查询词典 Cassini

The measured value of unmodelled acceleration for Cassini is (26.7 ± 1.1)× 1010 m/s2, roughly three times as large as the Pioneer acceleration.

卡西尼号的额外加速度是(26.7 ± 1.1)× 1010 米/秒2 ，大致为先驱者号加速度的3倍。

Was when Cassini started to beam back its images from over a billion miles away.

是在卡西尼号从十亿英里之遥开始发送回图片之时

This would explain the moon's strange half-black, half-white appearance,first noted by Giovanni Cassini in the late seventeenth century.

这能解释这个卫星奇异的半白半黑的外貌，17世纪乔凡尼·卡西尼首先注意到这点。

The Cassini spacecraft has revealed a never-before-seen level of detail in Saturn's F ring, including evidence for the perturbing effect of small moonlets orbiting in or close to the ring's bright core.

卡西尼飞船显示出土星F环前所未见的细节，以及靠近或在环的明亮核心地带的小卫星造成的扰动证据。

She is a member of the UA-based Cassini VIMS team, headed by Professor Robert Brown of UA's Lunar and Planetary Lab.

她是受 Robert Brown 教授领导的亚利桑那大学月球与行星实验室、卡西尼 VIMS 小组的成员。

Using the K20 eyepiece included as standard equipment, about 45x magnification, it's easy to see the Andromeda Galaxy and its smaller satellite galaxy M32. When compared to 60mm refractors, the Powerseeker 114 brings out much more detail in the Orion Nebula, reveals many more stars in Perseus' Double Cluster and even brings out a few individual stars in globular clusters like M13. Saturn looks quite small at 45x with the K20 eyepiece, but using my own 7.5mm eyepiece (120x) I can easily detect the shadow cast by the planet on the rings, and even glimpse the ring's Cassini Division. When the mirrors are properly lined up or "collimated," the images are reasonably sharp up to magnifications of 225x.

使用标准配件中的K20 目镜，可以得到45倍放大率，这时候很容易看到仙女座星系，还有较小的星系M32；和60毫米口径的折射望远镜相比，114 EQ可以看清更多猎户座星云的细节；瞄准英仙座双星团，看到的星体数量更多，显得更加壮丽；对于球状星团，比如M13，甚至可以显出其中少数独立的恒星；在K20 目镜下（放大45倍）的土星显得相当小，但换成我自己的7.5毫米焦距的目镜(得到120倍)，可以轻松的看到光环在土星上的投影，甚至可以瞥见土星光环内的卡西尼缝隙。

Cassini has been orbiting Saturn since 1 July 2004 and is now in its Equinox mission phase that will see the giant planet experience equinox this August, the twice-yearly occasion when the Sun passes through the plane containing the planet's rings.

卡西尼号土星轨道已自2004年7月1目前已进入春分任务的阶段，将看到巨大的行星的经验春分今年8月，在每年两次的机会当太阳穿过飞机载有这个星球上的戒指。

卡西尼自2004年1月始环绕土星飞行，目前处于Equinox计划阶段。今年八月，卡西尼将要看到这个巨大行星经历昼夜平分点--太阳穿过这个行星环的平面时发生---此现象地球上一年发生两次。

The release of the new images coincides with the opening of a week-long celebration of the Cassini mission, which has been exploring the Saturnian for the last five years.

新图像的发布恰好发生在为期一周的庆祝卡西尼项目举行期间。项目在过去的五年中不断探索土星。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
