利用已知化合物的生成热,对含有化合物的二元系推导了由相图计算活度的公式,提出了活度计算的新方法。用导出公式计算了Al-Ce、Al-La两个二元系在整个浓度范围内的活度系数,并进行了初步分析。
Using the heat of formation of known compounds, the formula for calculating the activity from the phase diagram was deduced for binary systems containing compounds, and a new method for calculating the activity was proposed. The activity coefficient of Al-Ce and Al-La binary systems in the whole concentration range was calculated by the derivation formula and the preliminary analysis was carried out.
