土卫一

Another of Saturn's moons, Enceladus, which is home to geysers that spew ice, will also be explored in detail.

土星的另一颗卫星——土卫二是喷冰的喷泉所在之地，也会得到详细的的探测。

Images of a crescent Enceladus returned by Cassini this past weekend show multiple plumes in striking detail.

一新月形的土卫二的图像由卡西尼在这个过去的周末展示多醒目细节。

This discovery, along with the presence of escaping internal heat and very few impact craters in the south polar region, shows that Enceladus is geologically active today.

这一发现，随着逃避内部的热量，很少存在（如果有的话，在南极地区）陨石坑表明，土卫二是地质活动今天。

Iapetus has a strange appearance -- one side is bright and the other is really dark, in a pattern that resembles the yin-yang symbol.

土卫八有一个奇怪的外观-一边是光明的，另一种是非常暗，在一个模式类似於阴阳符号。

Astronomers think it is possible that the new found ring, which orbits in the opposite direction of Iapetus, is the cause of the two-faced coloring.

天文学家猜测与土卫八逆向运行的新光环能解释这个卫星两面颜色不同的原因：就像虫子落在挡风玻璃上一样，环中的冰粒也会溅落在土卫八的一面上。

Years after Giovanni Cassini discovered Iapetus in 1671, he correctly deduced that one side of the moon is white and the other dark in a pattern that some say resembles the yin-yang symbol or a tennis ball.

自1671年乔凡尼·卡西尼发现土卫8以来，他就正确指出这个卫星一面是白的一面是暗的，就像一条阴阳鱼或者一个网球。

The western hemisphere is dominated by a huge impact crater, called Odysseus, whose 400 km diameter is nearly 2/5 of that of Tethys itself.

它的西半球有一座巨大的称为Odysseus的由撞击产生的陨石坑，它的400千米的直径相当于土卫三本射的40％。

A Subtle Difference -- Subtle color differences on Saturn's moon Mimas are apparent in this false-color view of Herschel Crater captured by NASA's Cassini spacecraft during its closest-ever flyby of that moon.

一个微妙的差异-的月亮土卫细微颜色差异明显的土星是陨石坑在赫色鉴于此假飞船捕捉到美国宇航局的卡西尼号在其最接近的一次飞越该卫星。

Analysis of the outgassing suggests that it originates from a body of sub-surface liquid water , which along with the unique chemistry found in the plume, has fueled speculations that Enceladus may be important in the study of astrobiology .

对除气分析表明，它源于一分体表液体水，而随着中的独特化学羽发现，有刺激猜测，可能是土卫二的天体生物学研究的重要。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
