【Abstract】 Several techniques of 3D molecular simulation based on Web page were introduced, which are VRML, Chime, Chem3D and HyperChem plugins. Their advantages and shortcomings were also discussed.The rotations, zooms, transformations can be operated interactively, and several color and display modes are also available. 3D molecular simulations can improve performances of chemical network courses and enhance educational effects. They are important techniques on developing the long distance educations.更多还原
