| 摘 要： | H2，CO，CH4是化工生产中常遇到的混合气体，若与空气混合，一定条件下就构成多元爆炸性混合气体，浓度爆炸极限是一个关键性数据。对于多元可燃性混合气体，主要采用Le Chatelier经验方程或对其进行改进后的公式进行估算，但Chatelier经验方程只适用于烃类的混合气体与空气的混合物，对于含氢的多元爆炸性混合气体，预测误差很大。本文对大量的浓度爆炸极限数据进行了多元线性回归分析，建立了爆炸极限预测模型，对于指导多元混合气体支链燃烧与爆炸的理论研究和实践，具有一定的参考价值。

| Abstract: | The concentration explosive limits of polybasic explosive mixture gas of synthetic ammonia containing H_2,CO,CH_4 were systematically researched under ambient conditions.The regression eguations of explosive limits-concentrations were determined with the computer software SPSS.The results showed that the relative contents of H_2,CH_4 and CO had obvious effect on explosive limits,and the theoretical model was in good agreement with experment. |
