The inversemapping is achieved through BP network, and neural network modul is constructed for designing process parameters.
通过误差逆传播(BP)网络实现了逆映射，建立了工艺参数设计的神经网络模块。

There is no explicit formulation of inversemapping about the isoparametric element, so inversemapping is avoided in finite element analysis.
由于等参元不存在逆变换的显式，所以在有限元分析的列式中都回避等参元逆变换。

Based on the new method, the paper discusses an inversemapping of rational parameter surface, also, the implicit equation of the parametric equation is obtained.
