用动态光散射法测量了磷酸盐玻璃成型熔体在50~40摩尔%P_2O_5范围内的结构松弛，其中PO4四面体的类聚合物长链被系统地缩短。研究结果揭示了弛豫的非指数性以及玻璃脆性的成分变化，后者在钠和锌之间显示出异常的差异。
Dynamic light scattering was performed to measure the structural relaxation in sodium and zinc phosphate glassforming melts in the range from 50 mol% to 40 mol% P2O5 where long polymer-like chains of PO4 tetrahedra are systematically shortened in length. The findings reveal compositional changes in the non-exponentiality of the relaxation as well as in the glass fragility, the latter of which exhibits anomalous differences between sodium and zinc.
