地球

If there were any inhabitants of the moon, they would see our earth reflecting the light of the sun, again like a huge mirror hung in the sky. They would speak of earthlight just as we speak of moonlight.

假如月亮上有居民，他们也会看到我们反射太阳光的地球同样就像一个巨大的镜子悬在空中，他们也会像我们谈论月光那样谈论地球光。

But the most striking thing is that Boriska thinks that now on Earth is the time when special children are being born because of some great changes to the planet, and new knowledge will be needed beyond the earthling mentality.

但是最震惊的事情是，鲍里斯卡想到，现在地球是在非常特殊的时期，因为将有一些很大的改变，就当如一个特殊的孩子正在分娩，一种新的知识将会超越现在地球的智力。

Astronomers hoping to study light from another Earth practice detecting clues to life in Earthshine (sunlight reflected off the Earth).

意译：天文学家希望去研究光源来自地球其它不同的实践线索，探索在地球反照学的生活。

If you're up before dawn, look at the waning crescent moon through binoculars. The soft, pale light illuminating the moon's nighttime side is called earthshine – sunshine that is reflected from Earth and back to the moon!

如果你在黎明时抬头，通过望远镜看新月，那的柔和的、洁白的光线照亮了月球的一边，这就被称为地球反照——太阳光被地球反射到月球。

Still, while the crescent Moonis overexposed, surface features can be seen on the dim lunar nightside illuminated by earthshine - light from sunlit planet Earth.

虽然下弦月的亮区过度曝光，但在地球反照光(被地球向日面所反射的阳光)的照耀下，可以清楚认出暗区的表面特徵。

In addition, the ring current is driven earthward (which energizes its particles further), temporarily modifying the field around the Earth and thus shifting the aurora closer to the equator.

此外环电流被逼近地球，进一步加强了其粒子能量，暂时地改变地球附近的磁场，使得极光向赤道靠近。

Using a one-dimension magnetic filament in the Earth\'s magnetotail to represent the bubbles,we examine the motion of bubbles created by reconnection in the Earth plasma sheet.Some properties of time evolution of the filament can be obtained from the numerical simulation.The magnetic field line in the filament created by reconnection is more dipolar than the surrounding magnetic field line,and the motion of the filament displays a strong earthward flow.The results show that MHD waves such as an Alfv?

本文研究地球等离子体片中重联后的磁泡的运动，用地球磁尾中的一维磁细丝来表示磁泡，通过数值模拟发现，重联产生的磁细丝磁场比周围磁场偶极性更强，运动时表现出了很强的地向流。

Its mean diameter is 3,475 kilometers (2,160 miles), its mass approximately one eightieth that of Earth, and its average period of revolution around Earth 29 days 12 hours 44 minutes calculated with respect to the sun.

它的平均直径为3，475公里2，160英里），它的质量约为地球的八十分之一，参照太阳，它围绕地球旋转的平均周期为29天12小时44分钟

Because of the ellipticity of the earth's orbit the solar radiation incident on the earth is about 7% greater in December than in June.

因为地球轨道是椭圆，入射到地球上的太阳辐射在12月份约比6月份多7％。
