摘    要：本文提出了在不同已知条件下共晶二元系由相图计算组元活度及体系超额摩尔自由焓的新方法,并对Al-Sn二元系进行了计算,所得结果与实验值吻合得很好.与前人的算法相比,本文给出的方法更为简单、准确且具有普遍适用性.

Abstract: In this paper, a set of new methods have been proposed for calculating activities of components from the phase diagram in a binary eutectic system under different given conditions. As an example,activity calculation was carried out for binary system Al-Sn, and the obtained result is in excellentagreement with the experimental one. Therefore, the proposed methods can be utilized accurately anduniversally.
