Definition of isotropic in English: isotropicadjective ˌʌɪsə(ʊ)ˈtrɒpɪk Physics 1(of an object or substance) having a physical property which has the same value when measured in different directions. 〔物理〕（物体或物质）各向同性的。常与ANISOTROPIC 相对 Often contrasted with anisotropic Example sentencesExamples - In isotropic ethanol solutions efficient intersystem crossing is observed with quantum yields around 0.5 being reported.
- In thin section, however, it is a brilliant green, isotropic mineral.
- For a purely linearly isotropic material, a single constant suffices to describe the sample elasticity.
- In a homogeneous and mechanically isotropic medium, two types of body waves are generated.
- Because the bonds are not symmetrical, glass is isotropic and has no definite melting point.
- Thus, equations for isotropic mixtures of phase domains are not applicable.
- 1.1 (of a property or phenomenon) not varying in magnitude according to the direction of measurement.
（特性或现象）同向性的 Example sentencesExamples - Germination of wild-type spores is initiated by an isotropic growth phase generating spherical germ cells.
- In isotropic spreading, retraction of [alpha] actinin is limited until cells are over half spread.
- The system was simulated at constant isotropic pressure of 1 atm applied independently to each box dimension.
- At the bulging stage, the site of primordium initiation shows an intensified expansion that is nearly isotropic.
- Interestingly, several isotropic fluorescence times were found to coexist, indicating structural heterogeneity of the DNA.
Derivativesadverb Physics The buttress surface is expanding with high areal strain rates and nearly isotropically. Example sentencesExamples - Nitric oxide crosses cell membranes without mediation of channels or receptors-it diffuses across cellular membranes isotropically.
- The fractal shape and rounding of DPTAP domains indicate that domain growth occurred relatively isotropically.
- This implies that the acyl chains are more isotropically distributed and that the estimate of S is an upper limit.
- Therefore, in order to describe accurately the soil behavior, an anisotropic model is still necessary to be incorporated even if the soil is initially isotropically consolidated.
nounʌɪˈsɒtrəpiaɪˈsɑtrəpi Physics To quantitatively ascertain the isotropy of the collagen gels imaged with confocal reflectance microscopy, several approaches are used. Example sentencesExamples - Their circular shape, optical isotropy, and rapid reconfiguration all indicate a fluid structure.
- And so the isotropy of the radiation from the Big Bang would no longer be inconsistent with the finiteness of the speed of light.
- Errors introduced by the assumption of hemispheric isotropy are estimated to be less than 4%.
- All gel concentrations have a fairly flat distribution, again emphasizing the isotropy of these gels within the plane in the absence of cells.
- Nevertheless, homogeneity and isotropy came to be jointly codified as the ‘cosmological principle.’
