秒差距

Imagine this. Just one (1) kiloparsec is approximately 31 Trillion kilometers.

考量下这个，一( 1 )千秒差距大约是31万亿公里。

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）。

Given that a parsec is a unit of measurement and not of time, it hardly seemed like a speed record.

考虑到秒差距是个距离单位而不是时间单位，索罗说的可不像是一个速度纪录。

Dimensions: This image is roughly 61 arcseconds (1.5 light-years or 0.47 parsec) wide.

图像尺寸：61角秒，或者说是1.5光年、0.47秒差距。

Theycan travel at tens or possibly even hundreds of kilometers per second,and in the case of young stars extend over a parsec in length.

它们的速度可从10km/s直到数百km/s，而来自年轻恒星的偶极外向流能延伸到1秒差距外。

One parsec is defined as the distance at which a star would show a parallax displacement of 1 second of arc, a distance which proves to be approximately 3.258 light years.

一秒差距被定义为一颗恒星位移一度的距离，此距离经证实大约为3.258光年。

A harsh rocky world less than a parsec away from Tatooine, Geonosis is a ringed planet beyond the borders of the Galactic Republic.

在距离塔图因不到一个秒差距（译者注：1秒差距=3.26光年）的地方有一个叫吉奥诺西斯的星球，这是一个位于银河共和国国界外一个带着光环的行星。

A unit of astronomical length based on the distance from Earth at which stellar parallax is one second of arc and equal to 3.258 light-years, 3.08'×03 kilometers, or .98 × 0 3 miles.

秒差距：天文学自地球起的距离单位，星视差为角秒，等于3.258光年，3.08'×03公里，或。98×0 3英里

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。
