摘要

许多研究者研究了玻璃在退火范围内和退火范围附近的密度变化。Kanai和Satoh通过引入网络温度的概念和反应模型,提出了一种分析密度随时间变化的理论,但此后观察到的一些特殊现象无法用他们的理论解释,需要进一步推广。本文进行了这一扩展,并证明了Daragan或Ritland所研究的密度现象,或Suetoshi和Hara, Tsurumi所观察到的密度现象,或作者所观察到的密度现象,可以通过引入一些玻璃结构可以占据的能级、它们之间的态跃迁和跃迁概率随温度的变化,并对它们作出适当的假设来相当定量地分析。还推测,冰点的长期变化或玻璃温度计的热后效可以用类似的概念和数学处理来解释。

Analyses of Density Phenomena of Glass by a Reaction Model:Density Change of Glass due to Heating (Part 3)
Density changes of glasses in and near their annealing ranges were studied by many investigators. Kanai and Satoh proposed a theory which analyzed change of density with time by introducing the concept of network temperature and the reaction model, but, hereafter, some particular phenomena were observed which could not be explained by their theory and further extension has been needed.In this paper, this extension is done and it is shown that the density phenomena studied by Daragan or Ritland, or particular ones observed by Suetoshi and Hara, Tsurumi, or by the author, can be analyzed rather quantitatively by introducing some energy levels which can be occupied by glass structures, transitions of states between them and changes of transition probabilities with temperature, and by making suitable assumptions for them.It is also speculated that secular changes of ice point or thermal after-effects of glass thermometers can be explained with similar concepts and mathematical treatments.
