摘　　要：本文描述了光热折射光谱分析法,做出了折射信号随功率改变的关系及Cu^(++)的工作曲线,给出了CU^(++)在水溶液中的最低检测限并讨论了探测光束散焦的特性。A new laser spectroscopic analysis method was described, photothermal refraction spectroscopy. The change of photothermal refraction signal with pump beam power was gaven and so was the working curve of Cu ion. The detection limit of Cu ion in water was gaven and the property of defocusing of probe beam was discussed.
