By using the method developed in the former paper and Order Analysis method
the features of multiple states have been investigated when a strongly exothermic irreversible reaction occurs. The results show that three states may appear in some domain of φ when γ and β are large. When γ increases or θ decreases
the multiple states zone becomes large
but its shape doesnt change. A cone -simplification method is developed to predict the multiple states zone and its accuracy is satisfactory compared with that from numerical calculation.
