摘要
通过分析地铁火灾特性,强调预防地铁火灾的重要性。从地铁火灾成因入手,从源头上避免火灾发生。分析地铁火灾系统的耗散结构特性,揭示各影响因素变化所引起的系统熵值变化。建立地铁火灾系统熵流模型,进行熵流计算。提出预防火灾的措施,增加负熵,克服正熵,控制火灾演变方向,使其向着减少火灾发生以及降低损失的方向有序发展。
By analyzing the characteristics of subway fire, the im- portance of the prevention of subway fire was emphasized. Starting from the subway fire causes, avoid fire accident from the source. Analyzed the characteristics of dissipative structure in subway fire system, and revealed the entropy changes caused by the change of the influence factors. Established entropy model of subway fire sys- tem, and conducted entropy flow calculation. Put forward the fire prevention measures, to increase the negative entropy, overcome entropy, and control the evolution direction of the fire, to reduce the fire and the loss.
