中文摘要：

用NaCl作熔盐介质制备镁橄榄石质多孔材料，用灰色系统理论研究了在不同NaCl含量（30％、40％、50％和60％）以及不同烧成温度（1000、1050、1100和1150℃）下材料的气孔特性与耐压强度的关联性。结果表明：相同烧成温度、不同熔盐含量时，多孔材料的耐压强度与材料内部气孔孔径在4．6～46um范围内的数量关联度最大；不同烧成温度、相同熔盐含量时，孔径分布在46-84um之间的气孔数量对多孔材料的耐压强度关联度最大。

英文摘要：

Forsterite porous materials were prepared with NaC1 as a molten salt medium. The correlation between the pore characteristics and cold crushing strength of the materials at different NaC1 contents （i.e., 30%-60%） and firing temperatures （i.e., 1 000-1 150℃） was investigated based on the gray system theory. The results show that the grey relational degree between the cold crushing strength and the pore size distribution of 4.6-46.0um is greater than that between the cold crushing strength and the other pore size distributions when the samples are sintered at 1 100℃ at different NaC1 contents. And, the correlation coefficient between the cold crushing strength and the pore size distribution of 46.0-84.0 um is the greatest when the samples with the same content of NaC1 are sintered at different temperatures.
