英文摘要	In this paper, the production rates of quarkonia eta(c), j/psi, eta(b), y and b-c(()*()) c mesons through w+ boson decay at the lhc are calculated, at the leading order in both the qcd coupling as and in v, the typical velocity of the heavy quark inside mesons. it shows that a sizable number of quarkonia and b-c(()*()) c mesons from w+ boson decay will be produced at the lhc. comparison with the predictions by using quark fragmentation mechanism is also discussed. results show that, for the charmonium production through w+ decay, the difference between predictions by the fragmentation mechanism and complete leading order calculation is around 3%, and it is insensitive to the uncertainties of theoretical parameters; however, for the bottomonium and b-c(()*()) productions, the difference cannot be ignored as the fragmentation mechanism is less applicable here due to the relatively large ratio m(b)/m(w).
