近年来计算相图的研究虽在迅速地发展,但用试验方法绘制依然是获得相图资料的重要手段。由于试验条件苛刻,特别是那些高熔点、不稳定体系,各家绘制的相图出入较大,一些已被公认的相图,如今看来也存在一些问题。根据相图与体系热力学之间的严格关系,可找到判别相图正误的方法,反之也提供了计算体系热力学数据的新途径。 In recent years, although the research of calculating phase diagram has been rapidly developed, it is still an important means to obtain phase diagram data by experimental methods. Due to the harsh test conditions, especially those with high melting point and unstable system, the drawn phase diagrams of each house are quite different from each other. Some well-known phase diagrams now appear to have some problems. According to the strict relationship between the phase diagram and the thermodynamics of the system, the method of judging the correctness of the phase diagram can be found, on the contrary, it also provides a new way to calculate the thermodynamic data of the system.
