利用第二次世界大战中的无线电技术，射电天文学在战后得以蓬勃发展。1963年，通过证认3 C 射电源表，发现了类星体。类星体在各电磁波段都有辐射，因此有多种方法可以寻找类星体。作者利用无缝光谱方法，找到第一颗中国人的类星体，并首次使用美国的海耳5 m望远镜。

Using the radio technics during the second world war, the radio astronomy was rapidly developed after the war. The first quasar was discovered in 1963 according to the identification of 3C catalog. Quasars emit radio in various wavelengths. We can use different methods to find them out. Using the slitless technic I found the first Chinese quasar. Also I was the first Chinese to use the Hale 5 m telescope.
