The debye (symbol: D) (/ d ɛ ˈ b aɪ /; Dutch: [dəˈbɛiə]) is a CGS unit (a non-SI metric unit) of electric dipole moment named in honour of the physicist Peter J. W. Debye.It is defined as 1 × 10 −18 statcoulomb-centimeters. Historically the debye was defined as the dipole moment resulting from two charges of opposite sign but an equal magnitude of 10 −10 statcoulomb (generally ...

In the Debye–Hückel approximation, we maintain the system in thermodynamic equilibrium, at a temperature T high enough that the fluid particles obey Maxwell–Boltzmann statistics.At each point in space, the density of electrons with energy j has the form = () ⁡ [()]where k B is Boltzmann's constant.Perturbing in φ and expanding the exponential to first order, we obtain

La capacité thermique massique (symbole usuel c), anciennement appelée chaleur massique ou chaleur spécifique [a], [1], [2], est la capacité thermique d'un matériau rapportée à sa masse. C'est une grandeur qui reflète la capacité d'un matériau à accumuler de l'énergie sous forme thermique, pour une masse donnée, quand sa température augmente. . Une grande capacité …

In thermodynamics and solid-state physics, the Debye model is a method developed by Peter Debye in 1912 for estimating the phonon contribution to the specific heat (Heat capacity) in a solid. It treats the vibrations of the atomic lattice (heat) as phonons in a box, in contrast to the Einstein photoelectron model, which treats the solid as many individual, non-interacting …

An intermolecular force (IMF) (or secondary force) is the force that mediates interaction between molecules, including the electromagnetic forces of attraction or repulsion which act between atoms and other types of neighbouring particles, e.g. atoms or ions.Intermolecular forces are weak relative to intramolecular forces – the forces which hold a molecule together.

I-V characteristic of the Debye sheath. The beginning of Langmuir probe theory is the I–V characteristic of the Debye sheath, that is, the current density flowing to a surface in a plasma as a function of the voltage drop across the sheath.The analysis presented here indicates how the electron temperature, electron density, and plasma potential can be derived from the I–V …

결합 쌍극자 모멘트(bond dipole moment)는 화학에서 전기 쌍극자 모멘트의 개념을 사용해 분자 내 화학결합의 극성의 정도를 나타내는 척도이다. 분자의 이온성과 전기음성도차를 측정하는 데 유용하다. 화학에서 쓸 때는 간단히 쌍극자 모멘트(dipole moment)라 부르기도 한다.

The Mie solution to Maxwell's equations (also known as the Lorenz–Mie solution, the Lorenz–Mie–Debye solution or Mie scattering) describes the scattering of an electromagnetic plane wave by a homogeneous sphere.The solution takes the form of an infinite series of spherical multipole partial waves.It is named after Gustav Mie.. The term Mie solution is also …

Monitorul este un dispozitiv periferic de ieșire pentru afișare grafică luminoasă de date și imagini, folosit uzual în instalații de telecomunicație și în tehnica prelucrării datelor. Datele sunt reprezentate prin caractere și simboluri. Din punct de vedere constructiv, monitoarele erau la origine televizoare fără partea de recepție a semnalelor TV.

The Debye sheath (also electrostatic sheath) is a layer in a plasma which has a greater density of positive ions, and hence an overall excess positive charge, that balances an opposite negative charge on the surface of a material with which it is in contact. The thickness of such a layer is several Debye lengths thick, a value whose size depends on various characteristics of plasma …
