There are some various advantages of activated carbon, such as excellent adsorption ability, good catalytic properties, fine chemical stability, high mechanical strength, heat-resistant, so it is widely used in the fields of food processing, chemical, medicine, military and so on.
Single factor experiments and orthogonal test are adopted to study the impact of activation parameters on the activation effect.
Single factor experiment results Impact of activation temperature on the iodine value.
Results of orthogonal experiment According to the single-factor experiment results, the activation temperature, impregnation ratio and activator concentration were selected as the three main factors affecting activation effect, and three levels of orthogonal experiment to determine the cross influence of various factors on the activation effect.

Factors, such as temperature, pressure and the degree of crystallinity on the product qualities are analyzed.
Besides, crystallization is a common phenomenon of polymers, which may affect the molding ability of polymers.
This phenomenon can be explained by mechanical theory of small deformation.
The mainly influence factors on the micromolding is temperature and time.
Here, we will study on another potential influence factor: crystallinity, which has great influence on the mechanical and electrical properties of polymers.

The appearance, physical properties and dimensional accuracy of plastic production largely depend on the control of mold temperature.
We can reduce products deformation, enhance mechanical properties, improve visual quality and dimensional accuracy by adjusting and maintaining appropriate mold temperature; at the same time we can shorten the injection molding cycle to improve the forming productivity.
Therefore, an appropriate choice of the parameters of the mold cooling system will help to lower production costs and improve the quality of plastic parts.[1] Mechanical optimization design is a modern design method that is based on the theory of mathematical programming and takes computer as a tool to find the best mechanical design planning which includes establishing mathematical model, choosing the appropriate optimization procedures and solution by computer.
There exist many factors affecting the effectiveness of the work of plastic mold cooling system and if we take into account the aspects from a given mold material, the cooling medium, the shape of plastic products and process conditions, the design and layout of the cooling pipe diameter is the most important part.

Effect of Different Hole-Making Technology on Fatigue Properties of Directionally Solidified Alloy IC10 Y.
However, the existence of film-cooling hole not only destroys the integrity of the turbine blade structure, but also seriously damages the strength and life of the turbine blade. [4]The irregular shape of film-cooling hole and other factors also seriously affect the surface quality of film holes, which is a thorny problem in the process of hole-making.
Chen [5] studied the effect of the roundness of film-cooling hole on fatigue properties.
Finally, the influence of hole taper on the mechanical properties of components is analyzed by finite element model, and the surface quality of film holes is evaluated to obtain the possible damage to blade structure. 2.
Model and Loading In order to further evaluate the effect of the shape of the real film-cooling hole on the mechanical properties of the component, two finite element models with different tapers of the hole were established for comparative analysis.

In recent years, some scholars begin to combine digital image processing (DIP) technology and geomaterials, with different image information corresponding to different geotechnical materials, to analyze the mechanical properties and monitor deformation of materials[1,2].
Pixel unit is the basic processing objects of the image, with two properties: coordinates and intensity.
Figure 5 shows the total pixel number is 441×599, actual size is 221m×300m, proportional conversion factor R is 0.61475m/pixel, actual area of each pixel is 0.25083 m2.
Compared with conventional modeling, still the following deficiencies exist: (1) Compared with the literature[2-6], although the total number of pixels greatly improved, the establishment of a greater number of pixels or further reduce the size conversion scale factor will greatly affect the Flac3D calculation speed, time-consuming; (2) Although achieving unified operation to the pixels of the same region with the same gray degree to control element size in the horizontal, further exploration of independent subdivision of the grid in the longitudinal direction is expected.

Introduction Aluminium-silicon alloys are known for their excellent combination of properties namely, low density, excellent castability, reasonable strength and stiffness, corrosion resistance and cryogenic properties and good machinability [1].
With an increase of load, more factors act concomitantly resulting in high acceleration of wear rate above the critical load.
The process of removal and regeneration of a tribofilm depends on mainly three factors: load, speed and the sliding distance.

The demand of the economy of the modern car becomes higher and higher, and the lightening design of the vehicle is an important factor in improving the economy.
On the whole frame, we omit each leaf spring lug bracket, the car body bracket and the engine hanging bracket, ignore some small holes in size and having a little influence on the mechanical properties of the frame structure.
The number 3.5 is the dynamic factor for off-road vehicle dynamic strength calculation.
The Measure of the Lightening Design On the premise of not affect the structure and function, reduce the material on the place where the stress is too little.
We can make full use of the mechanical properties of materials to achieve the goal of saving material, reasonable frame structure, and Lightweight frame.

The mechanical properties of the porous scaffolds were determined using a tensile strength instrument (model LRX, Lloyd, Hampshire, UK).
The mechanical properties of the porous chitosan and γ-PGA/chitosan composite scaffolds were also determined using a tensile strength instrument (Table 1).

For that reason, progress in the hydrophilicity and adsorption of attachment factors are both favorable for cell attachment and proliferation.
Mechanical properties of the scaffolds are crucial for their application in tissue engineering [11].

The dynamic methods of the determining of the elastic properties of materials allow to carry out measurements at a small relative deformation (£ 10-6) and have higher the sensitivity and accuracy compared to the static methods [21, 22].
Herewith, the mechanical properties of the material change from elastic to viscoelastic properties.
Secondly, the heating to a temperature close enough to the melting point leads the solid to an extreme (limiting) state, characterized by the instability of the crystal lattice and, therefore, by a special behavior of properties.
The change in the state of a crystal lattice of metal under the influence of the thermal and power factors is determined by its deformation (changing in the interatomic distance) and is uniquely associated with the degree of changing in the young modules.

By adjusting the technical parameters, we can obtain different coatings with the desired properties, such as corrosion resistance, wear resistance and mechanical properties[1].
The organic fibres not only can affect adhesion strength with the nickel coating but also has great influences on the technical conditions of sintering procedures as well as the properties of the hollow nickel fibres.
In this experiment three key factors were considered.
Cheap fibres were considered with the precondition of the above two factors well satisfied.
By comparison the properties of different fibres, we choosed the polyacrylonitrile fibres as the templates of electroless plating.
