Abstract:

Currently， complex engineering innovation experiments are difficult to be performed because of the limitation of experimental condition and operating environment. This leads to the lack of cognition of advanced technology and shortage of engineering practical ability on chemical engineering. Aiming at this problem， mixed teaching model by combining actual operating and virtual simulation was carried out in the chemical engineering specialty experiment. The virtual experiment can greatly reduce the risk of experiment operation and overcome the shortage of time-consuming and sever experimental condition. It is beneficial to promote the reform and development of practice teaching of chemical engineering specialty. The process evaluation system of theorical learning， exercise test， process design， experimental operation and report processing in simulation experiment could cover the whole learning process. It thus could systemically reflect the ability of students for the knowledge acquirement and comprehensive practice. In the CO low-medium temperature catalytic conversion simulation experiment， the average achievement degree of the four course objectives is 0.80， 0.91， 0.83 and 0.73， respectively， implying an excellent teaching effect. Practically， the virtual simulation experiment can focus on the actual application. Through the novel experimental content design， it is easier to induce the enthusiasm and initiative of students. It is an effective approach to enhance the ability to solve complex engineering problems.
