Almost all MIS oriented CASE tools support. DFD description and generation. DFD maybe automatically generated according to the description in fotmal language statements or created interactively. Basing on the upper CASE analysis tool developed by the author, the paper discusses the following techniques involved in crcnting DFD interactively under picture menu driven environment: the data structures of graph segments and graph files, the operations applied over the files, the realization of DFD hicrachical architecture-creation of sub-DFDs, DFD scaling and translation by means of transformation between world and device coordinate systems, as well as windows and viewports, Being different from addressing common interactive graphics systems. the paper especially discusses the issues of extracting logical relationship form DFD, verifying the relation consistency and integrity.

面向管理信息系统的计算机辅助软件工程(CASE)工具几乎无例外地支持数据流程图(DFD)的描述和生成.在实际建立了一个上游CASE工具的基础上,文章讨论了在图形菜单驱动下交互建立DFD的几项技术:图形段的数据结构、图形文件数据结构以及对图形文件的操作,DFD层次结构的实现——子图的建立方法、通过座标体系变换和窗口与视区的映射实现DFD的比例变换和平移.不同于研究一般通用绘图系统,文章专门研究了如何从DFD中抽取逻辑关系并对它们进行完整性和一致性检验.

With the objective of electric Power papers,this paper puts forward an efficient isolationand recognition method of the graph segments. It uses the boundary tracing technology intothe isolation and gives an efficient method of selecting drawing lines in graph segments,which can greatly enhance the speed of isolation and the accuracy of recognition.

以电力图纸为目标,提出了一种有效的图段符号自动分离与识别的方法.用边界跟踪来进行图段分离,给出了有效抽取图段符号笔划的方法,从而大大地提高了分离的速度和识别的精度.
