However, it is in combination with binders that they realize their unique properties, giving solutions fundamentally new and important properties.
The setting time of gypsum depends on many technological factors.
From the above data, it can be seen that the addition of B practically does not affect the water-gypsum ratio.
Effect of chemical modifying additives on the setting rate and other properties of the gypsum composition Experience No.
The softening factor is 0.70, which indicates its high water resistance.

Problem Formulation The main concern about scratches in metallic components in aerospace industry is their effect on mechanical properties.
In the first case, it is not expected to have a significant influence on the mechanical properties of the part.
The clad layer has different mechanical properties and different corrosion resistance, so the behavior of the scratch in the clad layer is expected to be than in the base material (substrate).
The path radius and the relative depth are added to the clad layer (if any) because it is expected to also influence the mechanical properties.
Scratches with a small path radius can act as a stress concentrator, so they are expected to have a negative effect on the mechanical properties of parts.

Introduction Grain size can be regarded as a key microstructural factor affecting nearly all aspects of the physical and mechanical behavior of polycrystalline metals [1].
The hot pressing and sintering processes always be associated with grain coarsening, which leads to deterioration of the mechanical properties of the component [4].
This indicates a significant degree of inhomogeneity in the distribution of mechanical properties across the disc cross section.

Judges classified strawberry properties on a scale of 0~10.
Due to this gas flow was controlled by suitable barrier properties of packaging material, equilibrium was achieved.
Fruit firmness was one of the important factors which can decide strawberry quality and its post-harvest physiology.
So the rot grade was a main factor limiting strawberry shelf life.
The appearance, smell, and color of the fruit were important factors that customers considered when purchased strawberry.

The rigidity failure rotational speed is higher the strength failure rotational speed, the connection strength between cutter body and screw bolt affects directly the safety of cutter.
The periodic change in cutting force affects directly machining quality, machining efficiency, and the reliability of high speed end mills [3, 4].
According to the property of the Dirac Function, Fx(t) and Fy(t) are transformed by Fourier Transform [10], we can construct the frequency spectrum functions of dynamic cutting forces dte(t)F(f)P ft2j x ox π− +∞ ∞−∫ ⋅= , dte(t)F(f)P ftj2 y oy π− +∞ ∞−∫ ⋅=
The number of teeth participating in cutting, the rake of cutter, and cutting parameters are important factors affecting the safety and high speed milling performance.

Consider the influence of multi-factor to the transmission inaccuracy of the output.
In Adams, Define the material properties of each unit.
The inaccuracy of manufacturing and assemble was affected by many factors and has complex combination which should conduct analyze separately.
Paper only considers the key factors which have influence of transmit error in the second level of RV reducer: (1) Deformation in the transmission parts (2) Backlash between crank shaft and bearing (3) Backlash between cycloid gear and pin gears Deformation in the transmission parts.
But the backlash was influenced by gap, deformation and many other factors.

Xue Liping et al [3] analyzed the closure of roll pass in Accu-Roll mills, and pointed out that it is affected by the guide disc location.
Description of the model The size of pierced shell is 155×9 mm, and the material of pierced shell is C22, which is read from MSC.Superform database including the mechanical and thermal property of the material.
The frictional factor at the interface between the piercing roll and workpiece is given as m1 =0.7; at the interface between the guide disc and workpiece the frictional factor m2 =0.5; and that at the interface between the plug and workpiece is given as m3 =0.2.
Considering above factors, the film coefficient to environment takes 0.18 kW/(K × m2), and the contact heat transfer coefficient takes 25 kW/(K × m2) [4].
The force parameters are affected by lots of factors such as steel grade, tube size, temperature and rate of deformation, elongation coefficient, mill setting (tools and the adjusting parameters), etc, and each parameter’s effect is complicated.

Introduction The behavior of grain boundaries with regard to their response to applied forces can be crucial for the mechanical properties of crystalline materials.
As known [1-10], boundary migration caused by an applied mechanical stress can result in a shear strain of the crystal region behind the moving boundary.
(a) Misorientation dependence of measured (points) and calculated (lines) coupling factors for <100> symmetrical tilt grain boundaries and (b) activation enthalpy H of stress induced migration of these boundaries [17].
The obtained coupling factors, however, were found to deviate from the coupling factor calculated according to the tangent rule (Fig. 3).
An increase of the migration activation energy with rising impurity concentration suggests that the migration mechanism is substantially affected by the solute segregation.

And the flow-induced stress causes to anisotropy and optical property, affecting surface molding state of part [3].
The conventional studies on residual stresses are limited to the thermal stress, a dominant factor of residual stress, and deformation of part.
Governing Equations and Material Properties Polymeric flow in the filling phase can be approximated to a flow between two plates separated by a small gap as shown in Fig. 1.
Materials for the thin wall applications requires good flow properties.
So, the residual stress affects the part surface quality seriously.

From this study, it is noted that as the frictional factor, the angular velocity, the aspect ratio increase, the relative compression force decreases.
