The finite element method was applied to calculate the potential distribution and current distribution on a cathodically protected steel pipe pile. In the calculations, the pipe pile, includion both the submerged and buried sections, was considered as a whole.

把钢管桩作为一个整体，用有限元法计算了几种条件下的电位分布和电流分布情况，讨论了水的电阻率、表面涂层、阳极与钢管桩的距离以及阳极长度等因素对电位分布的影响。

Lastly, the demagnetizable method to high-speed moving steel pipe is researched and the discrete time method is used to explain the demagnetizable processing of steel pipe.

提出了采用时间上离散化的退磁过程分析方法，很好的解释了钢管的退磁过程，解决了钢管高速运动中的退磁问题。

Some modern drilling rigs have automated pipe-handling equipment such that the derrickman controls the machinery rather than physically handling the pipe.

有的现代钻机拥有自动化的处理钻杆的设备，因此，井架工就只需要控制机器，而不是亲自用力去操作管柱。

In a typical trip out of the hole, the derrickman wears a special safety harness that enables him to lean out from the work platform to reach the drillpipe in the center of the derrick or mast, throw a line around the pipe and pull it back into its storage location until it is time to run the pipe back into the well.

在典型的起钻过程中，井架工系上特殊的安全带，这样能够使他从工作平台上倾斜去接近位于井架或者桅架中央的钻杆，扔一根绳子去缠绕钻杆，然后拉动钻杆到其存储的位置，直到再把这些钻杆下入到井眼时为止。
