用等效反应温度法计算轴向扩散模型

CALCULATION OF THE AXIAL DISPERSION MODEL ──THE EQUIVALENT REACTION TEMPERATURE METHOD

运用等效反应温度法，将一个在温度Ｔ下进行的ｎ级反应等效成在温度Ｔ．下进行的一级反应。从而大大简化了轴向扩散模型的计算过程，并获得了该模型的近似解析解。计算结果与数值解相比，绝大多数偏差小于３％。

By use of the equivalent reaction temperature method,the nth order reaction in temperature T was regarded as the 1st order reaction in temperature Te. Complications in calculations involved in axial dispersion model can be much simplified,and the analytical solution of this model was obtained. Compered with the numerical solution, the deviations of results are less than 3%.
