【Abstract】 The analytical method of Ω－Ｈ diagram is introduced briefly, and the expression of chemical reaction process on the diagram is given. The transformation procedure of synthetic ammonia is analyzed with this method and the initial process is modified. The results prove that the method of Ω－Ｈ diagram is a powerful tool for the analysis of chemical process.更多还原
