Materials, used to produce testing specimens of reinforced concrete, are sand coming from natural river, Taishan C32.5 cement, tap water, AR fiberglass and 20# steel fiber (which diameter is 0.9 mm).
Mixed materials are filled into specialized mould, which size is 50×100 mm and will then be shaken and pounded.
To most architectural materials, smaller Poisson ratio and higher residual strength are also hopeful.

At present, Fractal theory has been widely used to study the common irregularities in nature, such as metallic materials and geomaterials [4].
The cost of resin in SiO2/UPR granular composites accounted for more than half in raw materials.
This study shows that the fractal dimension plays a role of linking the microstructure and the macroscopic properties of the granular composite materials.
The fractal dimension can be used in granular composite materials design, evaluation and prediction.

Then central parameterization account oxygen concentration, the mass of the bed material, the mass of residual carbon, and total energy in each section.
The output variables of the model are oxygen concentration, the mass of the bed material, the mass of residual carbon, and the temperature in each section.
Besides increasing the oxygen content of primary wind will decrease excess air coefficient, decrease primary air flow, thus produce a significant impact on fluidization, and thereby affect the stability of the materials of the furnace.
Main nomenclature Oxygen concentration / (mol·m-3) The mass of bed material / (kg) The mass of residual carbon / (kg) Bed temperature / (K) Greek symbols Coal combustion efficiency Subscripts 1.

Having stability and biocompatibility, and taking into account all the coating and surface activation
methods, titanium is one of the most attractive implant material [3,4], but building a nano-tube
structure could lead either to an improvement of a quite large range of properties as changing of
hydrophilic - hydrophobic balance, increasing biocompatibility, changing nano-porosity, stability,
etc.

However, faced with practical problems, such as irregular geometric plane, complex and diverse boundaries and constraints, material nonlinearity, contact problem ,resolution analysis methods the backdrop of a complex geometric plane irregular, boundary and constraint conditions is complicated, materials, such as nonlinear contact problem classical analytic analysis method can do about it.
In recent years, as the wide application of composite foundation technique in the foundation treatment ,separate analysis method can comprehensively reflect mutual coupling between piles and soil about composite foundation, interaction between foundation and fundamental, the nonlinear characteristics of the materials.
DP model is applied to soil, and linear elastic model is applied to the remaining material.
