摘要：

A sandwich quartz cell is designed and a flow system is set up for photoacoustic calorimentry measurements in the case of optically thick solutions, Merquards non-linear least square is modified to fit the experimental time resolved waveforms. The quenching of benzophenone triplet state by diones is observed using the apparatus and the results arc in agreement with K. Peters' values.
