Example Sentences:
1.Cepheid variable is the foundation of this ladder
,而造父变星便是这阶梯中不可或缺的其中一环。
2.Cepheid variable stars are stars whose brightness changes at regular periods
造父变星是一种光线按规律周期发生变化的恒星。
3.This makes space telescope invaluable for identifying a rare class of pulsating stars , called cepheid variable stars embedded within m100 ' s spiral arms
这对于从m100的旋臂中分辨出暗藏的造父变星有着莫大价值。
4.One of the key project of hubble s telescope is to gauge as many cepheid variables as possible in more distant galaxies up to 65 millions light years
哈勃太空望远镜的一个重点计划,就是要测量更多更远星系中的造父变星远达
5.Since delta cephei was one of the earliest members of a special kind of variables being discovered , all variables in this family are called cepheid variables or simply cepheids
星的中国名称为造父一,由于它最早被发现的一种新变星类别,所以这类变星皆称为造父变星。
6.Cepheid variables are dimmer than the type i supernova . as a result , the supernova allows us to measure the distances of galaxies further away , but it happens much less often
I型超新星比造父变星光亮,所以能够量度更遥远星系的距离,唯一缺点是不经常有i型超新星爆发。
7.Astronomers made observations of cepheid variable stars [ pictured above ] ? pulsating stars used to measure vast distances ? in the virgo and other clusters to establish the expansion rate and the universe ' s age
天文学家用哈勃观测到仙女星座和其它星群中的造父变星(如图) ,以确定宇宙的膨胀速度和宇宙的年龄。
8.The longer the period , the brighter the star is . thus , by measuring the period of a cepheid variable , we know its absolute magnitude , hence , we can tell how far it is away by comparing with its apparent magnitude
所以,只要知道某一造父变星的周期,我们便可得知它的绝对星等,只要和它的视星等作比较,便可以求得它和我们的距离。
9.We have to use some other methods to measure the luminosity or equivalently the absolute magnitude of the cepheid variable . since we can readily measure the apparent magnitude of a cepheid variable , to measure the luminosity means measuring the distance . we use some distance measurement methods , for example , parallax , to determine the relation
要弄清这个关系,我们要知道不同造父变星的光度和光变周期数据,量度光变周期当然不是问题,但要得知一颗恒星的光度,我们首先要得知它的距离,这时便须借助好像视差法等其他量度天体距离的方法。
10.Except those celestial objects of several hundred light years , astronomers rely primarily on cepheid variables for measuring distances of celestial objects . using ground telescopes to gauge cepheid variables enable us to directly measure celestial objects within 20 to 30 millions light years . for more distant stars , other methods have to be used
除了几百光年内的星体外,天文学家很主要倚靠测量造父变星来计算天体的距离,利用地面望远镜测量造父变星,可直接给出约二三千万光年内星体的距离,而对于更遥远的星体,天文学家便要借助其他方法,但这些方法还是需要利用造父变星来作校正。
