Approximation de la diffusion. L’équation de transport peut être résolue dans sa forme originale, mais au prix d’un temps de calcul élevé. La simulation d’un réacteur nucléaire complet est donc généralement effectuée à l’aide du formalisme de la diffusion. Concrètement, l’approximation de la diffusion consiste à éliminer la dépendance angulaire du flux neutronique en effectuant un développement limité du flux neutronique en harmoniques sphériques. 2, record 2, French, - approximation%20de%20la%20diffusion

The element-free Galerkin method is a method which... uses nodal points, but where the use of a connectivity is absent. Displacements and stresses in the material domain are approximated by means of a connectivity-free technique known as moving least squares approximation. This technique requires, besides the nodal data, a set of weight functions and a set of basic functions. Since the growth of crack surfaces can be reflected without changing a connectivity of nodes, it is possible to simulate crack propagation without remeshing. 4, record 3, English, - element%2Dfree%20Galerkin%20method

"orbital theory": The quantum theory of matter applied to the nature and behavior of the electron, either in single atoms (atomic orbital) or in united atoms (molecular orbital). ... In simple language, the orbital theory considers the electron not as a particle, but as a three-dimensional wave that can exist at several energy levels; its exact location and position in the "shell" (which in most elements is a group of orbitals) cannot be precisely determined, but only predicted by the laws of mathematical probability. The orbital levels and the movement of electrons within them are expressed by wave functions and quantum numbers. The probability that an electron will be found in a given volume (i.e., the square of the one-electron wave function) is called the orbital of that electron, and the shape of the orbital is defined by surfaces of constant probability (i.e. spheres and doughnut-shaped ellipses). The electron orbital, described in terms of probability, is like a cloud, with indefinite boundaries. 2, record 8, English, - orbital
