摘　　要：针对有机化学教学中部分互为同分异构体的有机物的熔点的反常现象,本文依据有机物的熔点不仅与熔化焓(□(?)H(?))有关,而且也与其标准摩尔熵(S(?))密切相关。并就部分有机物标准摩尔熵对熔点的影响作了讨论。The abnormal phenomenon that the melting point of each other the isomerism in witch the part of organic matter in the chemistry teaching.The molting point not only with the enthalpy of melt (△_mH_m~θ) relevant, but also is according to the stand molar entropy is closely related.And the stand molar the entropy (S_m~θ) of organic matter are influence towards melting point made of discussion.

关 键 词：标准摩尔熔化焓 标准摩尔熵 熔点
