建立粒度对颗粒填充影响的模型需要考虑两个方面：（1）单一粒度颗粒的填充时需要把起始孔隙度考虑进去；（2）混合粉体的填充时，把填充体积比作为反映颗粒之间反应的量度。通过实验对以上假设作了检验。实验内容是用白色熔融氧化铝测量标准注入和轻压填充密度。结果表明，由 Two aspects need to be considered in establishing a model of the effect of particle size on particle packing: (1) the initial porosity needs to be taken into account when filling a single particle; (2) the filling volume ratio is taken as the particle size Measurement of the reaction. The above hypothesis was tested through experiments. The experimental content is measured using white fused alumina standard injection and lightly packed density. The results show that, by
