The Research And Exploration Of The Mode And Method Of The Virtual Titrimetric Analysis Laboratory

With the development of time,the virtual learning of experiment has become important way to acquire knowledge. Especially for the new generation of students,who are looking forward to get more personalized learning and diverse learning needs.The function of high performance virtual laboratory is also put forward to more requirements. At present,the research focused on intelligent virtual laboratory has been widely spreaded in the world, because intelligent virtual laboratory can effectively meet the students need that they want to grasp more professional knowledge in fastest and fragmental time, intelligent virtual laboratory also has a sense of immersion characteristic of virtual reality,makes learners try to do experimental practice repeatedly. These advantages are helpful to improve skills training and develop the virtual laboratory equiped with professional skills. Titration analysis experiment is the basic content of analytical chemistry, and also is the major skills to the students of chemistry and chemical engineering.In the learning of professional courses and experimental courses those students must master the Titration analysis skills as for a basic task. Titration experiments has some different characteristics beween other chemical experiments, how to construct the virtual laboratory of titration analysis and the function is a meaningful and challenging work.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.
