地球

Venus is the easiest planet to identify since it is, after the Sun and the Moon, the brightest object in the sky; it is a brilliant yellow-white in color and can be observed even in daylight.

其颜色呈鲜明的黄白色，即便是在白天也能看到。从地球上观察时，我们发现，金星像月球一样有一个新月期：距地球最远时，它看起米非常小；当它靠近地球时，它就会变大。

But as industry booms on earth, greenhouse gases, like carbon dioxide and methane, are released into the air—and trap more and more of the sun's energy in, so the earth's temperature rises.

但是由于地球上工业的迅速发展，诸如二氧化碳和甲烷之类的温室气体被释放到空气中――从而又把越来越多的太阳能聚集回地球，地球温度因此而升高。

A: There are no planetary alignments in the next few decades, Earth will not cross the galactic plane in 2012, and even if these alignments were to occur, their effects on the Earth would be negligibles Each December the Earth and sun align with the approximate center of the Milky Way Galaxy but that is an annual event of no consequences

回答：在以后的几十年中，没有小行星连成一线的现象发现，地球也不会在2012年穿过银河系水平钱，就算是被排成了一条直线，对地球的影响也是可以忽略不计，每年的12月份，太阳、地球都会与银河系的近似中心连成一线，但并没有造成过什么影响。

He also figured out the planet goes faster when it's at perihelion, nearer the sun, than when it's at aphelion, its furthest 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。

The authors find coupling mechanism of momentum of nutations between solar and earth. It is caused by solar radiation, earth's rotation and revolution, angle between ecliptic and equator, irregularity of oceans and continents between northen hemisphere and southen hemisphere and layer structure of earth's core.

作者发现：太阳辐射，地球自转与公转，黄、赤交角的存在，陆地和海洋在地球表面南、北半球的不规则、不对称地理分布，及地球内部因〖ZZ〗形成的分层结构，构成了一套天然的能使地球产生自由章动的日、地间动量相耦合的物理机制。

And the earth and moon all run in the big temperature of the sun.

而地球和月亮都是运行在太阳的大温度下，你要是想算月亮相对地球的温度就把月亮当0，地球当1，用月亮相对与太阳的温度除以地球相对与太阳的温度。

In the 90's geoscientists both at home and abroad have applied the modern sophisticated methods and techniques in geoscientific research.

90年代，国内外地学工作者将现代科学的新方法、新技术应用于地球科学研究中，通过深海钻探、高温高压技术与地球物理手段等多种方法综合研究，致使在：地球的核-幔组分；CO2的起源、全球变化及其与成矿的关系；岩石圈的演化与缺氧事件、生物灭绝、海底扩张及成矿的相关性等诸多固体地球科学研究领域，均取得了若干最新的认识和重要进展。
