| 1. | Two perpendicular lines are chosen as the x and y coordinate axes .
选两条垂线作为x和y坐标轴。 |
| 2. | Draw a line perpendicular to the horizontal axis through the point .
通过这两直线的交点做横轴的垂线。 |
| 3. | As n increases, the vertical lines not only become more numerous but also tend to bunch up together to form a bell shape .
当n增加时，不仅垂线愈来愈近，而且趋向于钟形曲形。 |
| 4. | 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。 |
