不适定问题研究的若干进展

摘要

对不适定问题的严密定义、数学模型、求解方法及其各方面应用作了系统的介绍，着重论述了传热反问题的几种数学表述及其近5a来的相关发展，较详细列举了不适定问题求解的几种主要算法，并介绍了新近出现的一些计算思路及模式，最后探讨了结合并行计算完善与改造已有算法的可能性.%This paper presents the definition of ill-posed problem and its applications.For an important case,the inverse heat conduction problem,it introduces some alogrithms of ill-posed problems,analyzes their advances and points out that these algorithms will be improved by cooperating with the parallel calcultion.
