【摘要】 通过对五水硫代硫酸钠（Na₂S₂O₃ 5H₂O）非等温脱水过程的热力学数据进行理论求算和分析,结合两种热分析实验结果,包括差热/热重联机（DTA/TGA）和差示扫描量热（DSC）,实验测定结果与理论求算相互验证,确定了五水硫代硫酸钠脱水过程的类型。研究的理论和实验结果表明,Na₂S₂O₃ 5H₂O的脱水过程是先脱出液态水并形成水溶液,然后随着温度的升高,溶液中水的再气化。更多还原

【Abstract】 Inorganic phase materials such as Na₂S₂O₃ 5H₂O for thermal energy storage are typically salt. The thermodynamics data was calculated and analyzed to judge dehydration process of Na₂S₂O₃ 5H₂O. The actual process was determined by DTA/TGA and DSC. The results shows that theory conform to practice. The dehydration of Na₂S₂O₃ 5H₂O firstly come into being aqueous solution., then H₂O divorced from aqueous solution to change in gas.更多还原
