本文根据层片状共晶生长理论，利用时间相关模型对存在对流作用的Al-CuAl2共晶层片间距进行数值求解最小和最大层片间距（λo和λmax）的计算结果与实验结果符合较好，熔体的流动使Al-CuAl2共晶稳态生长的层片间距增加；当层片间距超过λmax时，层片组织处于非稳态：共晶生长速率越低，液相流动的影响越大
According to the theory of lamellar eutectic growth, the calculated results of the minimum and maximum interlamellar spacing (λo and λmax) of Al-CuAl2 eutectic layer with convection are in good agreement with the experimental results by using the time-dependent model , The flow of melt increases the interlamellar spacing of eutectic Al-CuAl2 eutectic growth. When the interlamellar spacing exceeds λmax, the lamellar structure is in an unstable state: the lower the eutectic growth rate, the greater the effect of liquid phase flow
