摘　　要：利用顶杆法膨胀仪，探讨了材料结构、密度与热膨胀的关系，用其它实验方法交叉结合对材料的相变进行了研究，并通过热膨胀曲线确定某些材料的特定工艺参数，实验证实了热膨胀在材料热学性能研究领域中是一种非常简捷、可靠。The relationship between the structure and the density of the composite material and thermal expansion characteristic was explored by push rod dilatometer. The phase transition of the material was also studied by combined dilatometer with other method. The technological parameters of the glass processing can be determined from the curve of thermal expansion coefficient. Therefore the push rod dilatometer is very useful in the research of thermal performance of the material.
