【 摘 要 】

Aiming at shortcomings of depending on experiences and inferior computation accuracy brought by using linear interpolation to calculate fixed pressure burning temperature, a new method using iteration was put forward. Moreover, the optimization model to calculate equilibrium ingredients was formulated based on the new method, and sequential quadric programming method rather than Lagrange multiplier was used to compute the model. At last, a numerical example was given to validate the method in this paper. Results make show that more perfect outcomes can be achieved through the method in this paper than classical method.
