| 1. | The law of conservation of angular momentum may be demonstrated with a gyroscope .
角动量守恒定律，可以用回转器来演示。 |
| 2. | The conservation of angular momentum takes exactly the same form and has the same significance in both domains .
角动量守恒在两种领域中形式完全相同，并且有同样的重要性。 |
| 3. | The conservation of angular momentum explains why disks are so prevalent in the universe
角动量的守恒解释了为什麽圆盘在宇宙中这麽普遍。 |
| 4. | Example : spinning up a charged cylinder . conservation of angular momentum and flux of angular momentum
23范例:旋转带电圆柱。角动量守恒及角动量之通量。 |
| 5. | This is understandable in terms of conservation of angular momentum . as the radius of rotation decreases , the rotational speed will increase accordingly
这现象可用角动量守恒定律来解释：当旋转半径缩短时，旋转速率就相应加快，以保持角动量不变。 |
| 6. | This is understandable in terms of conservation of angular momentum . as the radius of rotation decreases , the rotational speed will increase accordingly
这现象可用角动量守恒定律来解释：当旋转半径缩短时，旋转速率就相应加快，以保持角动量不变。 |
| 7. | It must then make fewer turns per second , in obedience to a law of physics called the conservation of magnetic moment ( this is similar to the law of conservation of angular momentum that slows a spinning ice dancer down as he spreads his arms )
服从称为磁矩守恒的物理定律，其会减少每秒旋转的次数（这一定律与角动量守恒定律很相似，花样滑冰舞者通过伸展自己的上肢来减慢自己旋转的速度就是利用这一原理） 。 |
