通过溶胶凝胶法和超临界二氧化碳干燥法制备了石墨烯气凝胶/硝酸铵（GA/AN）纳米复合含能材料。采用元素分析（EA）、扫描电子显微镜（SEM）、N2吸附测试和X射线衍射（XRD）对GA/AN纳米复合含能材料的形貌和结构进行了表征，用TG和DSC测试了其热分解性能。结果表明，在GA/AN纳米复合含能材料中，AN以纳米尺寸存在于石墨烯气凝胶中，平均粒径为71nm，质量分数为92.71%。石墨烯对AN的热分解具有促进作用，与纯AN相比，GA/AN纳米复合含能材料的热分解温度提前33.68℃，表观分解热增加了532.78J/g。

This paper introduces a system for automatic measurement and control of temperature and moisture by the microcomputer. In the system,MCS-51 single chip computer serves as the intelligent device. It also states the working principles of the system,its hardware structure and software design.
