以ＡｇＸ光色玻璃中的胶体Ａｇ０转化为Ａｇ＋的转化几率ｂ为基础，推导了ＡｇＸ光色玻璃的退色动力学模型：Ｔ＝１—Ｂ—ｋＣ０exp（－ｂｔ），并结合实测的退色动力学参数给出了这一模型的数学解法，并将根据该理论模型绘制的退色动力学曲线与实测的退色动力学曲线进行了对比．结果表明：根据ＡｇＸ光色玻璃中的转化几率ｂ所推导出的退色动力学模型，较好地解释了ＡｇＸ光色玻璃的退色过程，转化几率ｂ较准确地表征了退包动力学的退色速度，理论计算的退色动力学曲线与实测的退色动力学曲线完全吻合．这进一步证明了本文提出的退色动力学模型及其所依赖的理论基础的正确性．
A fading kinetics model，T=1-B-kC0exp(-bt), was deduced on the basis of transition probability, b, of silver colloid forming silver ion, the
solutions of the model were given by applying the measured fading kinetics parameters with a computer, and the measured fading kinetics curves and the
calculated fading kinetics curves of F-series photochromic glass containing AgX were compared. The results indicate that the fading kinetics model
preferably explains the fading process of the photochromic glass, and the transition probability, b, accurately expresses fading rate of fading kinetics. The calculated curves and measured curves of fading kinetics of F-series
photochromic glasses containing AgX are almost similar. So these results further prove that the fading kinetics model is effective to explain the
fading process, and the theory as the basis of the fading model is correct.
