用差热分析法鉴别相变类型

The Identification of Phase Transition Types by Differential Thermal Analysis

相变类型的鉴别是困难而复杂的,一般采用X射线单晶四环衍射法。这种方法仪器昂贵,分析复杂。提出用差热分析鉴别相变类型,既简单,又准确可靠。

The identification of phase transition types in single-crystals is difficult and complex. The researchers usually adopt the four arc X-ray diffraction method for this purpose. But this method is expensive in apparatus used and difficult in analysis. This paper presents a simple ,accurate and reliable method which uses differential thermal analysis to identify the phase transiton types in crystals.
