将蒸汽管网的结构用典型的数据结构模型——二叉树模型进行描述，在此模型基础上根据规范和设计参数进行蒸汽管网管径和保温厚度的程序化设计，并建立目标函数和约束对其进行优化，按经济性的优劣，依序列出多组设计方案可供设计选择，同时对优化计算的可行性和有效性进行了讨论。

英文摘要：

The structure of the steam network is described by the binary tree model which is the typical data structure model, and the pipe diameter and heat insulation thickness of the steam network are designed according to relevant specifications and parameters. The object functions and constraints are developed to optimize the design, and several design schemes for further selection are given. The feasibility and effectiveness of the modeling and optimization are discussed.
