Discrete Poisson equation — In mathematics, the discrete Poisson equation is the finite difference analog of the Poisson equation. In it, the discrete Laplace operator takes the place of the Laplace operator. The discrete Poisson equation is frequently used in numerical… … Wikipedia
Burgers' equation — is a fundamental partial differential equation from fluid mechanics. It occurs in various areas of applied mathematics, such as modeling of gas dynamics and traffic flow. It is named for Johannes Martinus Burgers (1895 1981).For a given velocity… … Wikipedia
Young–Laplace equation — In physics, the Young ndash;Laplace equation is a nonlinear partial differential equation that describes the capillary pressure difference sustained across the interface between two static fluids, such as water and air, due to the phenomenon of… … Wikipedia
Dielectric — A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material, as in a conductor, but only slightly shift from their … Wikipedia
Debye relaxation — is the dielectric relaxation response of an ideal, noninteracting population of dipoles to an alternating external electric field. It is usually expressed in the complex permittivity varepsilon of a medium as a function of the field s frequency… … Wikipedia
DIÉLECTRIQUES — Le mot «diélectrique» s’emploie en général comme adjectif, pour qualifier une substance qui peut emmagasiner de l’énergie électrostatique, c’est à dire une substance à laquelle on peut appliquer un champ électrique élevé et sur laquelle on peut… … Encyclopédie Universelle
