| 摘 要： | 依据华东烧结模型中膨胀机制和收缩机制的数学表征,讨论了两种机制的相互关系.结果表明烧结初期,膨胀机制占主导;烧结中期,收缩机制占主导,并抵消膨胀机制的作用;烧结终结前,膨胀机制略占主导. |

| Abstract: | The interaction between two sintering mechanisms in Huadong model was discussed by mathematical method. It was found that there exist two mechanisms in sintering process. The expansion mechanism plays main role in primary sintering stage, shrinkage mechanism plays main role in mid and high temperature sintering stage and devours the effect of expansion mechanism, and expansion mechanism may show its existing slightly before the end of sintering process. |
