Gear box is taken new structure of design , which can improve transmission accuracy and reduce tranmission noise efficaciously.

齿轮箱采用了定轴行星机构的新型结构设计，既提高了传动精度又有效地控制了传动噪音。

"If you don't have a Jupiter it's kind of hard to build a wet planet," Eisner said.

艾斯纳说：从某种程度上说，如果没有类木行星，就难以形成湿润的行星。

"The current numbers are suggesting 6 to 10 percent of stars have Jupiter-sized planets, which is exactly consistent with our findings," Eisner told SPACE.com .

"目前的数据表明，有6%至10%的恒星拥有木星大小的行星，这跟我们的发现恰好一致，"艾斯纳告诉《太空网》的记者说。

It was Newton who proved mathematically that the path of a planet must be an ellipse.

是牛顿用数学的方法证明了行星的轨道是一个椭圆。

An astronomical unit is the length of the semimajor axis of the orbit of a hypothetical planet of mass 1/354710sm and period 365.2563835 msd in elliptic motion about the Sun; that is

天文单位的定义改为：当公转周期为365.2568983263历书日时，一个假想的、质量为零的无摄动行星的椭圆轨道的半长径，等于一个天文单位。

This formation clearly depicts the elliptic orbit of a celestial body around the sun: we can conclude this from the fact that the sun is far out of the centre of the planetary orbit.

这形成清楚地描绘了一个围绕太阳天体椭圆轨道：我们可以得出一个事实，就是太阳，远远超出了行星轨道的中心这一点。

Occasionally, Pluto's highly elliptic orbit passes inside that of Neptune, making Neptune the furthest planet from the sun during these times.

有时，冥王星的高椭圆轨道内的传递海王星，使海王星离太阳最远的行星，在这些时间。

The sun isn't necessary the centre of the elliptic orbits of the planetary system.

太阳是没有必要的行星系统中心的椭圆形轨道。

Ellison, second richest man on the planet, am a college dropout, and you are not.

因为，我，埃里森，这个行星上第二富有的人，是个退学生，而你不是。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
