Abstract
Thermal conductivity κ of organic solutions containing m mole Fe(ClO4)26.0H2O and m mole Fe(ClO4)37.1H2O was investigated against m. The dimensionless figure of merit ZT is found to be larger in methanol (MeOH) and acetone solutions than that in aqueous solution. We further found that the corrected thermal conductivity (κcor) of organic solutions linearly decreases with increase in m and interpreted the reduction in terms of the suppression of intermolecular energy transfer.
我们研究了含有 m 摩尔 Fe(ClO4)26.0H2O 和 m 摩尔 Fe(ClO4)37.1H2O 的有机溶液的导热系数 κ 与 m 的关系。发现甲醇（MeOH）和丙酮溶液中的无量纲优度 ZT 比水溶液中的大。我们进一步发现，有机溶液的校正热导率 (κcor)随 m 的增大而线性减小，并从抑制分子间能量传递的角度解释了这种减小。
