摘要：
In this paper, we consider the inverse problem of determining the heat source, which depends only on spatial variable in one-dimensional heat equation in a bounded domain where data is given at some fixed time. A conditional stability result is given, and a quasi-boundary value regularization method is also provided. For this regularization solution, the Holder type stability estimate between the regularization solution and the exact solution is obtained. Numerical examples show that the regularization method is effective and stable. Copyright (c) 2013 John Wiley & Sons, Ltd.
