However, investigations of the boundary properties and accommodation processes in the bulk of the fine-grained material are hindered by the experimental difficulties.
The brittleness of the interface indicates the accumulation of a large number of stable defects such as microcracks on the interfaces after plastic deformation.

Naturally, the number of oxygen vacancies in the perovskite lattice y must decrease depending on the Fe 4+ cations content.
Electron microscopy data confirmed a dense microstructure of the samples prepared, with the average size of isometric grains decreasing from 2-5 µm to 1-2 µm in samples I and from 10-30 µm to 3-5 µm in samples II when x increased from 0 to 0.5, respectively.

Carbonate contains a large number of adsorption cations which have strong hydrophilic, interaction with the colloidal particles soon after contact with water, the formation of colloidal particles and soil particles around a solid combination of the water film, thus reducing particle cohesion, avoiding soil expansion [3, 4].
The maximum particle size should less than 50mm, the gravel is flat and slight grain should less than 20%.

and dolomite rock, with thickness of about 813m; Qingyan group (T2q), gray clay and calcareous clay rock in the upper part, and thin layer of limestone and argillaceous limestone in the lower part, with thickness of 868 to 1117m; Xinyuan group (T2x), clay rock and sandstone interbedded with thin and medium thick layers of limestone and marls, with thickness of 82 to 250m; Yangliujing group (T2y), composition of medium thick layer to massive dolomite, limestone and breccia dolomite, with thickness of 374 to 980m; Longtou group (T2l), medium thick layer to block crystalline limestones, algal limestone and biolistic limestone with a small amount of dolomite, with thickness 1158 to 1254m; Zuganpo group (T2z), made of thin to medium thick layer of limestone and nodular limestone, with thickness of 30 to 143m; Bianyang group (T2b), medium thick to thick layer of sandstone, thin to medium thick layer of siltstone, clay stone and a small amount of limestone composed of rhythmic alternation of grain
Well number was ZF03, with the hole depth of 159.00m.

The relationship between strength and porosity has been investigated by many researchers [8], and a number of models have been proposed to explain the strength-porosity behaviors.
Rice, Relation of tensile strength-porosity effects in ceramics to porosity dependence of Young's modulus and fracture energy, porosity character and grain size, Mater.

Comparison of Influence of Different Greening Structure on Outdoor Temperature in Two Residential Areas The environmental characteristic of the first residential area is as follows: the geographical layout of six-story residential buildings is in rows with south-north orientation; the space between buildings is about 12 meters; the condition of greening structure is good; in the range of 50m*50m, the number of trees is about 40.
The tiny concave and convex of grains on the rough wall surface can guard against glare. 3.

Technology and Experimental Research Plan “Liquid wood” grains can be processed by mold injection, extrusion, calendering, blow molding, deep drawing or pressing into molded parts, half-finished product, sheets, film solder profiles, [2, 4].
After the orthogonality and the number of degrees of freedom conditions have been checked, there were 16 experimental tests to be conducted.

Application of active beds has become possible through the development of powders with the desired properties, particularly suitable composition, grain size, flowability and especially resistance to sintering at high temperatures (temperatures corresponding to thermo-chemical treatment for particular powder).
In this model the number of phases is limited only by computational capabilities and memory capacity of the computer.

A number of standards had been developed for the parameters of recycled aggregate around the world, but these standards are not entirely consistent.
RA’s surface roughness, grain shape, irregular, angular and more attached to the surface more mortar block, which is caused by RA important factor in poor performance.

Quite a certain number of studies investigating the deformation behavior of the Mg-Zn-Zr alloy with low zinc have evolved recently.
This is because that the nucleation and growth of dynamically recrystallized grains are provided higher mobility as the deformation temperature increasing, and decreased the strain rate would also end to the acceleration of activation energy accumulation and dislocation annihilation due to the relatively longer time for the deformation to be completed.
