The determinations of the absolute magnitude and the kinematicparameters of RR Lyrae stars, their effects on the estimations of thedistances and the ages of the globular clusters, and the comparisonsbetween the results and ones from other indicators of distances arereviewed.
对天琴RR型变星绝对星等与运动学参数的测定及其对确定距离、球状星团年龄估计的影响，并对它们和其他距离指示器求得的结果的比较作了评述。
-
Forexample, the absolute magnitude of RR Lyrae stars determined from thedirect and indirect measurement methods splits into fainter and brightervalues, the distance modulus of Large Magellanic Cloud and theestimate of the ages of Globular Clusters based on the RR Lyrae starsand the other indicators of distances are not fully coincided.
例如由直接和间接测定方法决定的天琴RR型变星的绝对星等分成较暗和较亮两类，由天琴RR型变星和其他距离指示器决定的大麦哲伦云的距离模数和球状星团年龄估计并不完全一致。
-
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。
-
To send messages using a Cepheid, Learned and his colleagues suggest that extraterrestrials might change the star's cycle.
Learned和他的同事们提出要用造父变星来传递信息，外星人可以改变它的周期。
-
This property can be used to reveal the distance to a cepheid's parent galaxy, because the star's period reveals its intrinsic brightness.
这一特性可以用来测算出一造父变星与其源星系之间的距离，因为变星的周期能显示出其内在亮度。
-
Hubble observations of pulsating stars called Cepheid variables in a nearby cosmic mile marker, the galaxy NGC 4258, and in the host galaxies of recent supernovae, directly link these distance indicators.
哈勃望远镜观测了一个近距离的星系NGC 4258中一类被称为造父变星的脉动变星和当前的超新星，直接比对了这些距离指示器。
-
In the beginning of thesis, we present the works on the search of variable stars and light curve analysis.
在论文的前半段，我的工作重心放在建立快速搜寻变星的方法还有变星光度曲线的分析上。
-
Another refinement of our ladder is the fact that we have observed the Cepheids in the near-infrared parts of the electromagnetic spectrum where these variable stars are better distance indicators than at optical wavelengths.
我们这些距离台阶的另一个改进是：我们已经观测了造父变星的近红外波谱，这些变星在红外电磁波段的量天尺性能比可见光波段更好。
-
At this distance some non-variable stars may by chance appear to grow brighter and fainter in the same fashion as Cepheids due to the physical impossibility of perfect measurements of such dim objects.
在这个距离上，由于仪器的物理测量极限，测量不可能在完全理想状态下进行，某些非变星也会显得有时亮有时暗，就如同造父变星的模式似的。
-
Because NGC 4603 is much farther away than the other galaxies studied with Hubble by the Key Project team, 108 million light-years, its stars appear very faint from the Earth, and so accurately measuring their brightness, as is required for distinguishing the characteristic variations of Cepheids, is extremely difficult.
由于它远在1.08亿光年外，远超项目组团队研究的其他星系，故此恒星变得非常黯淡，而任务要求必须正确测定其中的特定变星——造父变星——的光度，显得格外困难。
