法国煤炭调查研究中心为分析矿井通风网路而开发了计算机软件程序,该软件以人机对话的方式输入、输出数据,并有图形显示。象 Vendis 这样的计算机系统允许用户使用人机对话的微机相图形显示来建立、修改、显示和计算矿井通风网路。通风网路可用数字的方式输入到计算机中,并在操作台显示图 The French Center for Coal Research and Development has developed a computer software program for the analysis of mine ventilation networks. The software inputs and outputs data in a man-machine dialogue with a graphical display. Computer systems such as Vendis allow users to create, modify, display, and calculate mine ventilation networks using computer-based graphical displays of human-machine conversations. The ventilation network can be digitally entered into the computer and displayed on the console
