Fr.: regression linéaire
In statistics, a regression method that establishes a linear relationship between two random variables.
Fr.: taille linéaire
The real, physical size, as opposed to angular size.
The property, condition, or state of being linear.
A process of reduction to linear form by appropriate change of variables or by approximation.
Verbal noun of → linearize.
To make linear; give linear form to.
linearized differential equation
hamugeš-e degarsâneyi-ye xatti
Fr.: équation différentielle linéarisée
A differential equation that has been derived from an original nonlinear equation.
In a manner characterized by first-degree algebraic terms.
Adverb of → linear.
Fr.: linéairement dépendant
A set of objects x1, x2, ..., xn (→ vectors, → matrices, → polynomials, etc.) on a given set if there is a linear combination of them: a1x1 + a2x2 + ... + anxn, which is zero, but at least one of the coefficients is non-zero. For example the binomials (2x + y) and (6x + 3y) are linearly dependent, since 3(2x + y) - (6x + 3y) = 0.
Fr.: linéairement indépendant
1) A set of objects x1, x2, ..., xn
(→ vectors, → matrices,
→ polynomials, etc.) if it si not
→ linearly dependent.
linearly polarized light
nur-e qotbide-ye xatti
Fr.: lumière polarisée linéairement
Light exhibiting → linear polarization.
A type of galactic nucleus that is defined by its spectral line emission. The lines are very weak, the most prominent ones being from low ionization states (such as [O II], [N II], [S II] and [OI]). There is so far no generally accepted interpretation of the spectra of liners. It is likely that galaxies of different histories may have their nuclei with liner-type spectra. → retired galaxy.
Short for → Low-Ionization Nuclear Emission-line Region. The term liner was first introduced by T. M. Heckman (1980, A&A 87, 152).
xatt-pahnâ (#), pahnâ-ye xatt (#)
Fr.: largeur de raie
1) The range of frequencies or wavelengths over which
radiations are absorbed or emitted in a transition between a specific
pair of atomic energy levels. The full width is determined between
half-power points of the line.
Fr.: variable linguistique

1) General: An act or mode of linking; the fact of being linked.
From → link + -age a suffix of abstract nouns from O.Fr.
Fr.: théorème de Liouville
A key theorem in statistical mechanics of classical systems which states that the motion of phase-space points defined by Hamilton's equations conserves phase-space volume.
After Joseph Liouville (1809-1882), a French mathematician; → theorem.
1) The act or process of liquefying or making liquid.
1) To reduce to a liquid state.
âvé, âbgun (#)
The state of matter in which a substance exhibits a characteristic readiness to flow, little or no tendency to disperse, and relatively high incompressibility.
O.Fr. liquide, from L. liquidus "fluid, liquid, moist," from liquere "be fluid," related to liqui "to melt, flow."
