土星

The movie then zooms back into the system to show the orbit of the moon Iapetus in blue.

视频接着回到蓝色的土卫八轨道展示了土星系统。

Both the ring and Phoebe orbit in the opposite direction of Saturn's other rings and most of its moons, including Titan and Iapetus.

新环和土卫9的运行方向与土星主光环以及包括较大的土卫六和土卫八的大部分卫星的方向相反。

The ring is circling in the same direction as Phoebe, while Iapetus, the other rings and most of Saturn's moons are all going the opposite way.

环是绕在同一方向的菲比，而土卫八，其他环和土星最大的卫星都是走相反的方向。

The image was acquired during Cassini's only close flyby of Iapetus, a two-toned moon of Saturn.

在卡西尼航天器航天器非常靠近Iapetus的宇宙飞船过程中，拍下了这张照片，Iapetus是土星的双色调月球。

"Astronomers have long suspected that there is a connection between Saturn's outer moon Phoebe and the dark material on Iapetus," said Hamilton.

"天文学家长期怀疑有某种联系，土星的卫星外菲比和黑暗物质的土卫八，"汉密尔顿说。

The pictures of Saturn, Phoebe and Iapetus were taken by NASA's Cassini spacecraft.

土星、土卫八的图像来自卡西尼探测器。

This is a raw image taken by the Cassini spacecraft during its close fly-by of Saturn's moon Iapetus, Sept.

这是一张绕土星飞行的自然卫星--爱泼特斯卫星的原始图像。2007年9月10日，卡西尼太空飞船在飞过爱泼特斯卫星时拍摄到的。

The orbit of Iapetus is also unusual, being tilted to the plane of Saturn's orbit by an unusually high fifteen degrees.

Iapetus还有其他无法解释的特征：Iapetus的发光部覆盖着无法说明的细长的经脉；Iapetus的运行轨道也很奇特，相比土星轨道平面，异常的高了15度。

"Astronomers have long suspected that there is a connection between Saturn's outer moon Phoebe and the dark material on Iapetus," said Hamilton."This new ring provides convincing evidence of that relationship."

汉密尔顿说："天文学家一直怀疑存在一个连接土星的外围卫星——土卫九与土卫八上黑暗物质之间的纽带，新环就提供了这个联系的证据。"

Saturn went retrograde on December 31, 2008, but will turn direct on May 16 and stay in fine form from now on.

土星于2008年12月31日起逆行，但会在5月16日起恢复正常。

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。
