本文以文献［２］为基础，提出了一种通用于单相受热面工作过程实时数字仿真和工程定量分析的动态数学模型及其算法。其主要特点在于：（１）该算法在很大的积分时间步长范围内具有良好的计算精度和数值稳定性；（２）文中所建立的分布参数模型只有一个可调的变量△τ，针对不同的应用场合，选用适当的△τ，即可满足对模型运算速度或计算精度的需求。
Based on the literature [2], this paper presents a dynamic mathematical model and its algorithm which is commonly used in real-time digital simulation and engineering quantitative analysis of single-phase heating surface working process. The main features of this algorithm are as follows: (1) The algorithm has good accuracy and numerical stability over a large range of integral time steps. (2) The distribution parameter model established in this paper has only one adjustable variable △ τ, Different applications, the choice of the appropriate △ τ, to meet the model calculation speed or calculation accuracy requirements.
