gravitational attraction

Satellites , however , must be closely watched , for they are constantly being tugged at by the gravitational attraction of the sun , moon and earth .

因为经常受到太阳、月亮以及地球引力的影响，卫星勾荷戈需加以慎密亲密的不雅察看。

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。

Which of them show the effect of gravitational attraction ?

以下哪项显示地心引力的效应？

The gravitational attraction between two objects is affected by intermediary between them .

两物体间的“万有引力”与它们之间的中介物质有关；

So , he was able to explain this using his laws for gravitational attraction .

他根据自己提出的万有引力定律，解释这一定律。

The force of gravitational attraction between two bodies decreASe AS the distance between them increASes .

两物体之间的引力随着两物体之间的距离增大而减小。

Gravitational attraction would pull them into a sphere .

在重力的作用下，它们会慢慢聚集成一个球体。

If you treble the distance , the gravitational attraction gets nine times weaker .

如将距离增大两倍，则其万有引力就减小九分之八。

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。

Is that causes by gravitational attraction ?

这是由万有引力作用产生的吗？

And we have also seen gravitational attraction in space , and I will let you look at your notes for that .

我们还学习过空间中的万有引力，关于这个知识点，大家翻一翻笔记。

In regions of slower expansion , the gravitational attraction of the matter , would slow down the expansion still further .

在扩张较慢的地区，物质的万有引力将进一步减缓扩张。

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。

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。

But if the field changes or oscillates quickly enough , it produces a gravitational attraction , just like ordinary or dark matter .

不过，要是纯量场变化或是振得够快，它就会产生重力相吸效应，一如普通物质或是暗物质。

One of them is what curl says about force fields and , in particular , a nice consequence of that concerning gravitational attraction .

其中之一是从旋度的角度，来观察力场，一个关于万有引力的漂亮的结论。

The dynamics of the Earth-Moon system is quite different from the Sun-Earth system especially after a long duration for the gravitational attraction of the Sun .

由于在地-月系统中太阳的引力不可忽略，特别是在长时间作用以后，其动力学行为与摄动力较小的日-地系统有明显的不同。

It exerts a strong gravitational attraction on anything near it , so that we would have to prevent ourselves from being eaten alive by it .

它对靠近它的一切东西施加一种强大的吸引力，所以，我们必须防止被黑洞活生生地吃掉。

Tides are caused by gravitational attraction of the sun and moon ; the weather by the motion of atmosphere under the influence of heat from the sun .

潮汐是由太阳和月亮的重力吸引所致；而天气则是因太阳的热量影像大气运动而形成的。

It 's the gravitational attraction between the sun and the planets that sustains the planets in elliptical orbits around the sun .

那是太阳和行星之间的万有引力。维持着众行星围绕在太阳四周的椭圆轨道上。

Gravitational attraction is an equivalent expression of the force close to each other between and on the line of the two objects , coming from exchange of momentum between objects and micro-particles .

“万有引力”是物体与微粒子的动量交换在两物体连心线上产生相互靠近的力的一种等效表达；

Physically , the cosmological term would have been unobservable on the scale of our solar system , but it would produce a cosmic repulsion on larger scales that would counteract the gravitational attraction of distant objects .

实际上，宇宙项在太阳系的尺度是观察不到的，但是它在大尺度下会产生一种宇宙排斥力，抵消了相隔很远物体之间的引力。

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。
