摘要
应用灾变理论原理 ,建立了反映瓦斯爆炸过程的尖点模型 ,该模型将影响瓦斯爆炸的参数归结为瓦斯浓度和以点火能为特征量的不确定性因子两个控制参数和一个反映系统安全程度的状态参数 ;基于这种数学模型 。
Using the catastrophe theory, a cusp model for fire damp explosion is constructed. It consists of two control variables, damp consistency and uncertainty which is constituted of evocable factors, and one state variable. Based on the cusp function, an evaluation using Probabilistic Risk Assessment for fire damp hazard is presented to analyze safety state of system.
