A record of 149 goals in 481 appearances puts john radford in two arsenal top 10s 481场比赛进149球的记录让约翰拉德福德成为阿森纳10大射手中的一员。

Radford is best remembered for leading the forward line during the double season in 1970 / 71 拉德福德因为在1970 / 1971夺得双冠王赛季中领衔锋线而出名。

We can give different structures on a tensor product h q to make it a bialgebra or hopf algebra . in [ 1 ] radford constructed a hopf algebra a x h with the smash algebra structure and the smash coproduct coalgebra structure , and pointed out that if a bialgebra b has a hopf subalgebra h and a projection ! : b - - > h , then there must be a subalgebra a of b such that b @ a x h is a bialgebra isomorphism 在张量积hq上可以给出不同的构造，使它成为双代数或hopf代数， radford在文献[ 1 ]中构造了以smash积为代数结构，余smash积为余代数结构的hopf代数a h ，并指出若b是双代数， h是b的子hopf代数，且存在投射： b h (即是双代数同态，且| _ h = id _ h ) ，则一定存在b的子代数a ，使ba h是双代数同构。
