In this paper, the Cauchy problem for the homogeneous and nonhomogeneous Laplace equation in a strip domain is discussed. Where the Cauchy data atis given, and the solution is found in the interval (0,1). The corresponding error estimation is obtained by a new quasi-reversibility regularization method with a appropriate regularization parameter selection.
