由多孔固体的吸附等温线计算孔径和吸附能分布的著名吸附积分方程式(AIE)从数学的角度来看是第一类线性Fredholm型积分方程式,因此是一个不适定的问题。通过正则化来解决这样一个不适定的问题,我们能现实地期待什么呢?通过所谓的dansatz方法限制可能的解决方案的数量有意义吗?本文从无到有地阐述了两种解决不适定问题的方法,并用具体的例子加以说明。讨论了它们的相关性和基本限制。
The well-known adsorption integral equation (AIE) for calculating pore size and adsorption energy distributions from adsorption isotherms on porous solids is, from the mathematical point of view, a linear Fredholm integral equation of the first kind and therefore an ill-posed problem. What can we realistically expect from the solution of such an ill-posed problem byregularization? Does it make sense to restrict the number of possible solutions by the so-calledansatz method? In this paper, the two methods for solving ill-posed problems are from scratch explained and illuminated by concrete examples. Their relevance and fundamental limitations are discussed.
