摘要
研究软件工程技术在液压启闭机ＣＡＤ系统中的开发及应用．通过绘制数据流图、编制数据词典以及由数据流图导出液压启闭机ＣＡＤ系统的软件结构图等工作，完成了液压启闭机ＣＡＤ系统分析与设计．
The hydraulic operated gate lifting device CAD system using software engineering technique is researched. By drawing data flow diagram, compiling data dictionary, obtaining dtructure chart through the data flow diagram, the analysis and design of hydraulic operated gate lifting device CAD system are worked out.
