| 摘 要： | 为了研究淀粉自由基的变化规律,以生物光子辐射理论为基础.根据化学发光的动力学模型,建立了淀粉自由基的发光动力学方程,并根据自由基发光强度与自由基浓度的关系,通过分析得到了淀粉自由基的湮没方程,得到了光强随时间的变化函数.通过拟合发现,函数在不同温度下随时间的变化曲线与实验曲线的相关系数都在0.98以上,能很精确地刻画自由基的弛豫发光规律.

| Abstract: | In order to study the changing law of the starch free radicals, the luminescence dynamics equation about the starch free radicals was set up based on the theory of biophotonics and the dynamics model of chemiluminescence. According to the relationship between luminous intensity and density of the free radicals, the annihilation function of the starch free radicals is obtained. By fitting the luminescence curve at different temperatures, the relative coefficient about the function is fund to be all above 0.98, which can describe the relaxation law about the free radicals accurately. |
