摘　　要：在光泵磁共振实验中观测到单量子跃迁共振信号幅度随射频场振幅增加而迅速增加,并很快达到饱和,然后单调缓慢下降的关系.当射频场振幅更大时(约大于3.5V),观测到双量子跃迁共振信号,信号幅度与射频场振幅成二次函数关系.本文对实验结果进行了分析和解释.In the experiment of opto-magnetic resonance, it is observed that single quantum transition resonance signal magnitude rapidly increases and goes to saturation, then slowly goes down with increase of rf field amplitude. Double quantum transition resonance signal is observed when rf field amplitude is more than 3.5 V. Relationship of signal magnitude and rf field amplitude is a squared function. Experimental results are analyzed.
