摘　　要：利用STA 449 F3型同步热分析仪对邻苯二甲酸二甲酯和邻苯二甲酸二乙酯及其混合溶液的热学性质进行了测量,结果表明:邻苯二甲酸二甲酯在所测温区内出现了玻璃化转变、结晶和熔化过程,而邻苯二甲酸二乙酯仅仅出现了玻璃化转变过程;且邻苯二甲酸二甲酯的玻璃化转变温度高于邻苯二甲酸二乙酯的玻璃化转变温度.混合溶液的玻璃化转变温度随着邻苯二甲酸二甲酯质量分数的增加出现了升高的规律,其结果基本满足线性关系.Solid physics is one of core courses of applied physics. In this article, the beneficial attempts reform during the teaching contents, teaching methods of solid physics are introduced, and all of those reforms are based on the professional training goal of applied physics, practice instance and features of solid physics in Yili Norreal University. Especially, introduce the work of course resource construction and its great promoting effection on solid physics teaching.
