In this paper, the photochromic properties of several AgX photochromic glasses of different compositions are studied, with the help of computer, the mathematical regressive analysis is applied to the darkening curves of the glasses and an empirical darkening curve equation is obtained. It shows that the parameter b tends to increase with the increase of the darkening rate. By virtue of the equation, we can judge the darkening process of glasses at different phase-separated temperatures and measuring temperatures.
