摘　　要：本文描述了一个倾斜交叉、差分式激光热透镜光谱法。采用本方法可消除较高的溶剂空白的影响。文章讨论了调制频率和泵浦光功率对热透镜信号的影响,给出了检测Cu^(2+)的工作曲线,讨论了影响方法灵敏度的诸因素,提出了可能的改进方案。This paper described an obliquely crossed and differential thermal lens(TL) spectrometry, the device can eliminate high solvent effect. The effects of chopping frequency and pump beam power on the TL signal were discussed. The working curve of copper ion was given. Some factors affecting sensitivity were discussed, and possible improvement schemes were given.
