| 摘 要： | 为了探讨瓦斯防爆的综合指标，依据现代系统的理论的能量观点，建立了瓦斯传爆的比熵界限及温熵图，该图是瓦斯传爆的能流界限图，它比现用的瓦斯浓度三角形更加全面准确，借助耗散结构理论，分析了瓦斯防爆的负熵机理，并对惰性气体的抑爆浓度等实验数据作出了理论解释。

| Abstract: | In order to investigate the comprehensive indices of gas explosion proof, the specific entropy limit and Temperature-Entropy(T-E) diagram were established based on the energy viewpoint of modern system theory. The T-E diagram is the energy limit diagram of gas ignition,which is more complete and accurate than that of gas concentration triangle being used currently. With the aid of dissipation structure theory, the negative entropy mechanism of gas explosion proof is analyzed and the experimental data of inert gas concentration for inhibiting explosion is theoretically explained. |
