摘　　要：判断混合气体爆炸性常用 3种方法 ,即科瓦德爆炸三角形法、美国矿业局采用的爆炸三角形计算法和最小助燃氧浓度法 ,然而如何准确、快速、形象地得到分析结果在防灾救灾中是十分关键的。笔者的重点是提供一个图形分析方法解决上述问题。VC ++是方法的基本理论依据 ,用一个实例来验证方法的有效性。总之 ,研究表明 :图形分析法可提高安全管理效率。Explosiveness of mixed gases is usually determined by three methods,namely,Coward explosive triangle method,explosive triangle calculation method adopted by U.S. Bureau of Mine and minimal combustion-supporting oxygen concentration method. However,how to get the analytical result visually,precisely and rapidly is very critical in disaster prevention and rescue. A graphic analysis method for solving the question mentioned-above was emphatically provided. The fundamental theoretical criterion of the method is based on VC++. The validity of the method was verified with a real case. The result showed that the graphic analysis could raise the efficiency of the safety management.
