双语例句
- 1. For 100 years astronomers have paid particular attention to a class of variable star known as the Cepheids.
- 过去100年来，天文学家特别注意一类称作“仙王座变光星”的恒星。
youdao
- 2. 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.
- 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。
youdao
- 3. 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.
- 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。
youdao
- 4. 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.
- 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。
youdao
- 5. With Hubble's powerful capabilities, the team was able to side step some of the shakiest rungs along the previous distance ladder involving uncertainties in the behavior of Cepheids.
- 有了哈勃望远镜的强大能力，团队就能直接跨过某些不稳定的台阶：（由于清晰度不够，）先前对这些造父变星行为的观测不是很准确。
