Recently, the study of Si-based low dimensional material physics andtechnology indicated that Si-based optoelectronics will be one of the main topicsin the semiconductor optoelectronics research area in the near future, and Si-basedlow dimensional light-emitting materials are fundamental in semiconductor opto-electronic integration technology.

In this article, it has been reviewed that the recent development and application of zero_, one_ and two_dimensional material in the reaction of PEMFC according to the different dimensional materials.

By using the finite element analysis method,a three dimensional material parametric model is established,and the structure optimization design of a elastic ring of the forcemeasuring platform is completed.

If the magnetic field is strong enough, the number of bound states of D~ centers is countless in three dimensional material, however in two dimensions only four bound states are found.

The increase in the yield strength of the thinner microbeam is attributed to the increase in the strain gradient contribution due to inhomogeneous deformation of the small dimensional material.

Many self-interstitial atoms cluster in cascades to form highly glissile dislocation loops, and, so, contribute to two-dimensional material transport in damage evolution.

In the spray deposition process, the master alloy of AS17 was atomized using N2 gas, and was deposited on a collecting substrate directly into a three-dimensional material.

The theoretical approach involves a full-field reappraisal of the Lamb solution for a surface wave propagating in a homogeneous, isotropic, elastic, two-dimensional material for the cases of plane strain and plane stress.

A low-dimensional material with the composition {(n-C16H33)(CH3)2S}∞+1[CdCl3]- has been prepared.

It has been confirmed by the author that the quality of the antithermal shock stressof non-granulated sintered substance is related with the thermodynamics, mechanics, geo-metry and environment of the material and that of granulated sintered substance is furtherrelated with its grain structure.By mathematical analysis, the coefficient of safety of non-dimensional materials can be expressed as follow: A general method of determining the influence of the geometrical shape of the subs-tance on stress...

It has been confirmed by the author that the quality of the antithermal shock stressof non-granulated sintered substance is related with the thermodynamics, mechanics, geo-metry and environment of the material and that of granulated sintered substance is furtherrelated with its grain structure.By mathematical analysis, the coefficient of safety of non-dimensional materials can be expressed as follow: A general method of determining the influence of the geometrical shape of the subs-tance on stress failure is presented. The method designed to find out, by experiments, thefunctional relationship between radius of curvature R and geometrical factor C_α renderedpossible the calculation of and its use in production by use of the above formula. A theory has been postulated that the vector of thermal shock stress scatters on the bigclinker grains while diffracts on grains of medium size which explains the antithermal shockfunction of the grain structure. Finally, by use of statistical conception and that of finiteelement, a scattering model is discussed thereby calculation is carried to derive the follo-wing formulas for the coefficient of safety of structure ζ and for the coefficient of safetyrefractory material.

In this paper, R. G, Muncaster's zero-dimensional elastic bodies are generalized to general zero-dimensional material bodies of higher order. From classical continuum theroy of non-polar media, we derive out the balance laws and thermodynamics inequality for zero-dimensional material bodies from which all the balance laws and thermodynamic ineqality for micromorphic material bodies are deriven out. By this way, we have established a connection between the theroy of zero-dimensional material...

By this way, we have established a connection between the theroy of zero-dimensional material bodies and the theory of micromorphic material bodies which is similar to that between the mechanics of rigid particles and the classical continuum mechanics of non-polar media.

The contimmm theory of defect, or the field theory of defect, is an important branch in modern solid mechanics and aims at building a bridge between macroscopic and microscopic researches of the elastic and inelastic behavior of materials.

The contimmm theory of defect, or the field theory of defect, is an important branch in modern solid mechanics and aims at building a bridge between macroscopic and microscopic researches of the elastic and inelastic behavior of materials. It is also considered a combined science developed from the interactions between solid mechanics,modern physics and modern mathematics. The present paper systematically introduces the main developments and up-to-date results in this field. It is divided into three parts. In the first part, the kinematics and geometric theories of deformation of a continuum with dislocations and disclinations are discussed including both earlier results by Nye, Kondo, Bilby and Kroner, etc. and our recent works on the derivation of nonlinear kinematic field equations in terms of Cartan eqnations of structure on 4-dimensional material manifold. In the second part, the gauge field theory of defect continuum is reviewed in detail stressing on the development of dynamic equations for the continuum. The third part of the paper is devoted to the application of the continuum theory of defect to the construction of constitutive equations of elasto-plastic materials.
