Abstract

Abstract:

In situ variable temperature X-ray diffraction is a comprehensive and innovative experimental project in physics, chemistry and other related disciplines. Therefore, it is necessary to develop an in situ variable temperature X-ray diffraction virtual simulation experiment system based on the guiding ideology of "combining virtual and real experiments, replacing the reality with the virtual". This system completely simulates the actual experimental scenes of instrument recognition, sample testing, data calculation and application, etc. Teaching adopts online and offline combination of virtual and reality teaching methods, which cultivates students' comprehensive ability and advanced thinking to use large instruments to solve complex problems.

Key words: In situ variable temperature X-ray diffraction, Virtual simulation, Laboratory teaching
