摘　　要：文章根据热阻控制及网络拓扑学的相关理论,提出一种较为简便的节点分析方法求解受热变形体的温度场,文中通过求解一系列的节点网络方程得到了各节点温度场的数学表达式,并进行了不同边界条件下各节点温度变化的仿真研究,得到的温度曲线与其它方法所得结果基本吻合,从而验证了节点分析法的有效性。This article proposed a new simpler method called nodal analysis method to solute temperature field of heat transfer body of the thermal current controller according to the thermal resistance control theory and the network analysissitus theory. Mathematical model of each point＇s temperature transformation is obtained through solving a series of link points network equation in the article, and the simulation of temperature change under the different boundary condition has carried out. The temperature curve obtained by this means is accord with that of other ways. thus confirmed the nodal analysis method.
