摘　　要：本文由云南天文台的光电等高星表(YUA)[1],La Palma子午星表CAMC5[2],以及中国光电等高第三总星表(GCA)[3],东京天文台子午星表(PMC85)[4]相对于FK5系统差的分析。得到以下结果:FK5星表的赤经系统相对比赤纬系统平稳;在赤纬δ=+40°附近由两个子午星表反映出约±0.”1、方向相反的系统差波动,这可能是由观测误差而引起,而不是FK5本身的系统误差。In this paper, according to the analyses of the systematic errors between the astrolabe catalogue of Yunnan Observatory (YUA), La Palma meridian catalogue CAMA6, the third general astrolabe catalogue of China (GCA), Tokyo meridian catalogue PMC85 and the FK5, the results can be summrized as follows, in the FK5 the fluctuations of the right ascension system are smaller than those of the declination system; in the declination system of FK5, there are the opposite fluctuations Δδ3 which reach about ±0'.1 near δ= ±40° in. these two meridian catalogues, this implies probably the observational errors exist in these meridian catalogue's.
