The results are consistent with experimental trends in interatomic distance, linear thermal expansion coefficient and BO4 units. The amount of 5- to 8-membered rings at x = 0.2 is larger than the other composition range. This suggests that the structural unit constructed by a few rings is related to suppression of thermal expansion.}, pages = {113--116}, title = {分子動力学シミュレーションを用いたナトリウムホウ酸塩ガラスにおけるホウ酸異常現象の考察}, volume = {17}, year = {2018}, yomi = {ヤマモト, ユウヤ and サワグチ, ナオヤ and ササキ, マコト} }
