In filled composites, three types of influence of interfacial interactions on properties are determined: surface, bulk and diffusion [6].
In this case, the main factors of this influence are the total number of surface-active centers and their acid-base ratio, which characterizes the overall acidic, alkaline or neutral nature of the filler surface.
Calculations showed a significant influence of the energy properties of fillers on the FSE of epoxy composites ED-20+DETA+filler.
Therefore, the value of γds can be a reflection of some properties of polymer composites.

The precision of finishing temperature effects not only directly the setting of draught pressure, shape of strip, load distribution and the strip thickness precision at finishing rolling exit but also structure properties of hot rolling and products[1-4].
The structure and precision of the setting model are important for finishing temperature control. 1 Finishing Temperature Control and the Facilities Water cooling is a economic method for steel TMCP, steel finishing temperature control and coiling temperature control are important to product mechanical properties[�,1�] as shown in Fig. 1.
� Fig.2 Layout of facilities of finishing temperature control 2 Speed Setup of Finishing Rolling The running velocity of strip in finishing mill is the main factor, which affects the heat transfer in the inter-stands, as well as affects the micro-tracing precision of the strip sample at the inter-stands.
The inter-stands distance is fixed, the strip has the new thickness and the length after each stand, as so on, these factors make the inter-stands micro-tracing difficult.

Compared with conventional liquid die casting process, rheo-diecasting process had unique advantages in reducing the internal defects and improving mechanical properties of castings.
During the filling process, there were two factors which affected the filling behavior of the fluid together with each other.
This reflects not only the pseudoplastic behavior of fluids under high shear rate, but also the Newtonian behavior under low shear rate, which is more in line with the rheological properties of semi-solid alloy slurry.
Meanwhile, the small solidification shrinkage in rheo-diecasting also helps to reduce or eliminate the defects of the casting shrinkage loose, and thus has unique advantages to improve mechanical properties of castings due to reduction of internal defects.

Therefore, dynamic magnification factors should be multiplied to consider the effect of the high mode.
Put every equivalent damping ratio of each mode into the formula, and horizontal maximum affecting coefficient can be figured out.
Preliminary judgments of the number of adding storeys Number of adding storeys is influenced by many factors: needs, planning requirements, the carrying capacity of the original structure (vertical bearing capacity, horizontal bearing capacity), the total cost of investment (adding & reinforcement), time limit for a project etc.

In many kinds of characteristics of microspheres, the important factors which influence microspheres various kinds of application are the size, dispersion, morphology and surface properties of microspheres [2].
Into a four-neck round-bottom flask (250ml) equipped with mechanical stirrer, condenser, and thermometer.
The thermal properties were analyzed by differential scanning calorimeter (DSC, NETZSCH 204) with nitrogen atmosphere, and the heating rate is 5˚C/min.
However, the factors that affect the particle size distributions are very complicated.
The polarity of dispersion medium is one of the most important parameters that affect the size and size distribution.

However, a mechanical layer removal will affect the local residual stress distribution.
Finally, it must be mentioned that the actual residual stress distribution in thermally sprayed coatings has been recognized as one of the important key factors for fatigue and failure behavior of the layered component [10].

The rock abrasiveness is one of the fundamental parameters of the rock’s mechanical and physical properties, so the investigation on rock abrasiveness can guide the appropriate selection of the bit, the improvement of rock-breaking efficiency, the prolongation of the working time, the reduction of the cost and the improvement of the rock-breaking tools design[1].
Combined with technical parameters, collected through debugging the device, the orthogonal experimental method with three factors and four levels is used to determine the drilling parameters of rock abrasive experiment.
(4)The suggestion is to research the relationship between rock abrasiveness and physical mechanics property in the direction of rock mineral component and cement property to deduce the corresponding relation.

The Compilation of Nonlinear Analysis Program for Externally Prestressed Concrete Beams Huiju Cai1, a, Jianmin Zhou1,b and Ying Gao1,c 1 Department of Civil Engineering, Tongji University, Shanghai, China, 200092 acaihuiju@tongji.edu.cn, b tjzhou2008@163.com, c gascan2002@163.com Keywords: External prestressing; Mechanical behavior; Nonlinear analysis Abstract.
In order to popularize the application of external prestressing technique in green retrofit projects, it is necessary to have a depth exploration on the mechanical behavior of externally prestressed concrete beams by numerical simulation method.
Numerical simulation analysis method enables designers to have additional comprehensive understand for the mechanical characteristics of either structure or component, and therefore both designing and constructing measures would be close to the reality with good performance.
Verification Program In order to popularize the external prestressing technique’s applications in green retrofit of existing structures, and further understand the externally prestressed concrete beam bending property, especially in low-strength concrete beams, Tongji University conducted the experimental research with 12 simply concrete beams strengthened with external prestressing[1].
(a) beam L1-1 (b) beam L1-2 Fig.5 Load-deflection relatives from numerical simulation and test Conclusions 1) Based on the analysis methods of both geometric nonlinear and material nonlinear, the nonlinear analysis program for externally prestressed beams has been compiled. 2) Compared with the experimental results from 12 concrete beams, the verification results indicated that the nonlinear analysis procedure could clearly simulate the mechanical performance of externally prestressed concrete beams. 3) The external prestressing technique is a very important technical measure in the green transformation of existing buildings, through this program it was able to make reconstruction projects more reasonable and economic with advanced analyses in possible affecting factors in structures during reconstruction processes, together with the changing rules of bearing capacity, stress increments and deflection.

The basic property of this grating is that it becomes a narrow band optics filter with the centre of resonance wavelength.
Fig.1 FBG sensing principle Within all of external factors which cause FBG wavelength drift, the most direct is deformation, because whatever stretching or compressing to grating will be bound to cause grating period to change.
It provides the most basic physical property to make optical deformation sensor with optical FBG.
When leakage happens, the optical fiber nearby is affected by the leaked high pressure gas, which causes the fiber to bend and tremble.
