In this thesis, the axis rotation symmetry of third-order nonlinear elasticity was researched with the help of grouptheoretical methods.
本文用群论的方法研究了三阶非线性弹性的轴转动对称性。

We should notice that not any grouptheoretical knowledge is introduced in the deduce process for obtaining these theoretical results and transformations.
值得注意的是,一阶情形与高阶情形的理论结果的推导与变换的计算无须用到任何的群论知识。
