A theoretical description of the deformed state of QCs requires a combined consideration of interrelated phonon and phason field. The phonon field describes the motion of lattices in physical space, while the phason field describes the quasiperiodic arrangement of atoms in the complementary orthogonal space, which interact with one another. Owing to the existence of phason field, the elasticity of QCs is more complex than that of the conventional crystals.

准晶弹性的刻画不仅需要描写晶格振动的声子场，还需要刻画原子准周期排列的相位子场，而且二者是相互耦合的，所以准晶的弹性较经典的一般晶体的弹性复杂的多。

Additionally, there was new AES that may be a transition form of hybridism of carbon atom. It is concluded that carbon atom of graphite changes from sp^2 π to sp^3 through "metal catalyst layer", and deposits on the surface of diamond.

According to these results, it is considered that in the matrix of gray cast iron nitrogen solid-solubilizes as interstitial atom in the octahedron interstice of ferrite and cementite which is not occupied by carbon atom, and causes the crystal lattice of ferrite and cementite to distort, so that the micro-hardness of the matrix increases.

依据这一实验结果，作者认为，在灰铸铁基体组织中，氮以间隙原子的方式固溶在铁素体和渗碳体中未被碳原子占据的八面体间隙里，造成铁素体和渗碳体晶格畸变，从而提高了基体组织的显微硬度。

Using the modified analytical embedded atom method, the physical properties of D03 type Fe3Al alloy, including the lattice constant, formation heat, elastic constants, phonon dispersion curves, density of states, molar heat capacity at constant volume, Debye temperature and thermal expansion, were calculated.

The element Sb exists in many forms in the film: transpositional atoms and compounds such as Sb2O3, Zn7Sb2O14 etc. ZnO crysal grains grow in mixing directions. The lattice relaxation and content of second phases increase when more Sb is doped. The UVA absorption of doped ZnO thin film obviously increases. The ultraviolet absorption peak narrows, the absorption intensity increases, the absorption margin becomes steep and moves to shorter wavelength about 5 nm, and the visible absorption increases in some sort.

薄膜中Sb以多种形态存在：替位原子和化合物(Sb2O3、Zn7Sb2O14)等，ZnO呈混晶方式生长；随着Sb含量的增加，其引起的晶格畸变和次晶相的含量逐渐增加；掺杂薄膜在远紫外波段的吸收显著增强，UV吸收峰变窄，强度增大，吸收边变得陡峭且向短波方向移动达5nm，在Vis波段的吸收有所增强。

A layer of tin atoms on a germanium surface forms a flat lattice, but at temperatures below about 150 Kelvin--for reasons that aren't entirely clear--the tin layer spontaneously corrugates to form a new structure, or phase, with one atom out of every three moving away from the substrate.

一层锡原子在锗表面可以形成一个平整的晶格，但是当温度低于150K锡原子层会自发的褶皱起来形成一种新的结构，或者说是新相，这时每三个原子中会有一个运动而离开基质表面。
