英文摘要	We use the preconditioned conjugate gradient (PCG) method to analyze the symmetric positive-definite Toeplitz systems. Then we present a new embedding constructing preconditioner way and prove that many other ways of constructing preconditioners are generally the special cases of this method. We propose the omega-circulant boundary condition and make comparison with both the ordinary circulant boundary condition and helix one. Furthermore, we obtain a new type of boundary condition: the mixed boundary condition.
