摘　　要：以牡丹江东部的穆棱沸石矿床为例,探讨了天然沸石矿矿石不同物化性能间的相关规律。研究表明,天然沸石矿矿石的K+交换容量、热失重值、吸湿率、气体吸附容量等与NH+4交换容量、矿石的耐酸性及热稳定性之间,均具有较明显的正相关性;矿石的耐酸性、热稳定性与NH+4交换容量之间的相关性不明显;而矿石的比表面积与比辐射率之间却有较明显的负相关性。天然沸石矿矿石不同物化性能之间的负相关性称为"不同物化性能之间的制约性",这种"此优彼劣"性能的研究,对天然沸石矿的综合利用和最佳利用具有重要的指导意义。As a case study of Muling zeolite deposits in Eastern Mudanjiang, this paper has discussed the correlativities between different types of physical-chemical properties of natural zeolites.Studies show that there are obvious positive relativities between CEC of NH~^+__4 and CEC of K^+,TG values, hydroscopicity and gas adsorptivities of natural zeolite ores, and also between resistance to heat and to acid. But the relativities are less obvious between CEC of NH~^+__4 and resistance to heat and to acid. While there is negative correlation between specific surface areas and specific radiant emittances of zeolite ores, the conditionality between different types of physical-chemical properties. Therefore, it is highly important to study the conditionality for comprehensive utilization and the best utilization of natural zeolites.
