摘要
研究了不同浓度的表面活性剂和水溶性高分子在水相或有机相中对激光热透镜信号的增强作用,探讨了其增强机理,表明随表面活性剂、水溶性高分子浓度的变化,溶剂介质微环境物理特性参数发生变化,从而引起热透镜信号的增强.
Enhancement effect of surfactants and polymers on the thermal lens signals was studied. With the change of concentrations of surfactants and polymers, the thermal physical characteristics of the solvent changed, and thus enhanced the thermal lens signals. UK mechanism of enhancement was also studied.
