The in-service doctoral program of fluid machinery and engineering specialty in Lanzhou University of Technology was formerly a hydraulic machinery specialty established by the Power Department of Harbin Institute of Technology, and it was the earliest fluid machinery engineering discipline established in China. This discipline is the first batch of master's degree-granting disciplines approved by our school, and it has also obtained the right to award doctoral degrees in fluid machinery and engineering. Thus, a multi-level and multi-standard talent training pattern and discipline construction system for doctors, masters, engineering masters and bachelors has been formed. It was rated as the first batch of provincial key disciplines and the second batch of provincial key disciplines in Gansu Province.
