bowline(名词)
/ˈboʊlaɪn/
Tie a bowline at the end of the rope. 在绳子末端打一个单套结。
Because the bowline forms a secure loop that’s easy to untie after loading, sailors often use it when fastening a line to a post in rough weather. 因为单套结能形成牢固的绳圈,而且受力后也比较容易解开,水手在风浪大时常用它把缆绳系在桩上。
bowline 源自航海用语,最初与“帆的前缘(迎风边)”有关:bow(船首/前部)+ line(绳索)。早期“bowline”可指牵引帆角或帆缘的绳索;后来该词也常用来指一种常见且用途广的“固定绳圈”绳结(单套结)。
