Y ou have not been able to rescue the environment y et , dematerialize the planet and not even feed the poor ones, because you have not been able to get rid of fear of shortage and a need to control others.

你们更加没有能够拯救行星的环境，消失行星甚至不供养贫穷的人，因为你们已经不能够摆脱短缺的恐惧而需要控制其他人。

Essential condition of the diagram to design the scheme was decided, and the methods to distinguish component attributes and to calculate planetary characteristic parameters were presented.

确定了设计多自由度复合行星传动方案应满足的必要条件，以及组成复合排的各构件属性判别方法和行星排的特性参数计算方法。

Keywords : compound planetary train;component relative rotational speed diagram;transmission scheme;design method

通过建立多自由度行星变速机构的构件相对转速图，提出了一种多自由度复合行星传动方案设计理论和方法。

The attraction of the other planets could then explain the deviation of the motion of the planet from the elliptic orbit.

其它行星的吸引可以用来解释行星运动椭圆轨道的偏离。

Astronomers led by Fritz Benedict and Barbara McArthur, of the University of Texas, Austin, examined the Earth's nearest known exoplanet neighbour—a gaseous giant orbiting the sun-like star Epsilon Eridani, 10.5 light years away in the constellation Eridanus.

在弗里兹·本尼迪特和芭芭拉·麦克阿瑟带领下，得克萨斯大学的天文学家们探测了一颗系外行星，这是已知的系外行星中离地球最近的一颗。

Along with its moon, Dysnomia, Eris is the most distant known object in orbit around the sun.

在太阳系的行星里，厄里斯星和它的卫星已知距离太阳最远的行星了。

All kinds of errors that influence load sharing characteristics of gear system have been given, mainly including manufacturing and assembly error of each gear component's axis and each bearing's axis, tooth thickness error. The formulas of equivalent mesh error have been derived.

确定了影响行星齿轮传动系统均载特性的各类误差，主要包括：各个齿轮构件的中心轴线制造和安装误差、轴承中心轴线的制造和安装误差、行星架的制造误差、齿轮的齿厚偏差。

So the planets kept on dancing to the math-music of the universe , and Lan's moon was admired by all ,until one day a evil-minded ice-hearted comet viciously slammed into it , shattering it into a thousand and thousand pieces .

行星们仍然随着宇宙的音乐舞蹈着，Lan的月亮被所有的行星所羡慕。直到有一天，一个恶意的冷酷的彗星邪恶地猛撞它，把它撞成了成千上万的碎片。

In the second test, the frequency response function is measured and the primary natural frequency has been obtained.

前者研究了不同转速下行星齿轮动态响应的频谱特性，后者则给出了行星齿轮传动的固有频率。

For instance, some systems could house only Earthlike planets and no gas giants, Gould said.

例如，有些系统可以在家中Earthlike行星，没有气体行星，古尔德说。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.
