“anisotropic”的概念、定义、翻译、参考文献-科学参考

anisotropic

Physics

Denoting a medium in which certain physical properties are different in different directions. Wood, for instance, is an anisotropic material: its strength along the grain differs from that perpendicular to the grain. Single crystals that are not cubic are anisotropic with respect to some physical properties, such as the transmission of electromagnetic radiation. Compare isotropic.

Statistics

See isotropy.

Chemistry

Single crystals that are not cubic are anisotropic with respect to some physical properties, such as the transmission of electromagnetic radiation. Compare isotropic.

Electronics and Electrical Engineering

1. Denoting crystalline material whose properties, including conductivity, permittivity, and permeability, vary with direction relative to the crystal axes as a result of the crystal structure.
2. More generally, denoting any material or process, such as etching, whose properties are nonuniform with direction.

Geology and Earth Sciences

1. Applied to substances whose optical or other physical properties vary according to the direction from which they are observed. In optical mineralogy the term is applied to minerals other than cubic that split the light passing through them into two vibration directions, each with a different velocity (provided the light is not travelling along an optic axis), as a result of the light being doubly refracted (see double refraction). In addition, each beam is refracted differently for different colours of light.
2. In engineering geology, anisotropy refers to a rock whose engineering properties vary with direction. For example, schist, a highly anisotropic rock, has a compressive strength that varies depending upon the orientation of the foliation to the applied load (see compressive stress).
