摘　　要：在所定义的当量长度与当量周期的基础上，采用数值方法与矩阵理论建立空气预热器的线性数学模型来研究动态特性及稳态温度分布情况，得出工质的阶跃曲线，并指出当量周期步长及当量长度步长的比值决定能否收敛，而收敛速度的快慢则与矩阵的主特征值有关。This paper develops the linear modsl with numeric method and matrixtheory to study the dynamic character and steady temperature distrlbution of the regenerativeair preheater based on the reduced length and the 'reduced period. The ratio of the reducedlength to the reduced period determines convergertce or not and the speed of the convergencejs dependent on the dominant eigenvalue of a matrix.
