中文摘要：
针对预测多种尺度颗粒随机分布复合材料等效热传导参数的难点，提出了一种多尺度有限元方法．首先，根据材料的特点，描述了多种尺度随机颗粒复合材料，然后基于多尺度分析结果，运用有限元方法获得了计算等效热传导参数的算法，最后用实例说明了此算法的有效性和收敛性．
英文摘要：
A finite element （FE） method for the prediction of the equivalent heat transfer parameters of the composite material with random multi-scale grains was presented. Firstly, the composite material with random multi-scale grains was briefly described. Next, a finite element method was described. Finally, a numerical example was given. The numerical result has shown that the FE method based on statistical multi scale analysis （SMSA） is an effective method for the prediction of the equivalent heat transfer parameters of the composite material with random multi - scale grains.
