bosh diameter(bosh diameter - The diameter of the inside face of the lining at the bosh line. This is also the diameter of the straight section above the bosh. 炉腹直径 (bosh diameter) 指的是炉腹上水平线处炉衬内表面直径；亦可指炉腹以上竖直段直径。)
distribution of pore diameters(The influence of the distribution of pore diameters on the R 1, 000 (the reduction rate at 1, 000°C) was studied under the condition of the similar total porosity and gangue content, and it was found that the pores 15μm or less in diameter have a significant influence on reducibility of sinter. 在总孔隙率和脉石含量相似的条件下，研究了空隙直径分布对 R1 000(1000°C 时的还原率)的影响。结果发现，直径 15μm 及以下的空隙对烧结矿还原性具有重要影响。)
