土卫一

From left, the moons visible here are Janus (181 kilometers, or 112 miles across) and Mimas (398 kilometers, or 247 miles across).

从左至右，两颗卫星分别是土卫十-Janus（直径181公里，112英里）和土卫一-Mimas（直径398公里，247英里）。

Hedman and his collaborators also have found that the moonlet's orbit is being disturbed by the larger, nearby moon Mimas, which is responsible for keeping the ring arc together.

Hedman 和他的同事们还发现这颗小卫星的轨道受到了临近另一颗较大的卫星土卫一的影响，它的作用使环弧得以保持聚集。

The above movie was centered on Saturn's moon Rhea, so that the moons Mimas and Enceladus appear to glide by.

上面这幅电影是以土卫五为中心，所以土卫一和土卫二看起来会飞掠而过。

This movie still captures the moons Mimas,Enceladus, and Dione as they begin their race across Saturn's disk.

本段视频是土星的几个大卫星在土星光环附近赛跑的截图片段（应该说这些是原始图像才对——译注），这三个卫星是土卫一、土卫二和土卫四。

"Mimas looks like, ah, a natural version of the Death Star in Star Wars because one of its surfaces is almost completely dominated by a giant crater. Ah, had...the object which caused the crater been slightly bigger, Mimas would have been totally destroyed, and by now, it would have been assimilated into Saturn's rings."

"土卫一看上去简直就像是电影星际《星球大战》中的死星的原型，因为它的其中一面几乎完全被一个巨大的陨石坑所占据，如果造成这个坑洞的物体再大一点的话，土卫一就会完全被摧毁并被吸入土星的光环中。"

Dione is on the far left of the image, Mimas is in the middle, andEnceladus is on the right. Dione and Enceladusare casting long shadowson the rings.

在图中，土卫四位于最左下方，中间的是土卫一，土卫二在右方。

For example, Saturn's E ring reaches across a broad region that encompasses the satellites Mimas, Tethys , Dione and Rhea, peaking in brightness at the orbit of the smooth, icy moon Enceladus.

例如，土星的E环所跨过的一大片区域中，包含了土卫一、卫三、卫四与土卫五等卫星，亮度的最高峰就处于平滑冰冷的土卫二之轨道上。

Carl Murray, a Cassini imaging team member and professor at Queen Mary, University of London, said, The moon's discovery and the disturbance of its trajectory by the neighboring moon Mimas highlight the close association between moons and rings that we see throughout the Saturn system.

伦敦大学 Queen Mary 学院的卡西尼成像小组成员 Carl Murray 说：此次卫星的发现以及其轨道距离土卫一轨道之近凸显了我们看到的土星系中卫星和光环之间的紧密联系。

During the flyby, Cassini also captured the highest-resolution temperature map of Mimas, revealing an unexpected pattern of warm regions reminiscent of the arcade icon Pac-Man .Published March 30, 2010

在卡西尼号此次掠过土卫一飞行期间，它还捕获了土卫一高清晰的温度图谱，可以揭示其温暖地区令人意想不到的模式，而这张图能令人回忆起幼时常玩的"吃豆小精灵"。

The image captures Saturn's majestic rings from the side of the ring plane opposite the Sun -- the unilluminated side -- another vista not visible from Earth.

照片中的许多细节令人称奇，例如土星云带的微妙色彩，土星映在环上的影子，以及土卫一、土卫十和土卫十七。

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。
