2. Another type of standard candle is a type of star called a Cepheid variable.: 另一种标准烛光是一种叫做造父变星的恒星。

3. His first great discovery was made when he recognized a Cepheid variable star.: 他的首次重大发现产生于他认识了一颗造父变星的时候。

4. It is the spiral galaxy NGC 4603, the most distant galaxy in which Cepheid variables have been found.: 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。

5. Dr Learned, however, reckons the pulse-period of a Cepheid could be modulated by a suitable beam of neutrinos.: 而且，伦德博士测算出“造父变星”的脉动周期能够用适当的微中子束加以调整。

6. They discovered almost 800 Cepheid variable stars, a special class of pulsating star used for accurate distance measurement.: 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。

7. Admittedly, the energy needed to produce a Cepheid-modulating neutrino beam really would be a sizeable fraction of the output of the sun.: 应当承认，制造用来调整“造父变星”的中微子束所需要的能量确实将相当于太阳整体输出能量的大部分份额。
