The software has been completely mature and finalized after many years of upgrading and optimization. Educational scholars at home and abroad have also found the teaching advantages of the platform. On the basis of flipping the classroom, this paper will add the micro-curriculum technology to make the course and the flipping classroom integrate effectively in the teaching mode, and complete the reconstruction of the content and curriculum of the teaching course. The traditional teaching mode of engineering fluid mechanics is transformed into the "flipping classroom" teaching mode to improve teachers' teaching effect and students' learning The goal of the outcome.
