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.

在此参数表示下，模糊数可直接视为二维度量空间r 2中的有界连续曲线，这给分析模糊微分方程带来了便利。

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。
