inhomogeneous, a.|ˌɪnhɒməʊˈdʒiːnɪəs|
[in-3.]
Not homogeneous. a. Not of uniform nature throughout; composed of diverse constituents; heterogeneous.
1904Jrnl. Physical Chem. VIII. 425 The 58·5 percent alloy is homogeneous when annealed at 720° and quenched. It becomes inhomogeneous..if annealed at 685° and quenched. 1938R. W. Lawson tr. Hevesy & Paneth's Man. Radioactivity (ed. 2) ii. 34 At the moment of their emission the α-rays from a single radioactive substance all possess the same velocity... As soon as they have traversed a sheet of an absorbing substance, however,..the pencil of rays begins to be inhomogeneous. 1956Nature 25 Feb. 380/2 The relatively great variations are due partly to the inhomogeneous microstructure of the muscular tissue. 1962Corson & Lorrain Introd. Electromagn. Fields xi. 400 We shall not attempt here a rigorous discussion of wave propagation in such inhomogeneous media.
b. Math. Consisting of terms that are not all of the same degree or dimensions.
1943Margenau & Murphy Math. Physics & Chem. vii. 237 One remarkable feature of an inhomogeneous equation..is that it may not possess solutions for every value of k even though the homogeneous equation, with the same boundary condition, has solutions. 1946L. Brillouin Wave Propagation vi. 109 This is an inhomogeneous differential equation as it stands. 1957L. Fox Numerical Solution Two-Point Boundary Probl. viii. 266 In §5 we solved the approximate finite-difference form of this problem by considering two trial solutions, y(1) and y(2), of which the former satisfied the inhomogeneous finite-difference equations and the correct initial condition, and y(2) satisfied the homogeneous forms..and had initial value zero. 1962W. B. Thompson Introd. Plasma Physics iv. 57 Of the two possible choices for pressure, the first leads to slightly simpler results, although it does make eq. (4.5.8) inhomogeneous.
Hence ˌinhomoˈgeneously adv., in an inhomogeneous manner; unevenly, irregularly.
1909in Webster. 1937Q. Jrnl. Geol. Soc. XCIII. 582 A monomict, inhomogeneously, orientated, heteroaxial quartz-B-tectonite with partial recrystallization. 1966D. G. Brandon Mod. Techniques Metallogr. i. 4 The difficulty comes when the features of interest are too small to be resolved at a low magnification and too widely or inhomogeneously dispersed to include a representative area..at a high magnification. 1973Sci. Amer. Dec. 70/3 Owing to the random distribution of impurity ions..the energy levels are inhomogeneously broadened over the volume of the medium. |
