On December 14, the "top ten global engineering achievements in 2021" selected by the journal engineering of the Chinese Academy of engineering was released in Beijing. "Top ten global engineering achievements in 2021" is a major achievement of Engineering Science and technology with global influence, which has been completed in the world in recent five years. It can reflect the current highest level of Engineering Science and technology in one or more fields, The novel coronavirus pneumonia is the following: "AlphaGo and AlphaFold", "CRISPR/Cas9 gene editing technology research and application", "extreme ultraviolet lithography system", "fifth generation mobile communication technology", "500 meter spherical radio telescope", "hybrid rice", "insight radar landing detector", "public health and epidemic prevention against new crown pneumonia", "Yangtze River Three Gorges Project". "UHV transmission project". It is reported that in order to promote engineering progress, lead engineering innovation, give full play to the academic leading role of academic journals, and guide the global public to pay attention to and support engineering, engineering began to organize the selection of the world's top ten engineering achievements this year. The editorial board of engineering, a journal of the Chinese Academy of engineering, and experts from the "global engineering frontier" project team of the Chinese Academy of Engineering jointly served as the selection committee. Following the three principles of independence, objectivity and scientificity, the "top ten global engineering achievements in 2021" were finally determined through global solicitation and nomination, expert selection and recommendation and public questionnaire survey.
