研究了(45-x)RO的酸结构性质。XNA(2)O.2.5Al(2)O(3)。研究了52.5P(2)O(5)(R-镁、钙、锶、钡、氧小于或等于31mol%的x)玻璃。玻璃摩尔体积的变化与Na+离子取代Mg2+离子后玻璃中端基的形成密切相关，从而导致玻璃密度和折射率的变化。含CaO玻璃的Na2O取代性能主要取决于取代CaO的Na+离子的低场强，尽管玻璃中的端基增加了。含有SrO和BaO的玻璃，其中一些被Na2O取代，其性质的变化可以用Na+离子和碱土离子之间的质量、场强和极化率的差异来解释，这是因为尽管Na2O取代了玻璃的结构，但玻璃的结构发生了很小的变化。
The properties acid structure of (45 - x)RO . xNa(2)O . 2.5Al(2)O(3) . 52.5P(2)O(5) (R - Mg, Ca, Sr, Ba, O less than or equal to x less than or equal to 31 mol%) glasses were investigated. The variation in the molar volumes of glasses in the MgO series is closely related to the formation of the end groups in the glasses with the substitution of Na+ ions for Mg2+ ions, resulting in a variation of the density and refractive index of the glasses. The properties of glasses containing CaO in terms of Na2O substitution depend mainly on the low field strength of Na+ ions substituting for CaO even though the end groups occurring in the glasses increased. The variation in properties of the glasses containing SrO and BaO, some of which were substituted by Na2O, could be explained by differences in masses, field strength and polarizability between the Na+ ions and the alkaline-earth ions due to a small variation in the structure of the glasses despite Na2O substitution.
