(1)Development of a simplified spectroscopic method using the spectrum conversion analysis of digital imageBy comparing the three different methods of spectrum conversion of digital images which have been proposed in the field of computer graphics, it was investigated a possible method of simulating the visible spectrum from RGB values of digital image. It was found that s simple method of summing up several standard spectrums by considering the values of RGB indicates a good performance for simulating visible spectrum. A computer program of spectrum simulation using the RGB values was developed using the spectrum conversion method.(2)Application of the simplified visible spectroscopy for the chemical experimentsThe simulation methods of the visible spectrum developed in the present study was applied as a simplified visible spectroscopic method to several chemical experiments such as determination of acid dissociation constants for several pigments of acid-base indicator, kinetic analysis of the decomposition of hydrogen peroxide, quantitative analysis of the benzenesulfonic acid, and so on. The usefulness of the simplified visible spectroscopy at the students' laboratory was confirmed by the practical application of these chemical experiments to students' laboratory at colleges and high schools. By applying the method for the digital video images of BZ reaction, it was indicated that the present method can be applied as a simplified time-resolved visible spectroscopy. Alternative applications of the present method as a simplified microscopic visible spectroscopy and fluorescence spectroscopy were also examined.

（1）利用数字图像的光谱转换分析，提出了一种简化的光谱分析方法。通过对计算机图形学领域中提出的三种不同的数字图像光谱转换方法的比较，研究了一种利用数字图像的RGB值模拟可见光谱的可能方法。结果表明，考虑RGB值的几个标准光谱相加的简单方法对模拟可见光谱具有良好的性能。利用光谱转换法，编制了一个利用RGB值进行光谱模拟的计算机程序。（2）简化可见光谱法在化学实验中的应用本研究建立的可见光谱模拟方法作为一种简化的可见光谱法，应用于几个化学实验，如酸碱指示剂中几种颜料的酸离解常数的测定，过氧化氢分解的动力学分析，苯磺酸的定量分析，通过这些化学实验在大、中学学生实验室中的实际应用，证实了简化可见光谱法在学生实验室中的实用性。将该方法应用于BZ反应的数字视频图像，表明该方法可以作为一种简化的时间分辨可见光谱法应用。本方法的替代应用作为一个简化的显微可见光谱和荧光光谱也进行了检查。
