Microstructure is considered to be one of the most important factors determining the properties of a hardened cement system.
Speaking of all those factors that adversely affect the binder hydration, it is essential to mention a separate impact on the system of low and negative temperatures [1, 2, 5].
Efficiency of using this method is determined by the following factors:  · Octane is absolutely inert to the products of hydration of the binder
In practical terms, this can lead to significant reduction of strength and performance properties of the material. 
Structural and wetting properties of fuel cell components.

Introduction Excellent mechanical properties in combination with low density are the key features for lightweight structures in automotive and aerospace applications.
But due to the low processing temperatures and short cycle times the amount is nearly negligible and should not affected the mechanical properties significantly.
So the modulus could be increased by the factor 6 and the maximum bending strength by the factor 1, 6.
The components show advanced mechanical properties even if they are reinforced with common carbon fibers only.
The mechanical properties have to be fitted to possible applications by arrangement of fiber volume fraction and architecture and in addition by tailor-made fiber matrix interfaces.

Non-stability factors affect stability of radial ring rolling process, and lead to fluctuating of ring position.
It can be as an important index used to measure the property of the rolling process.

Analysis of Existing Concrete Bridges Material properties.
Material properties are important input data to the load-carrying capacity determination.
In the case of concrete bridges, it is needed to specify material properties of concrete, reinforcement and prestressing steel.
In cases, where the consequential distribution of internal forces and stresses in the existing concrete is affected by the inhomogeneity, respectively time factor is affecting properties of concrete, it is necessary to take into account the impact of the construction process and load history to determine the actual response of the structure.
To determine deformations, the mean values of material properties are considered and the effects of shrinkage and creep and the impact of cracks should be taken into account.

Finite element analysis of wind turbine lifting platform bridge structure Yu Tang a, Yuhou Wu, Ke Zhang, Jia Sun, Enwei Song School of Shenyang Jianzhu University,Institute of mechanical engineering, Shenyang ,110168; a2233870124@qq.com Keywords: Wind turbine; Bridge structure; ANSYS Workbench.
Compared with the standard, it shows that this structure satisfies the strength and stiffness requirement and will generate frequency affecting human body higher than the nature frequency.
So, the two main beams’ stress are different.Considering the heavy lifting caused by sudden dynamic loads and wind loads, select the dynamic load factor as Φ=1.2 , the role of the force in the main bridge as shown in Table 2[3].
We can placing reinforcement or change of thickness to improve its mechanical properties for designed. 3.
Got the platform’s natural frequency and predict the dynamic vibration mode; Avoided the frequency which affect to human’s body.

Significant microstructural changes in the stir and thermo mechanically affected zones (TMAZ) have been observed previously [5].
Base material properties obtained, at room temperature, via uniaxial tensile and hardness tests are shown in Table 2.

At elevated temperatures, additional thermally activated and time-dependent factors are acting in combination with mechanical fatigue.
The elevated temperature tensile properties of AA5083H111 also indicate a marked decrease in strength at 200ºC as shown in Fig. 7.

One fiber stain measure and control system has been designed to meet the problem that the magnitude and uniformity of the fiber strain directly determine the properties and longevity of the carbon fiber continuous sucker rod during the pultrusion process.
Among these parameters, the homogeneity of fiber strain will directly affect the distribution uniformity of fiber in CFR rod body's cross section and determine CFR rod body's tensile strength and longevity, so it has to be controlled and adjusted accurately.
Not only because of the traction force of pulling and extruding the CFR is very strong, but also requires the strain measure and control system couldn't generate oversized additive load, further more, the traction force has high-frequency time variation owing to affected by various factors during the producing process, the sensor, that used to measure the fiber strain and designed base on fiber micro-bend principle, must be extra small, very good in frequency response characteristics and sensitivity.
The fiber strain sensor have been developed is one micro silicon pressure sensor[12] which using Silicon film as sensitive element which with good mechanical property and fabricated with Silicon integrated circuit technology and three dimensional processes.
Moreover, it has merits of quick response, small fluctuation of torque and rotational speed, high position accuracy, good mechanical characteristics and good lineation of regulative property etc.

The calculation procedures of the derived theoretical model are compiled by applying the Matlab software, and are employed to analyze the affecting elements of diffusion.
Fracture width is the primary factor considered in low water-cement ration.
（4）The fracture network is very complicated, and the effective factors influencing diffusion are much more; the single fracture model is the basis of building the diffusion model of fracture network, which is the will be the next step of work in the future.
