摘　　要：对光磁共振实验中各反常共振信号对应的射频信号进行了研究,提出了反常共振信号的判断方法.利用傅立叶级数展开,对反常射频信号各谐波分量的强度进行了定量分析.结果表明,反常共振信号是由射频信号中的谐波所引起,而非多量子跃迁的结果.The causes of radio-frequency signals engendering the abnormal resonance signals in optical pumping magnetic resonance experiment are investigated.The method for detecting the abnormal resonance signals is proposed.The harmonic waves of the abnormal radio-frequency signal are quantitatively analyzed using Fourier series expansion.The results suggest that the abnormal resonance signals are originated from the harmonic waves of the radio-frequency signals instead of the multiple-quantum transitions.
