释义 | Mien. Physics. attributive and in the genitive. Designating concepts and phenomena described by Mie or arising from his work, esp. in relation to the scattering of light; Mie scattering n. the scattering of light by particles whose size is comparable to the wavelength of the light; cf. Rayleigh scattering n. at Rayleigh n.1 5a. Mie theory n. (also Mie's theory) the theory of Mie scattering. ΚΠ 1943 V. K. La Mer Progress Rep. on ‘Verification of Mie Theory’ (U.S. Office Sci. Res. & Devel. National Def. Res. Comm., Div. 10, OSRD 1857) 1 In the analysis of smokes and fogs the eptical method based on the Mie ‘theory of scattering’ has been found most useful. 1947 Math. Tables & Other Aids Computation 2 226 To illustrate the need for numerical differentiation, suffice it to mention the evaluation of the derivatives of the spherical scattering functions in the Mie theory. 1957 H. C. Van de Hulst Light Scattering Small Particles 452 A curious application of the Mie theory..is the computation of the thermal radiation by the interstellar grains. 1967 Ecol. Monogr. 37 291/1 Within the tissues the dominant scattering effects are due to the melanin granules, guanine crystals, and red blood cells because of their large size with respect to the wavelength (Mie scattering). 1974 Physics Bull. Jan. 11/2 If a laser beam is emitted into the atmosphere, some of the radiation will be absorbed by atmospheric molecules, some will be scattered by them (Rayleigh scattering) and some will be scattered by aerosols (Mie scattering). 1988 Nature 17 Nov. 227/1 I have used the discrete dipole approximation..to compare the ultraviolet extinction of these ‘Kroto-spheres’ with the usual Mie model. 1999 Biophysical Jrnl. 76 1080 Both methods rely on Stokes' equations to estimate particle size and density, whereas turbidity, corrected using Mie's theory, provides the concentration measurement. This is a new entry (OED Third Edition, March 2002; most recently modified version published online March 2022). < n.1943 |
