摘要
主要介绍一种以静态、线弹性模型为基础，采用迭代思想，通过分析灵敏度矩阵反算结构层模量的方法，并用数学优化方法对其进行改进。
In this paper,one method based on the static linearelastic model is mainly introduced to backcalculate the moduli of structural layers by using the iterative calculation and through analysing the sensitivity matrix;in addition,improvement of the method has been made by mathematical optimization
