摘　　要：利用VisualC++6. 0实现了燃气管网水力计算图人机对话的计算机输入。采用双向循环链表的数据结构,解决了点捕捉和线捕捉问题。实现了绘制管段、输入注释、删除管段、截断管段、改变管段流向、改变管段颜色等过程。The computer input with man-machine-dialog for hydraulic calculation drawing of gas network is realized with Visual C++6.0. Applying data structure of dual cycle linked list, the problems of snapping points and snapping lines are solved, and some procedures, such as drawing pipeline section, inputting notes, deleting pipeline section, stopping pipeline section, changing flow direction and color of pipeline section are realized.
