查询词典 megaparsec

The results agree closely with an earlier measurement gleaned from Hubble of 72 ± 8 km/sec/megaparsec, but are now more than twice as precise.

此数据与此前哈勃数据测定的（72±8）km/s/Mpc相当一致，但现在的精度提高了一倍。

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）。

Graf, without question, is the greatest women's player in history.

格拉芙，现在，毫无疑问是女子网坛历史上最伟大的选手。

If not, you will have to look around at all your important data.
