摘　　要：用扩展的Miedema合金元胞模型研究了非过渡金属二元系液相分层规律。结果表明：大，小的二元合金系液相分层．在△Z（价电子数差）与，张成的三维空间中。An extended Miedema's cellular model of alloy systems has been applied to study the regularities of binary monotectic systems consisting of non-transition metals. It has been found that larger and smaller enhance liquid--liquid immiscibility. In the three-dimensional space spanned by atomic parameters, and △Z the representative points of the non-monotectic and monotectic systems with and without solid intermetallic compounds distributed in different regions separately. The criteria of the occurrence of two layer region can be obtained by artificial neural network trained by known data of phase diagrams.
