In discipline construction, Tianjin University has formed a discipline layout which focuses on engineering, combines science with engineering, and develops economy, management, literature, law and education in a coordinated way. There are 57 undergraduate majors, 35 first-class master majors, 27 first-class doctoral majors, and 2 1 postdoctoral research stations. There are 7 national key disciplines (covering 2 1 two disciplines) with first-class disciplines, namely: optical engineering, instrument science and technology, material science and engineering, architecture, hydraulic engineering, chemical engineering and technology, management science and engineering; In addition, the two disciplines have eight national key disciplines, namely: fluid mechanics, mechanical design and theory, power machinery and engineering, power system and automation, microelectronics and solid-state electronics, communication and information systems, detection technology and automation devices, and structural engineering; There are two national key disciplines (training) in the two disciplines, namely: general mechanics and mechanical foundation, technical economy and management; There are 27 key disciplines in Tianjin. In the results of the 20 12 discipline evaluation published by the Center for Degree and Postgraduate Education Development of the Ministry of Education (known as the third discipline evaluation in the industry), Tianjin University 14 discipline has entered the national 10 top, two more than the previous round. Eight disciplines entered the top five in China, an increase of 1 compared with the previous round. Among them, the discipline of chemical engineering and technology once again won the national 1, achieving three consecutive championships; The discipline of management science and engineering rose from the eighth in the last round to the second in the country; Instrument science and technology, optical engineering and architecture rank third in China respectively. The discipline of ship and ocean engineering ranks fourth in the country; Water conservancy projects and landscape architecture rank fifth in China respectively.
