| 1. | At the event horizon , the escape velocity is equal to the speed of light
在活动视界里，逃逸速度等于光速。 |
| 2. | Escape velocity from solar system
脱离太阳系的速度 |
| 3. | Escape velocity from galaxy
脱离银河系的速度 |
| 4. | The buildup of pressure would force gas outward at speeds far above escape velocity
压力的增加，将迫使气体以远高于脱离速度的速率向外逃逸。 |
| 5. | At that time , the newtonian theory of gravity and the concept of escape velocity were well known
那时，牛顿引力理论和逃逸速度的观念是广为人知的。 |
| 6. | Because of gravitational attraction , the escape velocity at the surface of a star , say , will be higher if the star is smaller in size or heavier
恒星质量越大，体积越小，引力的羁绊便越大，所需逃逸速度亦越高。 |
| 7. | If the ices had been rapidly vaporized by an impacting object , the expanding gases might have helped the ejected fragments reach escape velocity
如果这种（永久冻结）冰由于物体的冲击力而迅速汽化，则形成的体积不断膨胀的气体可能有助于排出的碎片达到逃逸速度。 |
| 8. | Michell computed that a body 500 times the radius of the sun and of the same density would have at its surface an escape velocity equal to the speed of light , and therefore would be invisible
米切尔计算一个500倍太阳半径而且具有相同密度的物体就会具有它的表面逃逸速度等于光速,而因此不可见。 |
| 9. | When the escape velocity at a certain distance from the center reaches the speed of light , an event horizon is formed within which matter must inevitably collapse onto a single point , forming a singularity
当离中心某个距离的逃逸速度达到光速，形成一个活动视界，在里面的物质一定不可避免在单一点之上坍塌,形成一个奇异点。 |
| 10. | On the other hand , einstein discovered that the maximum velocity of any object is the speed of light . therefore , if the escape velocity on the surface of an object is greater than the speed of light , then nothing , including light , can escape from it
另一方面，爱恩斯坦的相对论断言宇宙中最高的速度便是光速，所以如所需的逃逸速度大于光速，那么宇宙中包括光在内的一切都不可能逃离引力的魔掌，这颗恒星便成为 |
