摘　　要：我们对北京天文台密云２３２ＭＨｚ星表和６Ｃ星表进行了系统的比较和研究，以期对密云星表的完备性和均匀性有一个定量的概念。A meter-wave survey of the sky region north of declination+30°has been carried out with the Miyun Synthesis Radio Telescope(MSRT) at 232 MHz.It is a moderately deep meter-wave survey,working at a frequency intermediate between the 6C(151 MHz) and B2/B3(408 MHz) catalogues among the tens of radio sky surveys.Its resolution is nearly the same as theirs,and the MSRT sky region surveyed is almost the same as that of 6C,while B2/B3 covers a much smaller region.In this paper,we present a brief statistical comparison between the Miyun 232MHz Catalogue and the 6C Catalogue in order to get some quantitative understanding of the completeness and uniformity of the former.
