With the object exchange model (OEM) as the intermediate model, the view mechanism is discussed based on the layer relation model.

以对象交换模型作为中间模型，讨论了基于层次关系模型的视图机制，提出了一个增量维护的算法。

Then, by the function expansion, the nonlinear transfer function of this model was converted to intermediate model which is linear one and can be identified using support vector regression (SVR).

再利用函数展开将模型的非线性传递函数转换为等价的线性中间模型，并通过SVR求取中间模型参数。
