本文从键压缩模型的角度，对一系列多组分二硼酸钠基玻璃的计算体积模量与结构之间的关系进行了理论分析。分析的主要参数是计算得到的弹性模量、平均拉伸力常数和平均原子环尺寸。这些参数是针对每种玻璃系列和每种玻璃成分计算的。结果表明，这些玻璃的平均力常数和弹性模量对二硼酸钠含量的降低很敏感。这种行为归因于摩尔体积的增加，以及不同改性剂的作用。
This manuscript presents a theoretical analysis of the correlation between the computed bulk modulus and the structure of a series of multicomponent sodium diborate based glasses in terms of the bond compression model. The main parameters in the analysis were the computed elastic moduli, the average stretching force constant and the average atomic ring size. These parameters were calculated for every glass series and for every glass composition. The results showed that the average force constant and the elastic moduli of these glasses are sensitive to the decrease in the sodium diborate content. This behaviour was attributed to the increase in the molar volume, and to the role of the dierent modifiers.
