point symmetry उदाहरण वाक्य
उदाहरण वाक्य
- Such a phase transition typically results in only a small deviation from the nonferroic crystal structure, but in altering the shape of the unit cell the point symmetry of the material is reduced.
- There are four involutional groups : no symmetry ( C 1 ), reflection symmetry ( C s ), 2-fold rotational symmetry ( C 2 ), and central point symmetry ( C i ).
- Point symmetry allows the plane to be filled by growing kites, with the topology as a square tiling, V4.4 . 4.4, and can be created by crossing string of a dream catcher.
- It is also unique among the Platonic solids in having faces with an even number of sides and, consequently, it is the only member of that group that is a zonohedron ( every face has point symmetry ).
- Ferromagnets is a term that most people are familiar with, and, as with ferroelastics, the spontaneous magnetization of a ferromagnet can be attributed to a breaking of point symmetry in switching from the paramagnetic to the ferromagnetic phase.
- Computational geometry takes a broader view on this issue and concluded already in 1991 that the problem of testing approximate point symmetries in noisy images is in general NP-hard and later on that it is also NP-complete.
- Free Re 2 ( CO ) 10 ( point symmetry D 4d ) has a CO stretch representation of 2A 1 + E 2 + E 3 + 2B 2 + E 1, where 2B 2 + E 1 are IR active.
- In this paragraph, we consider precisely " expanded Lie point symmetries " i . e . we work in an expanded space meaning that the distinction between independent variable, state variables and parameters are avoided as much as possible.
- He documented this philosophy in " The Psychological Approach to Photographic Design, " his associate thesis for the ASP, and in a self-published booklet describing what he called crash-point symmetry, a compositional technique still widely used by professional photographers.
- These notions are merely special cases of Sophus Lie's notion of the point symmetry of a differential equation ( or system of equations ), and as Lie showed, this can provide an avenue of attack upon any differential equation which has a nontrivial symmetry group.
