Experimental material selection and experiment scheme In order to test the filling material that mainly composed of loess and the fly ash in the physical and mechanical properties, research the feasibility of loess and of fly ash as filling material and gain the new kind of filling material and it's mixture proportion, the experiment was carried out as follows: The major indexes of backfilling materials the requirements of raw materials.
Influence factors and levels are designed is shown in Table 1.
Various factors influence on the uniaxial compressive strength of specimen The processing of experimental data.
Each of the different indicators of filling slurry such as setting time, hardening rate and the strength etc, the strength of specimen is one of the most important indicator, so uniaxial compressive strength is the most valuable result for this experiment, by using experiment results analysis method of the orthogonal for judging the each factors and levels that affect on the results.
In order to further understand the influence of various factors on the experimental results, get the optimal material ratio .

In this paper, air bending is simulated using finite element method, but simulation parameters directly affected prediction precision.
But, air bending is influenced by a combination of various process parameters, such as the tool shape and dimension, the temperature change and frictional contact condition, the material properties, and so on.
In analysis process of forming, one of the most important factors is the calculation of springback.

The biodegradation process of bioplastics is influenced by several factors such as pH, water content, temperature, nutrient availability, and temperature.
To improve the physical properties of this bioplastic, glycerol is added as a plasticizer and chitosan as a reinforcement [5].
The addition is done so that the plastic film has mechanical and physical properties that can be improved and so that it can be protected from microorganisms that can damage the plastic film.
The tensile value for moderate properties (Bioplastic Standard) is 1-10 Mpa.
In making this plastic sample, optical microscope testing was carried out to see the surface physical properties of a bioplastic sample and tensile testing to determine the mechanical properties of a bioplastic sample.

Apart from the exposure and their frequency, there are other factors that influence the occurrence of these disorders, such as: the environment, the health status, stature, weight and sex [1-5].

Ensembles 2, 3, and 4, and subsequently for the vibration attenuator device ensemble 5 (Fig. 4a and Fig. 5a), comply with the same anthropometric properties from table 3, as in the mechanical model proposed by figure 3, respectively the Body Blocks with the masses m1, m2, m3 and subsequently m4 for the vibration attenuator device.
In time, all these symptoms can degenerate in occupational disorders, such as VWF and other professional illnesses (affecting the nervous and circulatory systems, spine, hearing and sight, etc.).

So, what were the key factors that the landslide occurred?
However, the landslide incident, as well as the Vajont reservoir rock landslide, showed that can't use pure rock and soil mechanics point of view to treat with bank slope stability problems, which has complex evolution history and environmental conditions, especially not analyze pregnant and sliding mechanism of the landslides just from the mechanical properties of rocks or sliding surfaces.
Now pregnant and sliding mechanism of the Qianjiangping landslide was revealed by analyzed the corresponding relationship of the slope structure, dynamic change of the landslide main inducing factors and each part deformation and failure of the slope on the sliding threshold.
At the moment, the mechanical properties of latent sliding surface itself of the Qianjiangping landslide is unlikely to have a big change.
That was, after hydrogeological structure of the slope changed, inducing factors dynamically had only the possibility of starting the landslides, groundwater ​​pressure would become main mechanical mark which caused the rock landslides.

The microstructure, morphology and corrosion properties of the melting layer were analyzed by optical microscopy (OP), scanning electron microscopy (SEM), simulated corrosion test, respectively.
However, poor corrosion resistance and inferior wear properties have hindered its wide applications.
The properties of the plasma melted layer are affected by current, voltage, compressing rate of plasma beam, gas flow process parameters [17].
The properties of plasma melted layer are affected by current, voltage, compressing rate of plasma beam, gas flow process parameters [17].
Current value is main factor to determine the power density and the melt depth.

Luminescence properties of Tm3+ /Dy3+ co-doped zinc-aluminum phosphate glasses for white LED C.
The luminescence properties were investigated by excitation and emission spectra.
Many factors would affect the Eu3+ → Eu2+ process in glass materials prepared in air, such as glass optical basicity, rigidity of glass network, valence of glass network modifier oxides, etc..

Applications of specific properties of various titanium alloys applied in modern technology processes were discussed.
These alloys defined in Japan as Super-TIX-series have special properties, while all the factors, which may cause corrosion cracks, high-temperature corrosion in salts, hydrogen embrittlement, that is all of damages, which titanium alloys with addition of oxygen, nitrogen and iron are exposed to, were eliminated.
Titanium-zinc plates have besides wonderful optical and technical advantages, also the properties of inflammable material that protects against lightning strikes and against electro-smog.
Possibility for using original color and surface protection against getting dirty, starting from factors related to its exploitation show that titanium is an extremely durable material, the surface of which will look the same not only years, but after decades.

Make full use of the absorption function, ion exchange, and other special properties which zeolite powder has.
However, there is no single way for the comprehensive evaluation of these three properties of self-compacting concrete.
Effect of sand ratio, binder material quantity and components of mix material together on the concrete flow and filling properties was studied.

Most PM components are exposed to cyclic loading over long periods of time, and the endurable stress amplitude is an important factor considered in many applications.
Introduction Often the fatigue performance of a material is only characterized by a fully reversed bending strength amplitude for comparison purposes, neglecting a multitude of independent variables that may affect the endurance limit.
Thus, in many cases, the effect of some of these variables must be guessed, which requires higher safety factors in calculations.
Effect of Density on Fully Reversed Endurance Limits In general, a parabolic dependence of a mechanical property P on density ρ is observed [1, 2] m 00 )/(PP ρρ=
Case hardened materials have been excluded here, because in materials with property gradients the ratio is very size dependent.
