摘要
根据中国沿海现有五十多种具有先进性、代表性的底层有翼单囊拖网网具资料，统计出大量的网具设计参数。除了介绍九种拖网网衣设计参数的符号及其意义外，还分别论述了中国沿海四种底层拖网网型的网衣设计参数，并对其不同的设计参数之间作了分析比较。
Based on the data of more than fifty typical advanced bottom trawls with single bagand wings currenty used in the coasts of China, the author computed a series of design parameters from many types of different fishing nets. Apart from the introduction of signs, calculatingmethods and the significance of the parameters of 9 trawls,this paper also compared and analysedthe design parameters of four netting types of bottom trawls being used in the coasts of China.
