晶体结构;带有基元的晶格(Crystal Structure;Lattice with a Basis) 回到物理,对于一个实际的晶体,我们可以用一个布拉维格子以及原胞中各种粒子的组分来描述它。当讨论到抽象的布拉维格子和实际的晶体的区别是,我们会用到术语“晶体结构(crystal Structure)”。一个晶体结构可以看作是一个全同的物理单元复制了许多份,...
The most common crystal structure with the SC lattice is the CsCl structure. In this structure the basis consists of two atoms (one molecule of CsCl) with Cs at(0,0,0)and Cl ata(1/2,1/2,1/2)(or vice versa), where a is the cubic lattice constant. This structure is shown in fol...
crystal latticeBravais latticeThe local-equilibrium statistical ensemble is constructed which describes the thermodynamics of a Bravais lattice taking into account the effects of nonlocality. Correlation-function expressions are obtained for the nonlocal isothermal and adiabatic elastic constants and other ...
Crystal lattice: a unit cell based on a, b, c vectors and the crystal build-up. A crystal can be characterized both by the unit cell (the carrier of the chemical composition and atomic structure), and by three translation vectors a, b and c; the latter can be used to build the ...

材料专业英语——1.Classifaction of materials Crystal and amorphous Classification of materials Solid materials have been conveniently grouped into three basic classifications: metals, ceramics, and polymers. This scheme is based primarily on chemical makeup and atomic structure, and most materials fall ...
The crystal structure of a new metastable form of tellurium dioxide, γ-TeO2 (orthorhombic, P212121 (no. 18); a=4.898 A, b=8.576 A, c=4.351 A; Z=4) was solved ab initio and refined to RB=0.0387 and Rp=0.115, on the basis of a Rietveld analysis of its powder...
Peter and H.D. Lutz 摘要: The crystal structure of Ca(IO3)2·6H2O (Fdd2, Z = 8, a = 1485.9(1) pm, b = 2301.8(2) pm, and c = 639.44(5) pm, RW = 4.7%) has been refined by single-crystal neutron diffraction studies on the basis of 1150 reflections using the Becker and ...
The other six systems, in order of decreasing symmetry, are hexagonal, tetragonal, trigonal (also known as rhombohedral), orthorhombic, monoclinic and triclinic.Bravais lattice is a set of points constructed by translating a single point in discrete steps by a set of basis vectors. In 1848, ...
