| 1. | They were also used, for example, to determine the gravitational attraction exerted by a lamina on particles .
例如：他们也用来确定一个薄片作用在一个质点上的万有引力。 |
| 2. | The gravitational attractions of the pieces of dust for one another might make them form little lumps .
尘埃片与片之间由引力而产生的吸引，可能会使它们形成一些小的团块。 |
| 3. | The components of most double stars are close enough for there to be strong gravitational attraction between them .
大多数双星的子星都很靠近，所以它们之间存在很强的万有引力。 |
| 4. | A body subjected to gravitational attraction by the earth and orbiting the latter according to the law of celestial mechanics must be termed a "celestial body" .
一个受到地球引力吸引，并按照天体力学定律环绕地球运转的物体必须叫做“天体”。 |
| 5. | The craft will acquire sufficient velocity to escape the sun ' s gravitational attraction
飞船将会以足够快的速度来脱离太阳的引力。 |
| 6. | At the beginning of the formation of a star , the gravitational attraction will pull the gas together
在一颗恒星形成初期，引力是演化的主导力量，令恒星不断收缩。 |
| 7. | Its gravitational repulsion would offset galaxies ' gravitational attraction , thereby deadening their motion
暗能量的斥力会抵消星系间的引力，从而减弱了星系的运动。 |
| 8. | The gravitational attraction of the extra matter in those regions , would slow down their expansion , and eventually stop it
在那些地区,多余的物质会产生向内的引力,使其扩张减缓并最终终止。 |
| 9. | Many asteroids are weakly bound piles of rubble , held together by their own minute gravitational attraction
大多数的小行星都是由碎石组成，而这些碎石靠着自身之间微弱的万有引力结合在一起。 |
| 10. | 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。 |
