摘　　要：以AgS无机光致变色玻璃为研究对象,测试了其在不同辐照度和照射时间下的透射比、反射比。结果表明,随着照射时间变长,变色玻璃的可见光透射比逐渐增大并趋于稳定,而辐照度对相关参数无影响。计算了该光致变色玻璃在不同照射时间下的遮蔽系数,拟合了两者之间的经验公式。光致变色玻璃的遮蔽系数最大降低幅度可达11.3%,随着照射时间变长逐渐增大并趋于稳定,但始终小于照射前的遮蔽系数。Tests and compares the transmittance and the reflectance of the AgS inorganic photochromic glass under different irradiance and irradiation time.The results show that the inorganic photochromic glass'visible transmittance increases to a stable value with the irradiation time growth,while there is no significant correlation between irradiance and related parameters.Calculates the shading coefficient of the inorganic photochromic glass under different irradiation time,and fits an empirical formula between irradiation time and shading coefficient.The maximum reduction of the shading coefficient can reach 11.3%,with the increase of irradiation time,it gradually increases and tends to be stable,but it is always less than the shading coefficient before irradiation.
