通过热力学分析和数学计算，讨论颗粒呈现面心立方堆积方式时，华东烧结模型中膨胀机制和收缩机制对烧结体总表面能的作用和总孔隙度比变化的影响，计算表明烧结过程中收缩机制占主导地位。
Through thermodynamic analysis and mathematical calculation, the influence of expansion mechanism and shrinkage mechanism on the total surface energy of sintered body and the change of total porosity ratio of East China sintering model are discussed when the particles present face-centered cubic stacking mode. The calculation shows that the shrinkage mechanism Dominant.
