1a) A → discussion, as of a public question in an
assembly, involving opposing viewpoints.

To substract the → bias from a flat-field or science frame obtained using an electronic detector.
Fr.: soustraction du biais
Verbal noun of → debias.
Fr.: séparer les composantes
Fr.: séparation des composantes
The process or state of separating or resolving into constituent → spectral lines.

Verbal noun of → deblur.
From Fr. débris, from M.Fr. débriser "break down, crush," from O.Fr. debrisier, → de- + brisier "to break," from L.L. brisare.
Tifâl, from tif "rubbish, sweepings, debris" + -al relation suffix → -al.
Fr.: disque de débris
A disk developing around a star after the dissipation of the → protoplanetary disk of gas and dust whose material was used in the formation of planets during the first 10 million years. The resulting debris disk is mainly composed of residual → planetesimals analogous to → asteroids, → comets, and → Kuiper Belt Objects in the Solar System. Their mutual collisions produce observable → dust emission in a belt encompassing the planetary system.
After Peter Joseph Wilhelm Debye (1884-1966), Dutch-born American, who made important studies in the conductivity of electricity by salt solutions and in the heat capacity of solids. He received the 1936 Nobel Prize in chemistry for his work on the structure of molecules.
qânun-e Debye (#)
Fr.: loi de Debye
derâzâ-ye Debye (#)
Fr.: longueur de Debye
A characteristic length scale in a → plasma, determined by the temperature and number density of the charged particles. The Debye length (in cm) is given by the expression: λD = 743(Te/ne)1/2, where Te is the electron temperature in → electron-volts and ne is the electron density in cm-3. Particles which pass each other at distances smaller than the Debye length interact directly. Outside the Debye length particle interactions are dominated by collective effects. In typical laboratory plasmas the Debye length is small compared with the plasma dimension, so that collective effects are important.
model-e Debye (#)
Fr.: modèle de Debye
An extension of the → Einstein model accounting for → specific heats, based on the concept of → elastic waves in → crystals. In this model specific heat is given by: CV = 9R[(4/x2)∫ y2/(ey - 1)dy - x/(ex - 1)], integrating from 0 to x, where R is the → gas constant, k is → Boltzmann's constant, x = hνmax/k, and y = hν/k. The parameter TD = hνmax/k is the characteristic → Debye temperature of the crystal. At low temperatures the specific heat prediction by this model is in good agreement with observations (→ Debye law), in contrast to Einstein's model.
damâ-ye Debye (#)
Fr.: température de Debye
Prefix meaning "ten" and "ten times" used in terms belonging to the metric system.
From Fr. déca-, from L. deca-, dec-, from Gk. deka "ten;" cf. Av. dasa "ten," Mod.Pers. dah "ten," Skt. dasa, PIE *dekm (Dan. ti, Du. tien, Ger. zehn, E. ten, Fr. dix).
Dekâ-, from Fr. as above.
