Many of them choose to work in the fields that are not directly related to their thesis works, but they have the ability to adjust themselves to different environments as well as the basic scholastic ability.Wearestudyingtheatomsandmoleculesinthenear-wallregionbyconstructingnumericalcodesthatsimulatetheirreactionprocesses.ThecodeshavebeenusedinthedesignofITER:ITERisintendedtoprovetheviabilityoffusionasanenergysource,andtocollectthedatanecessaryforthedesignandoperationofthefirstfusionpowerplant.RFplasmadeviceinourlaboratoryisusedtotestourcodesbycomparingthecalculatedandobservedphotoemissionintensitiesoftheatomsandmolecules.Reaction processes of atoms and molecules.The cold spray gun nozzle produced in our lab. In the cold spray method, a coating is formed by exposing a substrate to high-velocity solid-phase particles, which have been accelerated by supersonic gas flow at a temperature much lower than the melting temperature of the feedstock.The composite (cermet) coating of the ceramic and metal superior by abrasion properties-resistant had been developed by high velocity flame (HVAF) spray.←The copper particle collided on steel substrate at 500m/s: A copper part spouts out into a fold (called “ material jet ”) form the interface with the substrate.
