随着世界环境和能源危机日益严峻,绿色环保型的热电材料受到了人们的高度重视,引起了各国对环保能源替代材料的广泛研究.热电材料具有重量轻、体积小、无污染、无毒、无噪音的优点,成为了相关研究领域里的一个热点.
本文概述了热电材料的定义及发展历史；概述了热电材料的研究开发进展；介绍了热电材料的应用、分类和热电效应；总结了热电材料的性质、性能提高的途径；介绍了热电材料在温差发电和热电制冷方面的应用；并对Ca3Co4O9、Sr的结构和性质进行阐述.
采用化学共沉淀法对Ca3Co4O9掺Sr进行研究,具体步骤为：原料的计算—原料的称量—溶液的配制—陈化—洗涤—烘干—研磨—煅烧—研磨—压片—烧结.最后对Ca3Co4O9掺Sr热电材料进行XRD检测、表面显微形貌分析

As the world's environment and the increasingly serious energy crisis,green environmental protection of the thermoelectric material was attached great importance to by people,has caused the extensive research of environmental protection energy alternative materials.Thermoelectric materials with light weight,small volume,the advantages of non-toxic,no pollution,no noise,has become a hot spot in research field.
再问： 还有后面的嘛？？谢谢
