摘    要：本文用电子计算机根据准规则溶液(quasi—regular solution)模型近似,计算了Ga—As—Ge三元系在800,900,1000,1100和1200℃的初晶为GaAs的液相等温线。计算结果和文献中实验测定值符合良好,它比前人报导的规则溶液(regular solution)模型计算值更为符合实验值,这对高温时尤为明显。

Abstract: Liquidus isotherms at temperatures 800,900,1000,1100 and 1200℃in the GaAs primary phase field of the ternary condensed phase diagramof the Ga-As-Ge system are calculated by electronic computer according toa quasi-regular solution approximation,The result of calculation is in goodagreement with the experimental data reported in literature,and it is closerto the experimental data than the calculation reported before by the use ofa regular solution model,especially at the higher temperatures.
