摘　　要：利用Cowan程序首次计算了Ar原子价壳层跃迁3p→4s和3p→3d中4个电偶极跃迁的广义振子强度。并把计算结果与实验结果进行了比较。4个电偶极跃迁的广义振子强度计算结果在峰形上与实验结果符合较好,绝对值在小K2区间与实验结果也基本相同,只是在大K2区间与实验结果存在微小差别。而跃迁3p→4s中2个电偶极跃迁总的广义振子强度的计算结果实验结果相比较也是在峰形上符合较好,在绝对值上存在差别。The generalized oscillator strengths（GOS＇s） for four electric-dipole transitions in 3p→4s and 3p→3d of the atoms Ar are calculated using the Cowan program for the fist time.Furthermore,they were compared with the experimental results.The calculated GOS＇s for four electric-dipole transitions are in good agreement with the experimental ones in profiles,and are in agreement with the experimental ones about the absolute values in the lower K2 region,but there are obvious differences about the absolute values in the larger K2 region.Besides,the calculated total GOS for two electric-dipole transitions 3p→4s are in agreement with the experimental ones in profile,but have differences between them in absolute values.
