只要恰当地控制粒子束的照射时间，该恒星将有效地成为一台调频电台——以“造父变星”的脉冲为基础载波向宇宙广播。
Time the beam right and the star could be turned, in effect, into an FM transmitter-broadcasting to the universe on the underlying carrier-wave of the Cepheid's pulsation.
且由于在另一个星系中的单颗“造父变星”的亮度就足于使其被观测到，所以它们是测算类似星系距离的首选工具。
And, since individual Cepheids are bright enough to be seen in other galaxies, they were the first tool used to estimate the distances to such galaxies.
另一种标准烛光是一种叫做造父变星的恒星。
Another type of standard candle is a type of star called a Cepheid variable.
造父是种特殊的恒星，它能以可以预测的方式周期脉动，就像I型超新星，他们被当做是一样的，不管他们在那里。
Cepheids are a special type of star that pulsates in a predictable way, and like the type 1a supernova, they are assumed to be the same, no matter where they are located.
他们发现了差不多800个造父变星，一种用于准确测量距离的特殊变星。
They discovered almost 800 Cepheid variable stars, a special class of pulsating star used for accurate distance measurement.
哈勃太空望远镜(HST)拍摄的壮丽的漩涡星系ngc 4603，现今发现一类特殊的变星——造父变星的最远的星系。
NASA Hubble Space Telescope (HST) view of the magnificent spiral galaxy NGC 4603, the most distant galaxy in which a special class of pulsating stars called Cepheid variables have been found.
他的首次重大发现产生于他认识了一颗造父变星的时候。
His first great discovery was made when he recognized a Cepheid variable star.
本图是其中一个星系：漩涡星系ngc 4603，本报告中发现造父变星的最远星系。
It is the spiral galaxy NGC 4603, the most distant galaxy in which Cepheid variables have been found.
造父跟泰豆学习驾车。三年间，泰豆从未告诉他一句有关驾车方法的话，但造父对师父却更加恭敬。
Zao Fu been learning to drive from Tai Dou for three years, but Tai Dou did not tell him anything about driving, which only added to his respect for his teacher.
造父变星是可靠的宇宙距离(测量)里程碑，其完整的一个光变周期直接反映了星体的本质光亮度。
Cepheids are reliable cosmic distance mileposts. The interval it takes for the Cepheid to complete one pulsation is a direct indication of the stars'; s intrinsic brightness.
在造父变星的一个光变周期内，恒星外层的电离气体是相对不透明的，因此会吸收恒星的辐射而升温，并开始向外膨胀。
At the dimmest part of a Cepheid's cycle, the ionized gas in the outer layers of the star is opaque, and so is heated by the star's radiation, and due to the increased temperature, begins to expand.
