Lattice constant - Wikipedia, the free encyclopedia The lattice constant, or lattice parameter, refers to the physical dimension of unit cells in a crystal lattice. Lattices in three dimensions generally have three lattice constants, referred to as a, b, and c. However, in the special case of cubic crystal
lattice hypothesis - definition of lattice hypothesis by Medical dictionary hypothesis /hy·poth·e·sis/ (hi-poth´ĕ-sis) a supposition that appears to explain a group of phenomena and is advanced as a basis for further investigation. alternative hypothesis one that is compared with the null hypothesis in a statistical test. biogeni
Lattice parameter | Define Lattice parameter at Dictionary.com a parameter, either a measure of length or angle, that defines the size and shape of the unit cell of a crystal lattice.

Classics in materials science: Vegard’s law of linear relationship between lattice parameter and all Let us consider a pure metal, say copper; let us consider the case in which we remove some copper atoms and substitute for them with gold atoms; since gold atoms are slightly bigger than copper atoms, it is natural to expect that the lattice parameter in
Lattice Boltzmann methods - Wikipedia, the free encyclopedia Lattice Boltzmann methods (LBM) (or Thermal Lattice Boltzmann methods (TLBM)) is a class of computational fluid dynamics (CFD) methods for fluid simulation. Instead of solving the Navier–Stokes equations, the discrete Boltzmann equation is solved to simul

lattice command - LAMMPS Molecular Dynamics Simulator A lattice of style none does not define a unit cell and basis set, so it cannot be used with the create_atoms command. However it does define a lattice spacing via the specified scale parameter. As explained above the lattice spacings in x,y,z can be used
