Research on Key Techniques of Dynamic Simulation in Chemical Virtual Teaching
To improve the quality of chemical virtual teaching,key dynamic simulation techniques used in chemical virtual teaching are analyzed.The combination of modular mechanism modeling method,Oracle distributed database and improved multivariate universe optimization algorithm is adopted to realize the dynamic simulation of chemical process.The modular mechanism modeling method models multiple parts of the chemical process and combines them through modular models to complete the simulation of the chemical case.Oracle distributed database stores the data in the chemical case,which enables multiple users to read and write to the database at the same time in different locations.The improved multivariate universe optimization algorithm introduces nonlinear coefficients,so that the algorithmic problem does not fall into local optimum.The creative combination of the three techniques ensures the stability of the simulation database,the high efficiency of data reading and the realism of chemical simulation in the process of realizing chemical dynamic simulation.After experimental verification,the use of multiple techniques can dynamically simulate chemical cases and meet the requirements of chemical virtual teaching.
