摘　　要：应用Bien等人计算星表系统差的方法，计算了GC和SAOC星表相对于FKS星表的系统差。计算结果与GC经FK4星表作中间星表所得的结果作了比校；两者比较的结果表明只要有较多的共同星，两种方法获得的结果基本一致。并且将SAOC星表和AGK3，Perth70星表的系统差也进行比较，除近天极附近的区域外，所得结果一般都符合得较好。With the calculation method of Bien et al. describing systematic differences, the systematic differences of the GC and SAOC catalogues relating to the FK5 catalogue were calculated. The results were compared with that of the GC through the FK4 catalogue as a reference - catalogue. lt shows if there are more common stars, the results of two methods are coincidence in the main. The systematic differences of SAOC and those of AGK3 and Perth7O were also compared, it shows the results are consistent except in the range near the celestial pole.
