【Abstract】 The Unity 3D,Flash and other technologies are used to construct and contrast virtual experiment system with strong function, immersion and interaction for the titrimetric analysis, that could be well used in the PC terminal and mobile terminal which includs most of the titrimetric analysis experiment for current chemical and other professional institutions. Considering the specific characteristics of titrimetric analysis experiment, the simulation includes experimental process, experimental phenomena and results that comprise the whole process of titrimetric analysis. Through the function of setting the reference material and selecting the quality,indicator, solubility and dropping speed, multi parameter and multi variable are used to realize the multi process real time data transfer in the virtual experiment. The titrimetric reaction curves is also added to the system to complete the function of real time titrimetric process to give comprehensive data processing and results evaluation. Also a complete titrimetric analysis of virtual experiment of real-time tracking and evaluation system is established to lay the foundation for the individual and automatic learning ability to make a meaningful exploration for the development of new-form virtual laboratory.更多还原
