Optimized in its structure , and can be used to rough polishing , finshing polishing and 11nall m polishing of all kinds of gyroidal - shape metal ware 2mb414c拋光機是2mb4140系列拋光機第三代產品,它為2mb4140a拋光機的更新換代產品,繼續保留2mb4140a的性能特點,但結構更優化,用于各種回轉體形狀金屬器皿的粗精拋光和精細拋光。
Thirdly , the basic configuration plan of a ship undocking assisted by different number of tugs is given . the relationships among the gyroidal moment , gyroidal time and drag forces of tugs in the process of ship undocking are analyzed . the margin of the tugs " towing forces during the ship undocking and turning process is studied 三、制定了不同數量拖輪協助船舶出塢時的基本布置形式,給出了不同拖輪協助船舶出塢時的拖輪布置示意圖,并試驗分析了船舶出塢回轉力矩與回轉時間和拖輪拖力之間關系,并確定了用于船舶出塢回轉的拖輪拖力的余度大小。
