摘　　要：本文结合等吸收点激发-校正荧光发射光谱积分面积比相对测定溶液荧光量子产额法的特点和实际测量体会,讨论了相对法测定溶液荧光量子产率的某些影响因素,诸如吸光度A的控制,λ_(ex)的选择和准确度要求,散射和荧光背景影响,以及标准和未知溶液间浓度的配匹问题,并提出了消除或减少这些影响的方法。Some influeucing factors in the relative method for determining relative fluorescencequantum yield of solution, such as absorbance, selection and accuracy of excitation wavelength,scattered light and matching concentration of sample and standard solutions are descussed. Somemeans for reducing or even eliminating these influences are suggested.
