Virtual Simulation Experiment for Classifying and Identifying Substances Based on Dual-energy X-ray Imaging and Energy Dispersive X-ray Diffraction
A virtual experiment for classifying and identifying substances based on X-ray technology was designed based on a cutting-edge research combines dual-energy X-ray transmission imaging with energy dispersive X-ray diffraction system in order to rapidly and accurately detect contrabands on the application of security inspection.The experiment builds a comprehensive teaching environment for hierarchical teaching with several modules such as preview and visiting the virtual lab,instrument construction,operation and data processing,and expansion experiment.Students can learn the principles,experimental methods,and safety standards of X-ray technology for classifying and identifying substances,deepen their understanding of the principle of interaction between X-rays and substances,and cultivate experimental abilities and creatively science think.
