The influence factors of chemical reaction include grinding pressure, velocity, friction coefficient between abrasives and Al2O3 ceramic, and the external temperature [7] as well.
The properties of abrasives and reactants formed between abrasive and workpiece are given in Table 1.
The material removal of Al2O3 ceramic was based on the solid state reaction between abrasive and workpiece, as well as the mechanical action of abrasives, thus the grinding performance of CMG tools were affected by the chemical reaction rate and the nature of chemical reactants.
So the nature of chemical reactants between abrasives and Al2O3 was considered to be main factor of affecting the grinding performance of CMG tools in this paper.
The main factor of affecting the tool grinding performance was the nature of chemical reactants between abrasives and Al2O3.

It is the key point for plastic gear replacing metal gear and own the same properties to improve properties of polymer materials and molding accuracy.
Experimental Procedure Analysis accuracy influence factors of injection molding gear in single cavity by CAE.
Selecting Cool+Flow+Pressure+Warp modular (CFW) analyse the affective factors of the molding accuracy.
Figure 7 is the warp result, which raise from some factors, and the (c) displays the shrinkage of material is the most primary factor.
After molding, some factors, such as ejection, deformation after demolding also need to consider.

The QE22 cast magnesium alloy containing silver, rare earth elements and zirconium is characterized by high mechanical properties and creep resistance of up to 200°C.
Zirconium modifies the size of the grain in the alloy, increasing its mechanical properties in the ambient temperature [1].
An important factor determining the validity of application of welding techniques for repairing or joining the cast magnesium alloys is the structural stability and the stability of the properties of the joint in operating conditions.

Shrinkage and creep of concrete on the mechanical properties of cable-stayed bridge Hengshan Gao 1, a, Tieying Li 2, b 1Architecture and Civil Engineering College, Taiyuan University of Technology,Taiyuan,Shanxi,030024,China 2 Architecture and Civil Engineering College, Taiyuan University of Technology,Taiyuan,Shanxi,030024,China adazhuangzhenbaishi@126.com, blty680412@163.coml Keywords: Cable-stayed bridge.
Mechanical properties.
In addition, the large span cable-stayed bridge is commonly used cantilever cast-in-place construction in phases, the age of concrete of each unit is not the same general, so do their material properties, the role of structure formation and self-respect is by stages.
Fourthly, this analysis does not consider the shrinkage and creep and elastic modulus, the mutual influence of the stress relaxation of cable, the tendon tensioning and prestress loss and other factors.
It recommends that future analysis takes into account of other factors.

Based on the study of unsaturated mechanical experiment, the soil shear strength model formula can be proposed , and the changing rule of unsaturated soil mechanical properties be investigated for the typical levee soil of the Yellow River.
Introduction Affecting by the climate condition in the Yellow River drainage area, the levee soil are in the state of dry for a long time.
Unsaturated soil in the non-flood season appears great strength, less deformation properties.
According to the characteristics and physical and mechanical properties of Yellow River levee soil, the soil specimens are chosen from Shandong Dongping section of Yellow River dike.

The high piezoelectricity and high mechanical quality factor thin films are very important for the fabrications of micro devices.
The Pb(Zrx,Ti1-x)O3(PZT) thin films own high piezoelectricity, however, its mechanical quality factor is small.
The PZT thin films doped with PMnN own high piezoelectricity and high mechanical quality factor, however, the dielectric property is also important parameters for the applications in the micro devices, and so research on the dielectric property of PMnN-PZT thin films is the key point.
The research on dielectric property are also made, and the results show that the doping of PMnN into PZT causes the larger dielectric constants, however, the effects doesn’t affect the combined property of thin films if the doping ratio is smaller 6 mol percent.
In conclusion, the 6% doping ratio is the proper doping ratio, and the PMnN-PZT thin films own proper dielectric constant, besides, the 0.06PMnN-0.94PZT(52/48) films own potentially high mechanical quality factors, and these films are expected to be used in the actual applications such as ferroelectric devices, piezoelectric devices and MEMS.

Mechanical properties of automotive instrument panels with semi-rigid foam Rong Cheng1,a 1.
This article was prepared by one-step car instrument panel with semi-rigid polyurethane foam, through the design of the four factors and three levels orthogonal test program, using Fourier infrared spectroscopy to characterize its structure, measuring its apparent density and hardness properties of transformation, the combination of research influence of the proportion of polyether foam system.
Instrument panel as a large, complex, unique and exquisite cars and interior parts, which combines safety, comfort features, decorative and functional performance in one of these properties directly affect the evaluation of vehicle classes.
In this study, the focus on the water, the ratio of polyether chain extender and the isocyanate index of the overall performance of the polyurethane foam prepared by the influence of that of the four factors affect the semi-rigid polyurethane foam systems.
While each of the three levels of the variable factors.

Effect of Strain Rate on Mechanical Properties of Two-Component Epoxy Adhesive Bond Jan Cidlina1,a, Jozef Žarnovský2,b and Miroslav Müller3,c 1,3Department of Material Science and Manufacturing Technology, Faculty of Engineering, Czech University of Life Sciences Prague, Kamýcká 129, 165 21 Prague – 6, Czech Republic 2Department of Quality and Engineering Technologies, Faculty of Engineering, Slovak University of Agriculture in Nitra, Tr.
One of the affecting factors is strain rate.
The adhesive technology is one of the joining material methods providing possibilities to create the joint with a range of shapes and properties that are not possible to achieve using 'classic' methods [1,2].
An adhesive bond is a complex assembly the creation and following use of which is limited by a number of factors [1,5].
The resulting properties depend on the type of adhesive; nevertheless, better results were shown by adhesives filled with rubber [13].

The structure of alginates played an important role in affecting its properties.
