铅锡合金的准二维电沉积物具有伪共晶-固溶体双层结构。
A two-layered structure of eutectic-solid sulotion is formed in the microstructure of Pb-Sn alloy obtained from quasi-two-dimensional electrodeposition.
分析结果表明，共晶结晶时硅之所以成为先析出相，铝硅合金之所以存在伪共晶，都有其热力学原因。
The results of analysis show that wty the silicon separatas out as a preliminary phase, and why the Al-Si alloys have their own pseudoeutectic structures are all for thermodynamical reasons.
