光年

Discovery spent more than a week at the space station. Returning astronaut Timothy Kopra lived there nearly two months, while Buzz Lightyear logged 15 months.

"发现号"在国际空间站待了超过一个星期，将带回在那里生活了两个月的宇航员Timothy Kopra，而巴斯光年记录为15个月。

They might work at the happiest place on Earth, but Disney characters such as Mickey Mouse, Cinderella and Buzz Lightyear face more danger in the workplace than most of us, a new study reveals.

据一项新的研究表明，迪士尼卡通人物如米老鼠、灰姑娘和巴斯光年可能身处地球上最快乐的地方，然而和大多数人相比，他们在工作中面临着更大的危险。

The falling leaves beat our hearts piecemeally.that is the missing for the lightyear of the midsummer tour,or look forward to the winter snows.

秋天的落叶一片一片，不停敲动着我们的心弦。那是对盛夏光年的怀念，还是对寒冬白雪的期盼。

Meditations of evolution increasingly vaster: of the moon invisible in incipient lunation, approaching perigee: of the infinite lattiginous scintillating uncondensed milky way, discernible by daylight by an observer placed at the lower end of a cylindrical vertical shaft 5000 ft deep sunk from the surface towards the centre of the earth: of Sirius 10 lightyears (57,000,000,000,000 miles) distant and in volume 900 times the dimension of our planet: of Arcturus: of the precession of equinoxes: of Orion with belt and sextuple sun theta and nebula in which 100 of our solar systems could be contained: of moribund and of nascent new stars such as Nova in 1901: of our system plunging towards the constellation of Hercules: of the parallax or parallactic drift of socalled fixed stars, in reality evermoving wanderers from immeasurably remote eons to infinitely remote futures in comparison with which the years, threescore and ten, of allotted human life formed a parenthesis of infinitesimal brevity.

347关于宇宙日益扩大进化的冥想：新月期的月亮，即使在近地点也看不见。从地表向地轴挖掘纵深五千英尺的圆筒状垂直轴，一个观察者呆在轴底儿上，就连白昼也辨认得出那漫无止境、网络状、亮光闪闪、非凝结性的银河。天狼距地球十光年（五七、000、000、000、000英里）；体积大于地球九百倍；大角；岁差运动；有着"猎户"腰带、六倍于太阳的"伐二"以及星云的猎户座，星云中能容纳我们的一百个太阳系；死去的和新生的星宿，例如一九0 一年的那颗"新星"我们的太阳系正朝着武仙座冲去；所谓恒星的视差或视差移动，也就是说，实际上恒星是在不断地从无限遥远的太古朝无限遥远的未来移动着。相形之下，人的寿命充其量才七十年，不过是无限短暂的一段插曲而已。

Megaparsec -1, then the Hubble distance of 5.5 billion seconds gap, that is 18 billion light-years away.

若取H为55KM.D秒－1。兆秒差距－1，则哈勃距离为55亿秒差距，即180亿光年。

In the past, astronomers have argued that the hubble constant is between 40 and 90 kilometers per second per megaparsec (one megaparsec is 3.26 million light years).

在过去，天文学家认为哈勃常数在每百万秒差距每秒40到90千米之间(一百万秒差距为三百二十六万光年)。

For many years, right up until the launch of the Hubble telescope - the range of measured values for the expansion rate was from 50 to 100 kilometers per second per megaparsec (a megaparsec, or mpc, is 3.26million light-years).

但直到哈勃望远镜发射前，哈勃常数的值还在每百万秒差距50~100km/s这么大范围内（百万秒差距缩写为mpc，相当于326万光年）。

The cluster lies 2600 light-years from Earth in the constellation of Monoceros.

这棵"树"实际是距离地球2600光年的麒麟星座。

Explanation: At the edge of a large molecular cloud in Monoceros, some 3,000 light years away, dark filaments of dust are silhouetted by luminous hydrogen gas.

说明：在麒麟座有一块巨大的分子云，离我们约3，000xx光年，在它的边缘处，黑暗的尘埃纤维遮住发光的氢气发出的光，形成黑色的剪影。

This star-forming nebula, which lies 5,000 light-years away in the constellation Monoceros, is named for its rosebud-like shape when seen using only optical light.

这个星构成星云，它离开麒麟星座是5000光年，它被命名为：蔷薇花蕾――的外形，观测它只要用眼睛的视力。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
