为了能够维持生命，这个新的星球不仅要有液态水，而且它的土表还必须是固态的，就像地球这样。
To be able to support life, the new planet would need not only to have water, but it would also need to be solid.
在土星最大的卫星土卫六上，科学家们发现其表面的布满液态甲烷的积洼，这些甲烷会造成有如豌豆汤一样的浓雾，而且气味更是糟到家了！
The scientists found that Titan, Saturn's largest moon, is covered with puddles of liquid methane, which give rise to a fog that's as thick as pea soup -- and smells a whole lot worse.
现在已有把二氧化碳变为合成气的工业生产，而且可以在同一个生产过程中继续把合成气转化为液态碳氢化学物。
Commercial processes are already available that use carbon dioxide to make a mixture called syngas, which can then be converted to liquid hydrocarbons in a process that can run continuously.
固体燃料火箭发动机的构造更简单、分量更轻，而且相对更安全。 在固体燃料火箭发动机里，燃料和氧化剂被预先混合成稳定的液态推进剂，然后被塞满火箭发动机的燃料箱里。
Solid-fuel rockets, in which the fuel and oxidiser are pre-mixed into a stable, solid propellant and then packed inside the case of the rocket, are simpler, lighter and relatively safer.
更重要的是，大脑似乎并不能像记录咀嚼所获得的能量那样精确地记录液态能量，而且不会发出停止吃东西的信号来使你不再摄入更多的食物。
What's more, the brain doesn't seem to register liquid calories as accurately as calories that are chewed, and it doesn't send stop-eating signals to keep you from eating more food.
它大概是地球质量的8倍而且它所在的轨道恰好有益于在其表面有液态水的存在。
It is about 8 times the mass of Earth, and located in an orbit just right for liquid water to exist on the surface.
而且有些研究者称液态水可能会定期形成于行星地表之下——由此可能为生命的生存提供了足够的立足点。
And some researchers say liquid water may periodically form just below the planet's surface - which may provide just enough of a toehold for life to survive there.
而且，这可以帮助他们研究火星上到底有没有液态的水。
It can also help them decide whether the planet had liquid water.
米利肯告诉《太空网》：“这些沉积层不但证说明了过去存在液态水，而且还说明液态水存在的时间很长，足以使某些岩石发生改变。”
And not only do the deposits indicate the past presence of liquid water, but that the water "was there long enough to alter some of the rocks," Milliken told SPACE. com.
人类的经验指出，液态水是生命的基本，而且水越多越好。
Human experience instructs that liquid water, preferably lot of it. is essential for life.
人类的经验指出，液态水是生命的基本，而且水越多越好。
