由实结合代数的双环讨论p＋q维Minkowski空间Rp,q生成的Clifford代数Clp,q的性质.结果表明：所有非可除的Clp,q均存在双环为其子代数;所有中心子代数非可除的Clp,q均为双环.

英文摘要：

On the basis of double ring of real associative algebra,the properties of Clifford algebra Clp,q which generated by Minkowski space Rp,q were discussed,which indicates that all the non divisible Clp,q has a double ring as its subalgebra and all the Clp,q with center subalgebra non divisible is a double ring.
