| 1. | Radio astronomy today is armed with the largest antennas in the world .
射电天文学拥有世界上最大的天线。 |
| 2. | Radio astronomers are now able to synthesize the response of a partially filled aperture of large diameter and thus to map variations in nebular brightness .
射电天文学家现在已经能够把部分充满的大直径孔径进行综合，从而描绘出星云亮度变化图。 |
| 3. | We are used to calling an instrument of this kind in optics a telescope, and the radioastronomical counterparts are therefore briefly named "radio telescope" .
在光学上我们通常称这种类型的仪器叫望远镜，因而射电天文学上的对应物简称为“射电望远镜”。 |
| 4. | Foremost among the techniques used to study dense interstellar region is molecular radio astronomy, a relatively new and rapidly developing interdisciplinary science .
在用来研究高密星际区域的技术中，最重要的是分子射电天文学；这是一门较新的发展迅速的边缘科学。 |
| 5. | Sub - arcsec radio astronomy
亚角秒射电天文学 |
| 6. | The technique has been highly successful in radio astronomy , and in both satellite and aircraft borne radar
该技术在射电天文学、卫星雷达和机载雷达上均获得了巨大成功。 |
| 7. | Why can radio astronomers observe during the day , whereas optical astronomers are ( for the most part ) limited to nighttime observing
译文:为什么射电天文学家可以在白天观测,而光学天文学家的绝大多数观测只能在夜晚进行 |
| 8. | We are used to calling an instrument of this kind in optics a telescope , and the radioastronomical counterparts are therefore briefly named " radio telescope "
在光学上我们通常称这种类型的仪器叫望远镜，因而射电天文学上的对应物简称为“射电望远镜” 。 |
| 9. | In china , the chinese academy of sciences is supporting a new project called " pre - research on five hundred meter aperture spherical telescope fast
现时中国科学院在射电天文学这范畴中正重点支持一个名为500米口径射电望远镜预研的项目，这望远镜的英文简称为fast five hundred meter aperture spherical telescope |
| 10. | In modern radio astronomy , these radio celestial bodies are called " discrete sources ? cassiopeia a , cygnus a and taurus a are some examples of discrete sources . the letter " a " represents a strong radio source
在现代的射电天文学中，这些射电天体称作分立射电源，例如仙后座a ，天鹅座a和金牛座a等， a是代表强的射电源。 |
