The modern high-speed printing press has a higher requirement on mechanic properties and axial bounce.
In order to avoid interfering and guarantee the metering equipment complete and does not affect press' normal running, it’s necessary to select the non-contact type measurement mode.
As it is affected by the vibration of the sheet feed cylinder and the gear and so on, the value of the cylinder’s axial bounce of the first set is big.
Fig.5 The curve about the value of the transfer cylinder’s axial bounce change with the speed Conclusions 1) The value of the press cylinder’s axial bounce can be measured precisely for the dynamic states by the laser Doppler non-contact type vibration meter. 2) Cylinder's fit-up gap is the main factor that affects the value of the cylinder’s axial bounce.

Main pollutants Asphalt was widely used in waterproof, paints, plastics and rubber, hence, the amount of asphalt was increased, moreover, the aggregates and equipment in thermal and mixing processing would increase smoke emissions, while in the course of use, the components of asphalt will be leached out to a certain extent due to external factors such as acid rain, ground de-icing salt and oil [4].
Nonpoint source air pollution affects air quality from sources such as smokestacks or car tailpipes.
Experts have pointed out the inevitable contact with water between water and asphalt could be beneficial to asphalt leaching, thereby, affect water quality.
According to one of two studies conducted by the Blue Ridge Environmental Defense League, property value for residential homes near asphalt plants have reported losses of up to 56 percent.
Environmental performance and mechanical analysis of concrete containing recycled asphalt pavement (RAP) and waste precast concrete as aggregate.

For the purification of wastewater and harmful impurities, mechanical, chemical, physicochemical and biochemical methods are used.
In turn, slurry storage facilities occupy significant areas and adversely affect the atmosphere and the lithosphere.
Also, dry separation is the least energy-intensive, since it is based on the natural property of the magnetic attraction of iron ores [5-7].
The recovering capacity of the fluidized bed separator of the dry separation depends on the characteristics of the magnetic system, the physico-mechanical properties of the particles of the separated mixture, and also the geometric parameters of the operating zone.
To study the dependence of the total extraction factor of magnetic particles on the thickness of the initial layer of the separated mixture, we set d = 29.8 μm, αi = 15 deg, vk = 0.02 mps in formula (2).

(3) Analyses of the codes mentioned above reveal two main aspects of factors affecting flexural stiffness, which have also been concluded by previous test results, i.e. exterior load factor, Mcr /Mk, where Mcr and Mk represent cracking moment and service moment, respectively, and inner factors including initial elastic flexural stiffness, B0, and longitudinal reinforcement content, ρ.
Unlike them, the suggested formula here is easier to use for its simpler unified form and clearer concepts reflecting main factors' influence on flexural stiffness.

We report on the die bonding processes and how the surface roughness and metallization schemes affect the processes of die bonding in 4H-SiC device fabrication using a soldering test and die shear test (DST) with differently prepared 4H-SiC samples.
Introduction Silicon carbide (SiC) is a promising material for device operation at high power, high temperature, and high frequency because it has prominent properties, such as high-breakdown electrical field, wide-energy bandgap, and high electron saturation drift velocity.
Conclusion We investigated the die bonding processes regarding how the surface roughness and metallization schemes affect the process of die bonding in SiC device fabrication with differently prepared 4H SiC samples.
Our results indicated that the surface roughness is also one of the most important factors to improve the die attaching to electroplated Cu plates for final packaging the devices.
In addition, in order to apply SiC devices for high temperature environments, further research such as reliable thermal-mechanical modeling, mechanics of material behaviors at elevated temperature (up to 600 �), and new classes of composite materials offering thermal conductivity up to 2400 W/cm 2 could be required.

The Symposium was devoted to all aspects of high-temperature degradation of materials resulting from the main actions of hightemperature, chemical, and mechanical environments.
These were equally divided among the effects of mechanical constraints on oxidation, thermal cycling effects (especially stress measurement), and erosion behavior.
[n reviewing opinions among the participants of the technical content of the Symposium, there was some sentiment expressed that there were fewer sessions than at previous Symposia that featured intense examination of the mechanistic aspects of a given topic, such as occurred with, for instance, the factors affecting scale spallation in Syn1posium IV, and more papers that presented results that lacked significant mechanistic explanation.

To improve the performance and widen the practical application field, the mechanical properties of 3003 Al alloy have been widely studied in past decades [4-7].
Dynamic recrystallization (DRX) plays an important role in reducing the flow stress and the grain size as well as a powerful tool for controlling mechanical properties during 3003 Al foil is produced through hot rolling [8-11].
The aim of this investigation is to obtain 3003 Al alloy with different metallurgical quality by different melt-treatment methods, discuss the relationship between metallurgical quality and hot deformation activation energy (Q), and establish the mathematical model of DRX critical strain and the Zener-Hollomon parameter, which is beneficial to predict and achieve the desirable mechanical properties of the final product. 2.
Dislocation moving and acting reciprocally are essential for plastic deformation, which is remarkably affected by metallurgy defects of 3003 Al alloy.
It is the main factors that oxidation inclusion (Al3O2) in the 3003 Al alloy to block deformation.

Combined numerical simulation and microstructure characterization for prediction of physical properties in extruded aluminum alloys W.
This phenomenon is present in many structural aluminum alloys extrudates and its presence should be eliminated or at least significantly reduced because of the mechanical properties and aesthetic points of view.
Both mechanical properties and surface quality of an extrudate can be affected by PCG formation.
In general, the PCG structure can be controlled by several factors: monitoring the exit temperature and extrusion speed, increasing or decreasing recrystallization inhibiting elements, and maximizing the extrusion ratio to obtain a critical strain.[11] Previous investigations have attempted to understand and predict PCG formation.[12-18] Many times, PCG formation is attributed to the strain gradient inherent in the extrusion process.

The analysis of the literary source and the practice of metalworking indicate that composites, due to their fragility, are practically unknown when cutting the combined surfaces with impact, although their potentialities, due to their unique physical and mechanical characteristics and cutting properties, could be used [6-12].
Comparison of physical and mechanical characteristics of composites.
Dynamic and vibrational loads affect the condition of the treated surface.
The cycloidal shape of the profile helps to reduce the force of friction of the chips on the front surface, which ensures the preservation of the tool material for a long period of time under the rational conditions of cutting-in of the cutting element into the workpiece, since friction is one of the important factors affecting the cutting forces, the temperature of the tool contact surfaces and the state of the part surface layer.
Osadchii, Improving performance of cBN cutting tools by increasing their damping properties.

However, there are few reports on the explosion damage properties of a concrete gravity dam that experiences a strong underwater shock wave.
Because the strength is may be more important to affect the damage of the model dam.
But the damage process is affected by many complex factors; thus, it is difficult to clearly judge whether the damage pattern of the model is similar to the prototype, and this issue may continue to present problems.
However, using the hammer impact test, we can compare the properties of various protective measures to determine appropriate protective measures.
