VI. Admissions Information
The team provides a good learning atmosphere and research environment, with independent workstations, studios, and other facilities equipped with central air conditioning. Regular team work meetings are held, where students report academic progress and supervisors are present throughout the entire process to provide guidance. Graduate students have the opportunity to participate in high-level academic lectures organized by relevant disciplines within the university every month.
The team has sufficient research funding, allowing each graduate student to independently design and manufacture non-standard equipment or systems for conducting indoor experimental research. For outstanding students from families facing difficulties, efforts will be made to solve their tuition fees. At the farewell symposium for fresh graduates held every summer, academic achievement awards of corresponding amounts will be given to current students and alumni based on their actual output in terms of paper publication, patent application, and other aspects over the past year.
The team provides all students with at least one opportunity to participate in professional academic conferences at home and abroad, and at least two opportunities for field research and learning outside Beijing, to broaden their horizons, expand their vision, and enhance their qualities. The team works closely with enterprises and institutions affiliated with super-large central enterprises such as Sinopec and CNOOC, and can provide practical training opportunities at or close to the front line of enterprises, allowing students to experience the work of enterprise engineers. Three years of graduate study is equivalent to accumulating three years of work experience.
The team regularly organizes a variety of cultural and recreational activities every year, such as outdoor excursions, team-building events at home, birthday celebrations, ball games, allowing everyone to feel the warmth and care of a "family". Especially in light of the progress of the research projects in which graduate students are involved, there are often opportunities for in-depth exchanges with corporate experts or engineering technicians, which are equivalent to multiple "project team-building" activities.
