摘　　要：利用反推法求解锅炉启停及变负荷运行过程汽包温度场,建立数学模型,并将计算结果与理论计算结果相比较。结果表明,该方法计算准确度高,可以应用于实际工程。The temperature field is calculated with inverse method during boiler＇s start-up, shutdown and load change and a mathematical model are built. The calculated result by this method is compared with the theoretical result. The comparison shows that the accuracy of this method is very high and it can be applied to practical projects in security.
