土星

But from our earthbound perspective, the tilt of Saturn's rings does change with time.

但从我们地球的视角来看，土星光环的倾角始终在不断变化中。

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。

Features on the Saturn moon Enceladus are named for characters and places from the classic literary work Arabian Nights .

特点对土星月球土卫二被命名为字符和地方从经典的文学作品天方夜谭。

Instead, the only way sodium can exit Enceladus is for the element to escape from the moon's interior.

但是现在，Kempf和他的研究小组可以确定这些钠元素来源于土星 E环。

Explanation: What does the surface of Saturn's ice-spewing moon Enceladus look like?

说明：土星卫星土卫二有冰渗出的表面看起来会是什么样子？

The Voyagers showed that the diameter of Enceladus is only 500 km , about a tenth of that of Saturn's largest moon, Titan , and reflects almost 100% of the sunlight that strikes it.

在旅行者表明，土卫二的直径只有500 公里左右的土星最大的卫星土卫六，是第十届，并反映了近100 阳光的打击它。

Enceladus' icevolcanos also likely produce Saturn's faint but extended E ring.

土卫二的冰火山可能也造成了土星昏暗、广大的E环。

The missing link, he adds,"is whether the sodium in the E-ring particles really came from Enceladus."

而最后，这些固态的钠元素将重新和土卫二的喷发物融合在一起并继续存在于土星E环中。

Enceladus' ice volcanos also likely produce Saturn's faint but extended E ring.

土卫二的冰火山可能也造成了土星昏暗、广大的E环。

However, for Enceladus to still be active, part of the core must have melted too, forming magma chambers that would flex under the strain of Saturn's tides.

然而，土卫二的仍然是积极的，核心的部分也必须融化，形成岩浆商会将在土星的潮汐应变弹性。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
