By the parametric representation, fuzzy number means a bounded continuous curve in the two-dimensional metric space R2, so that it is easy to analyze fuzzy differential equations.
This representation relies only on the displacement components of the mid_plane, which are governed by a set of two_dimensional differential equations similar to those in the classical plate theory.
这一表达式仅依赖于中面的位移分量，后者由一组类似于经典板理论的二维微分方程控制。

The differential Jones vector equation is derived, then the representation theory of differential Jones-matrix is introduced.
