摘要：
Let R be an arbitrary 2-torsionfree commutative ring, M(n,R) the matrix algebra consisting of all nn matrices over R, S(n,R) (resp., D(n,R)) the subset of M(n,R) consisting of all symmetric (resp., diagonal) ones. In this article, we first determine all the Jordan subalgebras of S(n,R) containing D(n,R), then for any given Jordan subalgebra of S(n,R) containing D(n,R), we give an explicit description on its Jordan derivations.
