New horizons is being pulled by jupiter ' s gravity to a greater speed toward its next target : pluto in 2015 新地平线号将受到木星引力的牵引，加速往它的下一个目标：冥王星前进，预计2015年可抵达。
As the moon ' s gravity is only about 1 / 6 the gravity of the earth , a 200 - pound man weights only 33 pounds on the moon 由于月球的引力只有地球引力的六分之一，所以一个体重200磅的人在月球上仅重33磅。
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。
At the same time , the conception of gravitation is used to find the path , which can help ants find the aim more quickly 同时本文在路径搜索过程中引入了引力的概念，使得蚁群在引力的作用下以较快的速度找到目标端点。
Satellites , however , must be closely watched , for they are constantly being tugged at by the gravitational attraction of the sun , moon and earth 由于经常受到太阳、月亮和地球引力的影响，卫星活动必须加以密切的观察。
The tremendous gravity of the black hole , estimated to have a mass 100 million times that of our sun , then stretched the star to the point of breaking 黑洞巨大的引力随后把恒星不断拉伸直到破裂，黑洞的引力估计是太阳引力的1亿倍。
As a result , it will be necessary to find a way by which we can calculate the disturbing gravitation exactly and fast 因而，如何修正扰动引力的影响，尤其是要适应快速机动的发射要求，就需要寻求一种快速精确的计算地球外部空间扰动引力的方法。
Black holes smaller than this limit can only be created if their matter is subjected to sufficient pressure from some source other than self - gravitation 如果它们的物质受制于来自胜于自我引力的一些足够大压力其它来源，只能产生比这个界限小的黑洞。
Either there was some huge but unseen mass that was doing the job , or gravitational theory was wrong and gravity worked differently on cosmic scales 或者是存在一大团不可见物质填补了引力的不足，或者是引力理论出了错，况且引力在不同宇宙尺度上产生的作用不一样。
Either there was some huge but unseen mass that was doing the job , or gravitational theory was wrong and gravity worked differently on cosmic scales 要么就是存在一大团不可见物质填补了引力的不足，要么就是引力理论出了错，即引力在不同宇宙尺度上产生的作用不一样。
