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.
这对高聚物是一完全互溶的共混体系，当共混体系处在熔点和相混合温度之间时，同时存在结晶的熔融相和无定形的相容共混相。
When the temperature of the blend is between melting-point and phase-mixing point, both melting-crystal phase and amorphous miscible phase are present.
