isotropous
/,aisou'trɔpik/ Cách viết khác : (isotropous) /ai'sɔtrəpəs/
Definition
Adjective 1. Having the same physical properties in all directions: A material or substance is described as "isotropous" when its characteristics, such as elasticity, thermal conductivity, or refractive index, are identical regardless of the direction in which they are measured. This is the opposite of "anisotropic."
Usage
The word "isotropous" is a technical term used primarily in physics, materials science, and engineering. It describes the uniformity of a material's properties. It is synonymous with "isotropic," which is the more common form.
Examples
- In Physics: "A perfect gas is considered an isotropous medium because its pressure and temperature are uniform in all directions."
- In Materials Science: "Glass is often used as an example of an isotropous material because it transmits light equally in every direction."
- In Geology: "The rock formation was found to be isotropous, meaning seismic waves traveled through it at a constant speed regardless of their path."
Advanced Usage
- Scientific Modeling: In theoretical models, a medium is often assumed to be isotropous to simplify calculations, even if real-world materials have slight directional variations.
- Comparative Analysis: The term is frequently used in contrast to "anisotropic." For example: "The crystal's optical properties are anisotropic, unlike the isotropous properties of the surrounding glass."
Variants and Related Words
- Isotropic (adj.): This is the far more common and preferred variant of "isotropous." They are fully interchangeable in meaning.
- Example: "Isotropic materials simplify the design of optical lenses."
- Isotropy (n.): The noun form describing the state or quality of being isotropic/isotropous.
- Example: "The isotropy of the material was confirmed through rigorous testing."
- Anisotropic (adj.): The direct antonym, meaning having properties that vary with direction.
- Example: "Wood is anisotropic; it is stronger along the grain than across it."
Synonyms
- Uniform (in a directional context)
- Non-directional
- Omnidirectional (often used for radiation or signal propagation)
Antonyms
- Anisotropic
- Directional
- Non-uniform
Adjective
-
invariant with respect to direction
