【摘要】 由于射频场谐波的存在 ,致使其二次谐波的共振跃迁与双量子跃迁信号重叠 ,因此观察双量子跃迁 ,必须首先排除射频场二次谐波共振的影响 .本文分析了光磁双共振实验中关于双量子跃迁产生的条件、判断和观测 ,并分析了多频率共振的原因 .更多还原

【Abstract】 Because of the existence of the harmonic wave of radio frequency field,the secondary harmonic resonance transition signal and double quantum transition signal are overlapped. So, in order to study double quantum transition, the effect of harmonic resonance transition signal must be elminated firsly. This paper analysed the factor, criterion, observation for double quantum transition and the cause of multifrequency resonance in optical pumping magnetic resonance experiment.更多还原
