A method to calculate the temperature inner the capillary in the running procedure was firstly proposed in this paper. From the migration time for aesculin, aesculetin and formamide in ideal and non-ideal conditions, the temperature inner the capillary under the influence of 20kV of applied voltage was obtained to be about 35℃.
文章中我们还首次提出了一种根据不同电压下获得的迁移时间数据计算运行过程中毛细管内温度的新方法,在本实验中使用20kV操作电压时,毛细管内温度大约是35℃。

The influence of acidity on fluorescence and absorption spectra were investigated. Using quinine bisulphate as a reference, fluorescence quantum yield of aesculin in the condition of pH=4.96 was determined to be 0.76 at excitation wavelength 335nm, and in pH=9.40 was 0.80 at 375nm.
探讨了酸度与浓度对其荧光和吸光性质的影响,以硫酸奎宁为参比,测得秦皮甲素水溶液的两种强荧光型体的荧光量子产率,在pH=4.96,激发波长335nm条件下,荧光量子产率为0.76;在pH=9.40,激发波长375nm条件下,荧光量子产率为0.80。
