摘　　要：以卤化银光色玻璃在发生光色过程中X- 的电子逸出几率a和Ag+ 的电子俘获几率p为基础 ,推导了卤化银光色玻璃的光致变色动力学模型。比较了F系列卤化银光色玻璃的理论计算的变色动力学曲线与实测的变色动力学曲线 ,并讨论了光致变色的速度与辐照时间的关系 ,最后探讨了饱和变暗透过率与 5min变暗透过率的差异 .The darkening kinetics model of photochromic glass_containing silver halide was deduced on the basis of electron transgression probability and electron capturing probability, and its mathematics solution was given. Then, the calculated darkening kinetics curves and the measured darkening kinetics curves of F_series photochromic glasses containing silver halide were compared. The relationship between darkening speed and darkening time was discussed. At last, the saturated dardening transmittance was calculated and its difference with the five minutes darkening transmittance was studied.
