【摘要】 本工作研究了R₂O（RO）-B₂O₃-Al₂O₃-SiO₂系玻璃基础组成与光色行为间的关系。研究结果表明:（1）提出玻璃结构因子[ψ]（满足0<[ψ]<1）作为基础玻璃光色性的必要条件和充分条件的半定量判别式。当0<[ψ]≤0.5时,玻璃光色性呈现良好的规律性。（2）玻璃T_D值温度系数f（T_D）与[ψ]有关。当[ψ]=0.28～0.35时,玻璃f（T_D）为最低值。（3）在恒定[ψ]和R₂O/B₂O₃时,玻璃的T_D,f（T_D）值随R₂O中α（Li/K）增加而呈线性下降。更多还原

【Abstract】 The relationship between the basic composition of glass and its photochromic proper- ties has been studied for the AgX containing glasses in R₂O（RO）-B₂O₃-Al₂O₃-SiO₂ sys- tem. The results show that: （1） A structural factor [ψ] proposed in the range of 0<[ψ]<1 can be used as a semi-quantitative parameter for indicating the photochromic property of basic glasses. For example, when 0<[ψ]<0.5, the glasses exhibit excellent photochromic behavior with regularity.（2）Temperature coefficientf（T_D） of T_Dvalue is closely related to the [ψ] value. For instance, when [ψ]=0.28～0.35, f（T_D） value becomes a minimum.（3） Let [ψ] value and R₂O/B₂O₃ ratio be constant, then f（T_D） value will decrease linearly with increasing α（Li/K） ratio.更多还原
