摘要
就２２０～４４１ｋｗ的中小型渔船动力装置选型的历史沿革，从船、机、桨匹配理论分析，结合中国南部海区渔民实践造就已使用的情况，论述大家所关心的几个问题。认为：不能只用“单机单桨”一种推进型式；双机双桨能发挥主机功率，合理安排动力装置，安全性及其经济性均有优越之处，适合我国南海大多数渔区渔港实际情况。
Surveying deve lopment of power-device type from 220～441kw. used fish ship and giving a theoreticd treatment of vessel engine and propeller natching, the paper deal with some interested problems. Accordirg to condition of the South Sea ports of china,author asserts thst adopting double engines and propellers can increase main-engine usge and show advantages over single engine and propeller such as safety and economy.
