Gymnastics textbooks used in regular colleges and universities has experienced decades of development and needs to be revised and improved under the current physical education situation in colleges and universities, so as to make the content more suitable for needs of college students. This paper adopts literature review, comparative analysis and statistics analysis method to study on the existing gymnastics textbook for physical education major in regular colleges and universities in China by combing development of textbook, summarizing the content and structure, exploring problems existing in the design of textbook in recent years, and then proposing certain improvement suggestions on gymnastics textbook for physical education major.展开更多

That is, if the transfer functionσ: R→R is non-polynomial and integrable function on each finite interval, F may be innorm approximated by fuzzy valued functions defined as to anydegree of accuracy. Finally some real examples demonstrate the conclusions.展开更多

Universal approximations to some continuous fuzzy functions defined on F 0 (R) n by the four layer fuzzy neural networks are shown. At first,multivariate Bernstein polynomials associated with fuzzy valued functions are empolyed to approximate continuous fuzzy valued functions defined on each compact set of R n . Secondly,by introducing cut preserving fuzzy mapping,the equivalent conditions for continuous fuzzy functions that can be arbitrarily closely approximated by regular fuzzy neural networks are shown. Finally a few of sufficient and necessary conditions for characterizing approximation capabilities of regular fuzzy neural networks are obtained. And some concrete fuzzy functions demonstrate our conclusions.展开更多
