CAI Computer Programs of Chemical Engineering for Technical College Students.

本研究的目的是开发五年制“工学院”化工专业CAI计算机程序。许多数值方法和计算机图形技术的子程序首先是用FORTRAN 77语言以通用风格开发的。用上述子程序和子程序编写了许多用FORTRAN 77编写的化工实例和问题的程序。然后用BASIC语言编写了流体流动、传热、蒸发、蒸馏和吸附等领域的程序，使计算结果以计算机图形或表格形式显示。最后将所有程序编排成一个宏程序，完成了CAI系统。任何领域的任意问题都可以从软盘加载到个人计算机的存储器中，然后运行，然后只需按一下键，计算结果就可以彩色显示。在蒸发器设计程序中，可以将三效蒸发器运行时的视频图像叠加在CRT显示器上。通过“触摸屏”上指定点的推动，取代反应器周围的泵、阀等设备的操作，制定了搅拌槽式反应器启动操作培训方案。这有利于高职学生对化工专业的理解。

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.
