通过引入最佳平均逼近直线，分别从几何直观和极限情形两个角度，研究了有限离散函数的导数概念的表现。

Design parameter based on finite element model updating is part of an inverse problem of structure dynamics. Features of the structure are used as a function of design parameters. Parameters are updated based on the first derivative. This paper presents a new method which treats the model updating as a positive problem.
