例句與造句

1. Starting with the discrete Lattice Boltzmann equation ( also referred to as LBGK equation due to the collision operator used ).
2. And without the discrete lattice assumption, the above construction not only fails to reach a contradiction, but produces a ( non-discrete ) counterexample.
3. A necessary condition for the existence of breathers in discrete lattices is that the breather main frequency and all its multipliers are located outside of the phonon spectrum of the lattice.
4. The strength of the theorem is that " not all " finite groups are compatible with a discrete lattice; in any dimension, we will have only a finite number of compatible groups.
5. Penrose tilings may have 5-fold rotational symmetry and a discrete lattice, and any local neighborhood of the tiling is repeated infinitely many times, but there is no linear translation for the tiling as a whole.
6. It's difficult to find discrete lattice in a sentence. 用discrete lattice造句挺難的
7. In order to see what happens when two particles are at exactly the same point, it is mathematically simplest either to make space into a discrete lattice, or to Fourier transform the field in a finite volume.
8. In practice, most of the interesting cases are surfaces with negative curvature, and are thus realized by a discrete lattice \ Gamma in the group \ operatorname { PSL } ( 2, \ mathbb { R } ) acting on the upper half-plane.
9. For example, the pentagon symmetries, D 5, are incompatible with a discrete lattice of translations . ( Each higher dimension also has only a finite number of such crystallographic groups, but the number grows rapidly; for example, 3D has 320 groups and 4D has 4783 .)
10. To evaluate the Fourier transform \ tilde { \ rho } ( \ mathbf { k } ) of the charge density field efficiently, one uses the Fast Fourier transform, which requires that the density field be evaluated on a discrete lattice in space ( that's the "'mesh "'part ).
