| 1. | Angles are measured clockwise when looking along the rotation axis toward the origin
角度按照沿旋转轴向原点方向看的顺时针方向测量。 |
| 2. | Material along the rotation axis falls vertically toward the equatorial plane much faster
沿著转轴两侧分布的物质则快速笔直地落入赤道面。 |
| 3. | Angles are measured clockwise when viewed from the rotation axis positive side toward the origin
角度按照沿旋转轴（正面）向原点方向看的顺时针方向测量。 |
| 4. | Place the 3dcursor at the position through which the rotation axis must pass . such an axis will be vertical
放置3d光标在你要作为旋转轴的位置，轴是垂直的。 |
| 5. | When swinging transmission machine operation , the force constant rotation axis to make efforts before and axial rotation move backward
当摇摆传动机械运行时，等速旋转入力轴使出力轴向前和向后旋动。 |
| 6. | For those who haven ' t heard the word , " precession " is when an object with a nonspherical shape wobbles around its rotation axis
如果你还不了解“进动”这个词，进动指的是物体绕它的旋转轴有非球形的摆动。 |
| 7. | Precessing stars do radiate gravitational waves , but they ' re not the only ones . any asymmetry about the rotation axis will do
进动的星体确实会辐射引力波，但它们并非唯一的选择。绕旋转轴的任何不对称都会导致引力波的产生。 |
| 8. | As the earth spins on its rotation axis , it wobbles like a top , slowly swinging the northern hemisphere closer to and then farther from the sun
当地球自转时，自转轴会像陀螺一样晃动，因此北半球与太阳的距离会逐渐接近，继而远离。 |
| 9. | Material in the equatorial region of the cloud ? that is , in the plane perpendicular to the rotation axis ? moves inward more and more slowly as rotation starts to balance the pull of gravity
当转动开始与重力的向内拉力平衡时，位在整团云气的赤道区域，垂直于转轴的平面上的物质，会逐渐减缓向内移动的速率。 |
| 10. | Made in the rotation axis , dividing machinery to stop transmission . at this point , the operator may decide indexing products position , and began fabrication , assembly and testing needed for its action
在出力轴旋转后，分度传动机械停止。此时，操作者可决定分度产品的位置，并开始加工、装配和检验，作其需要之动作。 |
