The new technique reduced the distance ladder to three "rungs":(1) The distance to galaxy NGC4258 is measured using straightforward geometry and Kepler's laws;(2)Cepheids in six more distant galaxies are used to calibrate the luminosity of Type Ia supernovae;(3) The Hubble constant is measured by observing a brighter milepost marker, Type Ia supernovae, in more distant galaxies hundreds of millions of light-years away, embedded in the expanding universe.

这种新技巧简化了距离跳跃为三个"阶梯"：1、星系NGC 4258的距离采用开普勒定律和简单直接的几何方法精确测量；2、在6个更远的星系中的造父变星用来校准Ia超新星的光度；3、深嵌于数亿光年外的膨胀宇宙中的星系中的Ia超新星——一种遥远而明亮的量天尺，被用于精确测定哈勃常数。

After correcting an initial problem with the lens, when the Hubble Space Telescope was first launched in 1990, the floating astr bservatory began to relay back to Earth, incredible snapshots of the 'final frontier' it was perusing.

哈勃太空望远镜是1990年发射到太空的。在修正了最初的镜片的问题后，这架悬浮太空望远镜开始向地面发出照片。

NASA's next shuttle mission, a long-delayed repair effort at the Hubble Space Telescope , is scheduled for May.

NASA 的下个太空任务是长久以来一直未能解决的哈勃望远镜的修理问题，这是在五月就计划过的事情。

She explained that the details seen in the Hubble view show a lumpiness to the debris

她解释说哈勃照片中凹凸不平的碎片羽状物是由木星大气的不稳定气流引起的。

The details seen in the Hubble view shows lumpiness in thedebris plume caused by turbulence in Jupiter's atmosphere.

这次的痕迹很像当年彗星撞击后的撞击特征，哈勃图像的精细细节显示出撞击后在木星大气涡流中的羽毛状残骸团块。

She explained that thedetails seen in the Hubble view shows a lumpiness to the debris plumecaused by turbulence in Jupiter's atmosphere.

西蒙。米勒补充道。她解释说哈勃图像的精细细节显示出撞击后在木星大气涡流中的羽毛状残骸团块。

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）。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
