摘　　要：通过建立泡孔生长的数学模型,求解聚合物/超临界流体发泡体系的控制方程,得到泡孔生长的规律及影响因素。以聚丙烯/超临界CO2发泡体系为例,通过调整温度、系统压力、扩散系数等参数,得到不同条件下聚丙烯/超临界CO2体系的泡孔生长情况,并分析了各参数对泡孔生长的影响。Based on the establishment of a mathematical model for cell growth, solving equations of polymer/supercritical fluid foam system were solved,the rules and influence factors of the cell growth were also analyzed. For PP/supercritical CO2 foam system as an example, by adjusting the temperature, pressure systems and diffusion coefficient parameters, information of PP/supercritical CO2 system under different conditions was got,and various parameters＇ effects on the cell growth was analyzed.
