CAI Computer Programs of Chemical Engineering for Technical College Students.

本研究的目的是开发五年制“技专”化学工程计算机辅助教学程式。许多数值方法和计算机图形技术的子程序都是用FORTRAN 77语言开发的。用上述子程序编制了许多用FORTRAN 77语言编写的化工例题和问题的程序。然后用BASIC语言编制了流体流动、传热、蒸发、蒸馏和吸附等方面的程序，使计算结果能用计算机图形或表格形式显示出来。最后，通过将所有程序编排成一个宏程序，实现了CAI系统。该程序可将任何领域的任意问题从磁盘装入微机内存，运行后，只需按键，计算结果就可彩色显示，在蒸发器设计程序中，可将三效蒸发器运行的视频图像显示在CRT显示器上。开发了一套搅拌釜式反应器启动操作培训程序，通过在“触摸屏”上按下指定点来代替对反应器周围泵、阀等的操作。这对提高高职学生对化学工程的理解有着重要的意义。

The object of this research is to develope the CAI computer programs of chemical engineering in "Technical College" which is the five-year term school. The subroutine subprograms for many numerical methods and computer graphics techniques were first developed in universal style with FORTRAN 77 language. Many programs written in FORTRAN 77 on illustrated examples and problems in chemical engineering were made with the above subroutine subprograms. Then many programs in the fields of fluid flow, heat transfer, evaporation, distillation and adsorption were developed in BASIC language, so as the results calculated were displyed with computer graphics or in a tabulated style. Lastly the CAI system was accomplished by arranging all programs for a macro-program. Arbitrary problem in any field can be loaded from a diskett to memory of a personal computer, and is run, and then the calculated results are displayed colorfully by only key touches.In the program of evaporator design it is able to superimpose the video-image of triple-effect evaporators in operation on a CRT display. A program for training of start-up operation of a stirred tank reactor was developed by replacing the handling of pump and valve and some others equipped around the reactor by the pushing of the specified point on the "Touch screen". This gacilitates the students' comprehension about chemical engineering in technical colleges.
