针对连续加热炉，先建立段法模型，通过改变表面段规格寻找准确解，并以该结果为基准衡量三元模型。而在三元模型下，通过考察模型段和炉气黑度变化，寻找温度场的变化规律，最终得到三元模型的合理解。
針對連續加熱爐，先建立段法模型，通過改變錶麵段規格尋找準確解，併以該結果為基準衡量三元模型。而在三元模型下，通過攷察模型段和爐氣黑度變化，尋找溫度場的變化規律，最終得到三元模型的閤理解。

Aim to the reheating furnace the zonal method is developed .The exact solution is solved by changing the zone size.Then using the solution as a criterion to measure the ternary mode .In the other hand, based on the ternary model , the changes of model zones and gas emissivity values are inspected for searching the regulation of temperature zone changing .Finally, the accurate solution for ternary model is obtained .
