土卫一

The shadows of Titan and Mimas have both moved off the right side of the disk.

土卫六和土卫一的阴影都在盘面的右侧移动。

To the human eye, Mimas would likely be a uniform gray.

要是用人的肉眼来看土卫一的话，它可能会是全灰色的，但这张照片上的颜色非常的夸张。

Small moon Mimas is just touching Saturn's disk near the ring plane at the far right.

土卫一位于最右侧光环附近，紧贴着土星盘面。

For instance, a particle at the outer edge of Saturn's B ring is in a 2: 1 resonance with Mimas, meaning that it goes around the planet precisely twice for each lap the satellite completes.

例如，土星B环外缘的粒子与土卫一周期成2：1共振，意思是粒子每绕行星两圈，卫星刚好绕一圈。

The outer edge of the B ring which forms the inner boundary of the Cassini division is maintained by a gravitational resonance with Mimas. Near the outer edge of the A ring are the Encke Gap (325 kilometers, or 202 miles wide) and the barely visible Keeler Gap (35 kilometers, or 22 miles wide).

形成卡西尼环缝内缘的B环外侧的形状由其与土卫一的引力共振保持。A环外侧是恩克缝（宽325公里，202英里）和勉强能看到的科勒缝（宽35公里，22英里）。

Cassini came within about 5,900 miles of Mimas and these images were obtained with Cassini's narrow-angle camera on that day at a distance of approximately 10,000 miles from Mimas.

NASA/JPL/Space Science Institute 在这个2010年2月13日飞越，卡西尼号在大约5，900米玛斯来到英里和获得这些图像与卡西尼号上的窄角相机距离土卫一上的10000天在大约距离。

A high-resolution closeup of Saturn's moon Mimas shows mysterious color differences around the huge Herschel crater. The combined picture, released March 29, 2010, is based on several shots taken by NASA's Cassini orbiter during its closest ever flyby of the tiny moon in February.

这是土卫一的一张高清特写照片，清晰的显示了巨大赫歇尔陨石坑周围不同颜色的神秘性。2010年3月29日美国宇航局公布了这张照片，它是由卡西尼号探测器于今年2月份飞过这颗卫星时，所拍摄到的几张照片拼合而成。

From their very low densities and relatively high albedos, it seems likely that Prometheus, Pandora, Janus and Epimetheus are very porous icy bodies.

从它们很低的密度和相对较高的反照率来看，土卫十六，土卫十七，土卫十和土卫十一可能是多孔的冰质天体。

In a companion paper, Dr Dale Cruikshank of NASA 's Ames Research Center and colleagues report that Hyperion's surface is quite reflective but the bottoms of the craters are quite dark, similar to those found on the Saturnian moons Phoebe and Iapetus.

在一篇相同主题的论文中，美国航空航天局艾米研究中心的戴尔·克鲁克香克博士及同事报道，土卫七表面反光性相当好，但陨石坑的底部很黑暗，类似在土卫九和土卫八上发现的陨石坑。

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。
