物质在加热或冷却过程中可发生一定的物理和化学变化,研究测定这种变化的技术即为热分析技术。广义地说,测定物质的熔点、凝固点、沸点等也是一种热分析,因此,它的历史可追溯到很远。二十世纪以来,对于物质经受温度所引起的物理和化学变化,特别是能量的变化进行了深入的研究。由于矿物、冶金、硅酸盐工业的发展,尤其是近代高 Materials in the heating or cooling process can occur some of the physical and chemical changes, research to determine this change is the thermal analysis technology. Broadly speaking, the melting point, freezing point, boiling point, etc., of the test substance are also a form of thermal analysis and, as such, its history goes back a long way. Since the twentieth century, the physical and chemical changes caused by the material to withstand the temperature, especially the energy changes, have been deeply studied. Due to the development of minerals, metallurgy and silicate industries, especially in modern times
