差示扫描量热法（DSC）测量用于研究TeySe（1−y）玻璃体系中的结晶结构弛豫。所检查的组合物为y=0.1、0.2和0.3。从每种研究的玻璃的曲线拟合程序获得单组工具-纳拉亚纳斯瓦米-莫伊尼汉参数。与我们以前的测量a-Se进行了比较，并讨论了特定的TNM参数的发展与Te含量的增加在分子结构的材料的变化。通过几种独立的非拟合方法进一步验证了曲线拟合的结果。
Differential scanning calorimetry (DSC) measurements were used to study enthalpic structural relaxation in the TeySe(1−y)glassy system. The examined compositions were y=0.1, 0.2 and 0.3. Single set of Tool–Narayanaswamy–Moynihan parameters was obtained from the curve-fitting procedure for each studied glass. A comparison with our previous measurements on a-Se was made and the development of particular TNM parameters with increasing Te content was discussed in terms of changes in molecular structure of the material. The curve-fitting results were further verified by several independent non-fitting methods.
