Research And Development Of Simulation Software For Physical Chemistry Experiment

Experimental Physical Chemistry plays a vital role in the basic chemistry experiment of university, mainly developing students of the experimental, capabilities, exploring new knowledge capabilities, thinking ability logically and innovating ability. Physical chemistry experiments throughout all the chemical experiments, which contain many of the classic experiment, give the students a big help in learning physical chemistry. Physical chemistry experiment is a highly comprehensive experimental course, the strictly logic behind it, diverse methods and followed the era of technology continues to progress, so to provide students with more thought and imagination, and to cultivate innovative thinking chemistry majors has an indispensable role, but it often occur many problem in practice, Firstly, a large consumption of the experiment of drugs has resulted in higher costs; Secondly, the presence of some of the security issues can not be completed experiments; Thirdly, experimental repeatability is poor and big data error. To solve this problem, using the improvement of the operation of the conventional apparatus, and greatly improving the reliability of data acquisition time and data.However, the use of this instrument has led to several problems:Firstly, the number of pieces of equipment units less than normal, you can not guarantee that every student can master all experimental; Secondly, the vast majority of physical chemistry experiments involving the use and operation of the instrument and give students brought greater difficulties about the preview and review; Thirdly, The traditional experiment teaching method is difficult to highlight the talents training objective.In view of the above problems, this work is mainly on the basis of experimental operation of proficiency, through the CorelDRAW graphics software, will be required in the form of pictures of the experimental apparatus into the LabVIEW software interface, namely the front panel of the LabVIEW, formed a vector throughout experimental operation, part of the vector into LabVEW control, and then write the rear panel of the LabVIEW block diagram and use it to control these controls, so that the components can be experimental apparatus coherent operation. Using LabVIEW software provides the conditions for the experimental data, the panel can be rammed to show the data processing graphics on the front panel. To be integrated throughout the experiment, the experiment also need to add the name of the LabVIEW front panel tab, experimental purposes, the experimental principle, experimental procedures, results and data processing and precautions. Students’operation error occurs in the real operation, the experimental results can lead to inaccurate or produce large errors, the experimental simulation program or alarm information by writing prompts to prompt students to operate correctly.The work for the university physical chemistry experiment, developed a series of physical chemistry experiment simulation software, step by experiment and simulation experiments in the case of actual operation, comparative experiments and found that the actual experimental operation of complex, prone to operator error, big error to get the data. Operating clear interface simulation experiment principle and instrument structure at a glance, users can do anytime, anywhere as long as there is a virtual computer simulation, Lab VIEW software has a good interactive, more flexible than traditional experimental richer. Although virtual experiment can not completely replace the traditional simulation experiments, but plays an important role in fostering students’ creative thinking ability, which is a way to improve students’ interest in effectively teaching methods.
