining the fineness of netting twine in net gape of the designed bottom trawl according to mother-type net or reference net. To bottom trawl used in sea fishing boats with defferent main engine power in our country, statistics of theoreric total tenacity and relative tenacit of nettings in each part have been given in the paper, which provide the theoretical basis for determining the fineness of netting twine in the design of bottom trawl. |
