Research On The Virtual Experiment Platform Of The Chemistry In Middle School

With the rapid development of the computer technology, virtual experiment teaching is akind of new teaching mode into daily teaching activities. The traditional teaching experimentis faced with less experiment instrument and part of the experiment instrument has beenseriously damaged or behind. There are a lot of problems in the traditional teaching, such asthe derailment of operation, the shortage of funds, the limit of the experiment time, singleteaching form and there are a lot of risk factors in the experiment, changing the traditionalteaching mode of experiment is imminent.Currently, artificial intelligence, expert system applied in the virtual experiment is thefield of artificial intelligence research hotspot. One aspect of knowledge representation,various fields respectively have different knowledge representation method. How will theexperiment content, experiment, the experimental process steps and transformation ofaccurate information for the computer can read in virtual experiment, this problem is theknowledge that the focus of research.Based on the analysis and research of knowledge representation system and intelligentvirtual laboratory evaluation system of knowledge representation is without time and describethe constraint. So on the basis of previous studies based on new timing description logicsystem, the system of knowledge representation is suitable for virtual experiment testenvironment and intelligent information that needs aspects.
