内行星

The two stars haven't moved; rather, you have changed the nature of space in the in-between region.

这两颗行星没有移动，但是在这段区域内的空间实质性的改变了。

But a handful of theorists already had a better explanation at hand. The giant planets could have formed in a much more sensible location, like Jupiter did, and then migrated inward, establishing a stable orbit there.

但很多理论天文学家对这种现象已经有了更好的解释：巨大的行星可以在更合理的位置先形成，就像木星那样，然后再向内迁移，最后定位于一个稳定的轨道。

Over break 3. But even assuming that a planet is the right size and has the proper chemical composition and a stable orbit neither too far from its star nor too close, so that its temperature is at all times in the range of liquid water (as is true of Earth except for the polar regions), a great deal would stilldepend on the kind of star it was revolving about.

Considering the many bright stars, nebulae, and star clusters in the region more familiar to skygazers, HD 189733 may not seem to be remarkable, but it is known to have at least one hot, jupiter-sized planet orbiting very close, with an impressively short period of 2.2 days.

在这个区域内，天空观测者们更为熟悉许多明亮的恒星，星云和星团，而HD189733可能不是那么显著，但是至少它是一颗炽热，木星大小的行星，轨道非常小，一个周期只需要2.2天时间。

At the heart of BMW′s Active Steering system is the planetary gear set incorporated into the steering column.

BMW主动转向系统的核心是内置在方向盘传动轴上的一个行星装置。

In this article , instead of changing the ubiety among the parts of the original elevator , the author keeps on using the original structure. However, because of the differences of the transmission ratio and speed, the author enlarges the planet gear, solar gear , thickness of the inner circle ring as well as the enclasping radius of the enclasping brake through the mechanical design and calculation .

在设计过程没有改变原有的升降机零部件的位置关系，但由于，传动比以及传动速度的不同，所以，通过受力分析计算，加大了行星齿轮、中心齿轮、内齿圈的厚度；同时也加大了抱闸抱紧时的抱紧半径。
