The appendage is modelled as a finitedeflection beam having linear constitutive equations.
假设附件为有限变形梁，但其本构方程是线性的。

According to the finitedeflection theory, it was assayed qualitatively that the honeycomb floor which was designed base on this theory has large safety reserve.
结合大挠度理论，定性地分析了按上述方法设计的蜂巢芯楼盖具有较大的安全储备。
