He also figured out the planet goes faster when it's at perihelion, nearer the sun, than when it's at aphelion, its farthest distance-which would explain why summer seems to zip by , except the seasons are a function of the tilt of the Earth's axis, not its different distances from the sun.

他还计算出地球在近日点时运行速度，比在远日点更快，这就可以解释为什么夏天好像比较短，另外，季节与地球轴的倾斜相关，不是因为地球与太阳距离远近的不同而造成的。

It is even possible to envision the world so wryly and chillingly prophesied by the typewriting cockroach in Donald Marquis' archy and mehitabel: man is making deserts of the earth/ it wont be long now/ before man will have it used up/ so that nothing but ants/ and centipedes and scorpions/ can find a living on it.

甚至可以想象世界在唐。马奎斯的《archy and mehitabel》中，被蟑螂如此冷淡的预言：人类在地球上制作沙漠/在人类将地球资源耗尽之前不会太久了/因此只有蚂蚁，蜈蚣和蝎子能够在地球上生存。

The Astrochemistry Laboratory researches on extraterrestrial materials and especially the formation, distribution, and fate of organic compounds (comprised primarily of carbon, like those in living things), space environments including interstellar, cometary, and planetary ices, extraterrestrial organic molecules that made the Earth habitable and may have even been involved in the origins of life.

天体化学实验室主要研究地球外物质，尤其是有机化合物（主要组分是类似生命物质中的碳）的形成，分布以及结果，空间环境，包括星际的，彗星的，和行星的冰层，以及那些使地球可居住和可能参与生命起源的地球外有机分子。

This is because of its history, where various groups involved themselves in guiding Earthlings at various times.

这是因为地球的历史，在地球历史上有各种群体参与进来指导各个时期的地球居民，就如在即将来临的大转变期间，是哪一个群体在影响着对人类的拯救是无关紧要的。

According to Biot-Savart law, the magnetic induction at the diameter position of the spin axis is calculated. Furthermore, using the internal and external radius of the Earth's outer core as well as the radius of the Earth and the magnetic induction at the Earth's magnetic pole, the volume charge density and surface charge density of the Earth's outer core have been obtained.

先根据毕奥-萨伐尔定律计算球形模型绕自转轴旋转时在自转轴直径上产生的磁感应强度；再利用已知的地球外核的内外半径及地球半径和磁极处的磁感应强度值，计算出地球外核的电荷体密度及面密度。

For example,did you know that if the earth were just a tiny bit closer to the sun,we'd all burn to death, or if it was just a tiny bit farther away from the sun, we would all freeze to death.

举例来说，你知道吗，假如地球距太阳只要稍微近一点，我们就会被烧死；假如地球地球稍微离太阳远一点，我们就会被冻死。

Earth's collision with another large celestial body after much of the Earth's iron fell to its core.

其他的理论家提出，在地球的大部分铁沉入到地核之后，由于地球与另一个庞大的天体发生碰撞，月亮便从地球那石质的地幔中撕裂开来而形成的。

Digital earth, emerged at the end of last century, is a new strategic orientation for quantitatively studying the earth and a crosscutting multidisciplinary field of space science and technology, information science and technology, earth science etc.

数字地球是20世纪末期问世的定量化研究地球的一个新的战略方向，是集空间科技、信息科技、地球科学等于一体的交叉学科领域。

It to study the application of satellite motion theory and satellite observations, to solve the Earth's surface point position, shape of the Earth, the Earth elevation, location of plate movement and other issues involving , motion, deformation and gravity field, the creation of satellite geodetic network as the state's basic control network.

它研究应用卫星运动理论和卫星观测，解决地球表面点位置、地球形状、地球高程、板块运动等涉及位置、运动、形变以及重力场的问题，建立卫星大地网作为国家基本控制网。

Earth because the Moon has just been caught near the Earth, the Earth in six plate gravitational pull of the moon, a strong collision, the crustal rocks in the hot rolling-out with the ice water for drastic changes in the physical and chemical.

因为月球刚被地球捕获，距离地球近，地球上6大板块在月球拉引力作用下，进行强烈碰撞，让地壳中火热的岩铁浆流出来，与冰水进行剧烈的物理和化学变化。

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。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
