1·Rotate the gyro ball continually along vertical axis.

把陀螺球绕垂直轴连续地转动。

2·The gyro vertical utilizes a gyroscope as an integrating device to obtain the average position of a pendulous gravity reference .

垂直陀螺利用一个陀螺仪作为积分装置以得摇摆不定的重力基准线的平均位置。

3·T should not be made larger than necessary since excessive erector damping causes the gyro to overshoot the vertical during erection.

t也不应该做得比需要的更大，因为修正装置阻尼过大将使陀螺在修正过程中偏离垂线过多。

4·The input axis of the azimuth gyro under this condition is vertical, and pendulum unit is nulled.

在这样情况下方位陀螺的输入轴是处于垂直位置，同时摆锤单元在零位。

5·Near-vertical wells have no reference to the high side of the well rendering inclinometers ineffective. To facilitate accurate gun positioning an oriented gun hanger would need to be set using a gyro.

由于倾角仪在这种接近垂直的井中会失去效果，故工具无法参考其朝上的那端来做射孔方向定位。
