| 中文摘要 | Excess heat capacities at glass transition temperature in two types of glass-forming systems of [xNaNO(3)center dot(1-x)KNO3](60)center dot[Ca(NO3)(2)](40) (0 a (c) 1/2 x a (c) 1/2 1) and Ca(NO3)(2)center dot yH(2)O (4a (c) 1/2ya (c) 1/213) are studied. In the former system, with the replacement of K+ cation with Na+ cation, the excess heat capacity is around 65.1 J center dot mol(-1)center dot K-1, while the excess increases by 38.9 J center dot mol(-1)center dot K-1 upon one molar H2O content in latter system. A quantitative description to the excess heat capacity is built up with the thermal effects of atomic and molecular translational motion in liquids. The results might offer a further understanding to the glass transition. |
