与foretop相关的网络例句 [注：此内容来源于网络，仅供参考]

Knowing the height of your own mast to the foretop position you can estimate the range to the target by trigonometry using the angle the sight has to be depressed to align with the waterline of the target

由於桅楼的高度是已知，利用简单的三角测量便能大致估算敌舰的距离。

While at Gotenhafen, the two 10.5 meter stereoscopic base rangefinders are installed above the foretop and after command posts.

当到达哥腾哈芬，在得到命令后两坐10.5米实体测距装置安装在了舰体前端的顶部。

According to McGiffin, range was estimated from an observer from the foretop by a simple depression range-finding sight which measures the angle from the horizontal to the waterline of the enemy ship.

依照麦吉芬所言，当时测量距离的方法是仰赖一名站在全舰最高处的人员进行简单的俯瞰式测量──测量水平线到敌舰水线之间的夹角。

Range estimates from the foretop would not have been very useful at that time, especially given the decimated gun crews and difficulties relaying data.

这种时候桅杆顶的测距作业并不十分管用，尤其是当炮手伤亡惨重以及难以传递更新的射击资料之际（此时桅楼测量员与炮位之间可能得靠旗号沟通）（编者注：因为全舰通话道此时已经被击破失效
