heterogeneous materials的用法和样例：
例句
- In heterogeneous anisotropic materials the heat flow vector and conductivity are more complex.
在各向异性的非均质材料中，热流向量和热导率很复杂。 - Although the theoretical model about the buckle of homogeneous isotropic materials has been established, few have concerned about anisotropic materials, which are more realistic.
而接续前人的研究，虽在一般均质材料之拱弯褶皱理论上已有相当基础，对于更接近实际地质材料的非等向性材料却较少著墨。
