When the village gathered by the construction site, Mortenson met them, plumb line, level, and ledger in hand.

当村民们聚集在建附近时，摩顿森拿着铅垂线、水准仪分类与他们会面。

铅垂线也用于测量竖井的深定隧道的坡。

" You're making everyone crazy." " Then he reached out and took my plumb line, and my level and my account book, and he walked back down to Korphe, " Mortenson says.

“你让所有人都疯了。” “然后他伸出手拿走了我的铅垂线、水平仪账簿，然后他走回科尔飞，”摩顿森说。

To ensure that the shafts were vertical, Romans hung a plumb line from a rod placed across the top of each shaft and made sure that the weight at the end of it hung in the center of the shaft.

为保竖井垂直，罗马人在横跨每个竖井顶部的杆上悬挂一条铅垂线， 并保其末端的重物悬挂在竖井的中心。
