摘　　要：本文从理论上比较了Rb^(37)和Cs^(133)激射器。结果表明:Rb^(37)激射器具有较大的振荡功率,其原因是Rb^(37)的核自旋量子数小,因而振荡参数阈值比Cs^(133)的大,即Rb^(37)激射器能在较低的原子密度或较低的腔ηQ_c值下维持振荡。A theoretical comparison between Rb^(87) and Cs^(133) masers is undertaken. We findout that Rb^87 maser exhibts larger oscillation power than Cs^(133) maser does. It isbecause the nuclear spin of Rb^(87) is smaller than that of Cs^(133), so the threshold va-lue of oscillation parameter of Rb^(87) maser is larger than that of Cs^(133) maser, i.e,Rb(87) maser can obtain self--sustained oscillations at relatively low atomic densityor small ηQc value.
