摘　　要：讨论了抛物系统初边值问题的参数识别问题 .通过引入罚函数 。In this paper, we consider identifications of physical parameters in parabolic initial boundary value problems. The identification problem is formulated as a constrainted minimization problem by using the output least squares approach with the H 1 regulatization. By introducing a penalty function, we construct a sequence of unconstrained minimization problems to approximate the constrainted minimzation problem.
