研究了多孔材料阻隔瓦斯爆炸效果的定量评估方法，分别建立了基于超压、火焰温度的评估数学模型。引入熄爆参数概念，结合衰减爆炸超压和衰减火焰温度评估方法，建立基于熄爆参数的多孔材料阻隔爆效果综合定量评估数学模型，并确定瓦斯爆炸理想阻隔爆效果区域。利用综合评估法中的乘积熄爆参数法对多孔材料瓦斯爆炸阻隔爆效果进行综合定量评估及优选，结果表明，综合定量评估算法模型既能反映抑制压力的效果，又能反映阻隔火焰的效果，可用于阻隔爆效果评估，为多孔材料在实验和工程应用过程中的性能评定提供科学依据。

By studying the quantitative evaluation methods of porous materials suppressing and isolating gas explosion,the evaluation mathematical model based on overpressure and flame temperature were proposed. Through introducing a concept of quenching parameter and combining evaluation methods of pressure inhibition and flame suppression,a new comprehensive quantitative evaluation mathematical model was proposed.The region of ideal suppression and isolation effect of gas explosion was determined.The product -quenching parameter evaluation method one of comprehensive quantitative evaluation model was used to quantitatively assess effect of inhibition and suppression and optimize porous materials.The results show that the effect of pressure inhibition and flame suppression are reflected in the model,which can be used to evaluate effect of gas explosion suppressing and isolating and provide scientific basis for porous material performance evaluation in the experiment and engineering applications.
