8. Diagnostic testing method for torsional vibration faults: Various faults can be diagnosed through micro angular velocity fluctuation testing.

Wenzhou University has formed a multi-level and multi form educational pattern, including undergraduate education, graduate education, continuing education, international student education, and international cooperative education. Its disciplines cover economics, law, education, literature, history, science, and engineering. There are eleven major disciplines including medicine, management, art, and interdisciplinary studies, with 20 professional colleges and Rongying College, Su Buqing College, and three undergraduate colleges. In 2011, Wenzhou Kean University was established in cooperation with Kean University in the United States. In 2016, Wenzhou University City College was transformed into Wenzhou Business School, and in 2021, Wenzhou University Oujiang College was transformed into Wenzhou University of Technology.

There are 1.8949 million volumes of books and e-books, as well as 97 electronic journals and databases in both Chinese and foreign languages. The teaching staff is strong, with a total of 2268 staff members, including 1432 full-time teachers (968 from Botu, accounting for 67.60%). There are 38 national level talents, including full-time academicians, candidates for the National "Ten Thousand Talents Plan", selected candidates for the National Talent Introduction Plan, Changjiang Scholars, National Outstanding Youth, National Young Experts with Outstanding Contributions, National "Hundred, Thousand, Thousand, Thousand Talents Project" candidates, National Excellent Youth, Cultural Masters of the Central Propaganda Department, and "Four Batches" talents. There are currently 186 high-level talents at or above the provincial level, and they have been approved as national talent introduction demonstration bases. It has national model worker, national model teacher, national May Day labor medal winner, national outstanding teacher, national March 8th Red Flag bearer and other national teaching and education models

Fan. The school has achieved remarkable results in discipline construction, with one doctoral degree authorization point in a first level discipline, 18 master's and earth's degree authorization points in a first level discipline, and 20 master's and earth's professional degree authorization points. It also has a postdoctoral workstation in Zhejiang Province and collaborates with 25 well-known universities and research institutions at home and abroad to train doctoral and earth's postdoctoral students. Ecology is an advantageous characteristic discipline of Zhejiang Province under the joint construction of provinces and cities. Nine disciplines, including chemistry, Chinese language and literature, electrical engineering, law, Marxist theory, applied economics, mechanical engineering, ecology, and civil engineering, are first-class disciplines in Zhejiang Province. Four disciplines, namely chemistry, materials science, engineering, and computer science, have entered the top 1% of ESI globally.
