In this paper,the uniform boundedness and uniform ultimate boundedness of the stochastic retarded differential equations is investigated.The new Razumikhin theorems of boundedness about these systems are obtained by using the Lyapunove functions and Razumikhin technique.It should be noted that the boundedness criteria prove the global existence of solutions as well as boundedness,thus the available results in references are improved.Finally,an example is illustrated to verify the theorems.
