| 1. | Some bobs have a nut under them .
一些摆锤下面有螺母， |
| 2. | The mass of the pendulum bob does not change from one location to another on the earth's surface .
摆锤的质量在地面各处都一样。 |
| 3. | The hydrometric pendulum is sometimes used to determine flow velocities in open channels .
测流速的摆锤有时用于确定明渠中的流速。 |
| 4. | If the mass in question is a plumb bob, the horizontal component of f is important .
如果所讨论的质量是一摆锤，则重要的是F的水平分量。 |
| 5. | This is more feasible than altering the pendulous factor on a running compass .
对正在工作的罗盘来说，这样做比改变摆锤因数要更切合实际些。 |
| 6. | A bullet of mass m, traveling with a velocity v, strikes the pendulum and remains embedded in it .
质量为m的子弹，以速度v飞行，击中摆锤并嵌入其中。 |
| 7. | W is attached to a bar, movable vertically around an axis a and suspended by the helical spring f .
摆锤W装在一根杆上，在轴A周围垂直移动，它由螺旋弹簧F所悬挂。 |
| 8. | 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。 |
| 9. | When pulled to one side of its equilibrium position and released, the pendulum bob vibrates about this position .
把此质点作为摆锤拉到平衡位置的一侧，然后释放，摆锤就在平衡位置附近摆动。 |
| 10. | The pendulum output is divided, part going directly to the tilt-axis torques and another portion feeding the torques via a thermal integrator .
摆锤单元输出有讯号分成两部分，一部分直接输入倾斜轴力矩受感器，而另一部分通过热积分器后再送到力矩受感器。 |
