引力

The key is that we used the centrifugal force produced by whirlpool to break loose from gravity. Get it?

关键在于我们借助了旋涡的引力使我们获的了挣脱了旋涡的巨大惯性，你们明白了吗？

The Canis Major dwarf galaxy is not faring well in its gravitational battle with the Milky Way, and there are streamers of stars being pulled off the smaller galaxy onto the disk of our own.

Canis Major星系在与我们的银河的引力之争中处于劣势，已经有一条由被拖出的恒星的彩带被从Canis Major拉出，并被引入银河系大圆盘中。

It is similar to the force that causes a liquid to rise in a capillary tube - the capillary attraction, or capillarity.

这是内聚力作用于液体表面的结果；正如引起液体沿毛细管上升的毛细引力。

At the center of the track was a variable gravity drain that would catch fallen riders.

Real celestial mechanics background of the sun,the earth and the moon is considered.

给出了太阳引力摄动下地月会合坐标系绝对角速度的简单但精确的表达式。

This problem, which was certainly known to the ancients, became especially acute in the seventeenth century with the invention of celestial mechanics, which first gave philosophers a certain picture of a way the world might be: it might be a world whose future states were entirely determined by the past and the laws of nature (of which Newton's laws of motion and law of universal gravitation served as paradigms).

这个从很早就被知道的问题，在十七世纪之后变得尖锐起来，因为引力力学第一次给予了哲学家一个明确的世界图景：可能世界的未来事态完全可以被过去和自然律（Newton的运动律和万有引力定律是范例）所决定。

A black hole, like theone in Centaurus A, is formed when a massive star collapses from itsown gravity.

黑洞， 像在半人马座A星系的这一个，是当一个质量大的恒星因为自己的引力而塌缩后形成。

What is the center of gravity?

地球引力的中心是什么？

Challenges are gifts that force us to search for a new center of gravity.

挑战是强迫我们寻找新的引力中心的礼物。

"This changes the mother's center of mass, which is a critical point in any three-dimensional body on which gravity acts."

"这改变了母亲的身体中心，这在地球引力作用于任何三维身体上是非常重要的一点。"

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。
