habitable space

基本解释

According to one classic theory, the reason is simply that there is more habitable space around the equator than at the poles. On the face of it, this seems to make sense.
据常规判断，赤道地带比两极有更多的栖息地，表面上看这个原因很是合理。
The roof is separated from the ceiling of the habitable space to allow for constant ventilation and keep the heated material away from the interior, further helping to cool the space.
屋顶被居住空间的天花板隔开，允许持续通风并将吸热的材料远离室内，进一步帮助冷却空间。
The tropics encompass an area nearly five times the size of the Earth's polar regions, and there is some evidence that habitable space is correlated with the number of species on land.
热带地区有着比两极大五倍之多的生物可以生存的广泛地域，同时也有证据证明了陆地上的生物物种数量和可栖息地空间确实存在着某种联系。

However, since Ares I is capable only of reaching low Earth orbit and the space station is the only habitable thing in low Earth orbit, Ares I by itself would be a road to nowhere.

This past December, for example, NASA's Kepler space telescope confirmed its first planet in the habitable zone, a "super Earth" known as Kepler-22b that's thought to be 2.4 times as wide as our planet.
