| 摘 要： | 本文运用热力学第二定律,从单组分气体爆炸反应出发,借助于耗散结构理论,建立了熵产生与爆炸极限的关系,进一步推导出了单组分气体爆炸极限的计算公式并推广至计算多组分混合气体爆炸极限的计算公式.计算结果与实测值相近.本文旨在为瓦斯防治工作提供较全面的定量理论依据.

| Abstract: | From the reaction of the single component gas explosion,we set up the relationship between the entropy production and the explosion limits by making use of the second law of thermodynamics and dissipative structure theory,further inferred the calculation formula of explosion limits of single components and mixed explosive gas.The computed result and the detected value are close.This article aims to provide a more comprehensive theory for gas prevention and control. |
