Because of their excellent aesthetic properties, ceramics are becoming more common in the use of
dental restorations.
It is known from different studies, that various factors and influences [1-6] affect the construction of the restoration.

Coatings obtained from this electrolyte are characterized by improved physicochemical and mechanical properties [5].
We studied such characteristics of electrolytic deposits as metal current output, the throwing power of trilonate electrolytes and some properties of the obtained coatings from zinc alloys with copper, stibium, cobalt, manganese and lead (Tables 1 and 2).
Where - the primary current distribution depending on the geometric factors of the electrolyzer (in our case ); - the distribution of metal on the cathode in relative units, equal to the ratio of masses of deposits in the near and far cathodes.
The inclusion of non-metallic particles in electroplating causes a number of specific properties of the latter, in particular, high residual resistivity, microhardness, corrosion resistance (Table 2).
Alloying zinc coatings with metals such as manganese, stibium, lead, cobalt, and copper leads to a significant structure refinement, a decrease in porosity and internal stresses, as well as a smoothing of the surface topography of the deposits, which improves their physical and chemical properties.

Since PLA has the similar mechanical properties and processing properties with polystyrene (PS), it becomes the most potential alternative of the conventional cushioning packaging materials [4-5].
In this paper, the form was obtained by hot-press forming and the properties of the material were measured.
Physical and structure properties Expansion ratio was calculated by dividing the increased height of the foams by the height of the mold.
From the experimental results this maybe the significant factors for foam.
However, when pressure increased more than 15MPa, too much pressure affect the growth of the bubble, but this change isn’t as clear as before.

Introduction
Polylactide (PLA) is one of the most promising biodegradable polymers owing to its mechanical property profile, thermoplastic processibility and biological properties, such as biocompatibility and biodegradability.
Different critical properties should be met for various applications.
Enhancement of the cell attachment on the scaffold materials will benefit tissue engineering applications, and thus if independent control of the surface morphology, porosity, mechanical properties and bioactivity of PLA can be achieved, and optimization of PLA material properties for specific applications becomes feasible.
There maybe exist two factors, the viscosity of solutions and the volatility of solvent, accounting for this phenomenon. 1,4-dioxane volatilizes slowly while acetone is highly volatile ,When the 1,4-dioxane content is high, it will reduce the volatility of mixture and volatilize slowly during the spinning process.
The SEM micrographs at different voltages (A) 15 kV, (B) 18 kV, (C) 21 kV, (D) 24 kV 3.4 Effect of collecting distance The structure and morphology of electrospun fibers is easily affected by the capillary-screen distance, which could cause variation of the deposition time, evaporation rate, and electric field intensity.

Its use as pigment in paints [6] is a common practice due to the increase in UV resistance, resistance to corrosion and mechanical property of abrasion of the coatings.
These properties depend on several factors, such as crystallinity, morphology and specific surface area of the material.
ZnO nanostructures have also been used to improve the properties of sensors, solar cells, varistors, among other [6-12].
The powder synthesis route exerts great influence on the properties of the final product.
The drying and heating routes also affect the characteristics of the material.

The high energy generated among the EHP may change the material thermo-physical parameters, affect the overall thermal mechanical properties, cause the material thermal degradation, appear the phenomenon of thermal recession and so on.

We can know that the leakage affect the temperature.
These will affect the calculation results, but some effect temperature high, some lower, so the overall considering that the omitted parts study the effect offset each other.

Ignore the influence of the strength, quality, such factors as the position of the center of mass, inertia and parts appearance.
In order to not affect or make less as far as possible influence to performance, the structure is simplified, the 3D model is established and imported into ADAMS based on Pro/E.

Other properties such as corrosion resistance are being related quantitatively to
microstructure.
Grain boundary properties, such as energy and mobility, can then be associated with the misorientation.
The nodes in the interior of grains are also updated but with numerical factors to ensure that they do not significantly affect the motion of the interfaces.
Current opinion generally holds that both factors are important but that texture is often determined early in the recrystallization process, commonly referred to as oriented nucleation.
In over-simplified terms, mechanical properties are generally well described by average values over a microstructure, whereas the recrystallization process is sensitive to extreme values of distributions of misorientation, orientation gradients, stored energy and other factors.

They have the
property of generating an electric potential in response to an applied mechanical stress and vice
versa.
When left uncompensated, these nonlinearities negatively affect the performance of piezo actuators and thereby limit their application.
Hysteresis modeling and compensation The active suction block's hysteresis output can be influenced by many factors.
The parameters c and k can be estimated using the value of m and the damped natural frequency and the damping factor observed through step or impulse response tests.
