It was shown that with the help of vectrix one can treat the relative derivatives of a tensor more clearly and more rigorously when multiple reference frames were concerned.

研究表明，通过借助于矢阵概念，在涉及多个坐标系时，张量的相对导数得到了更加清晰和严格地描述。

To characterize relative orientation between the loading direction and material fabric, an anisotropic variable expressed by the joint invariants of the stress tensor and fabric tensor is introduced.

为了描述材料的各向异性，引入了一个由应力张量和组构张量的联合不变量表达的各向异性参数。
