Residual stress is an important factor in quality of the welding joints[1].
Residual stresses do not only affect the corrosion, cracking and fatigue strength in the mechanical properties of the welding joint, but also greatly affect physical mechanical characteristics of the material, so the measurement and calculation to the residual stresses are always important details to be studied in high-speed train welding field.
Though laboratory test has reality, the results in the same model measured in different times can have great diversities, the results cannot avoid the influences caused by personal and environmental factors.
According to the mathematical model above,when using Sysweld to simulate welding thermal elastic-plastic finite element, we needed to take the materials’ nonlinearity into account, that means the correlation between the material properties and the temperature should be considered.
Fig. 8 shows that lateral residual stress has no obvious distribution rule, this is mainly because the factors infulencing the transverse residual stress are more, all the factors including the heterogeneity of materials, the irrationality of the component design brought by designing, the welding sequence and direction will affect the value and distribution of the lateral residual stress.

As a result of the experimental data processing, the equations reflecting the influence of the varied factors on the studied indicators of the low-clinked binder properties have been obtained.
Taking into account the importance of the regression coefficients it is possible to draw a conclusion that, first of all mutual influence of factors x1 and x2 has affected the size R28.
As the overdose of superplasticizer C-3 or the increasing of the water-binder first of all affects the durability of solutions and concrete, as the mutual influence of the specified factors on the 28th day has decreased considerably.

The influence of designing factors on product will be restrained in an allowable range by adjusting the design variant and its tolerance properly.
In terms of detailed design information of evaluating objects and confirmed evaluating targets, taking into consideration of uncertainties on evaluation information, the fluctuation of mass properties membership degree is used to indicate the fluctuation of design proposal, and thus may get a design proposal with better robustness.
The process of tolerance design is to choose the most suitable tolerance for each parameter, i.e. considering the influence of parameter fluctuation on the mass properties, discussing whether to adjust the tolerance of some parameters or not from the economic point of view.

Effect of Samarium Oxide on Structural and Optical Properties of Zinc Silicate Glass Ceramics from Waste Material I.A.
Given these factors, many scientists focused their interest on trivalent samarium ions as a luminescence centers in deep red emission arising from conduction band 4G5/2 → 6H9/6 transition [2].
The samples Morphological structure and optical properties of pure and doped zinc silicate were detected.

In present article, factors restricting the development of membrane distillation-crystallization such as the performance of membrane material and the mass transfer/transfer efficiency were introduced, the process enhancement and sediment control measures of crystallization were reviewed.
In the present article, restraining factors of the development of MDC lie not only in the performance of membrane material needed further improvement but in the mass transfer/transfer efficiency and sediment control measures of effective composition of crystallization needed more enhancement.
Compared with traditional separation process, MDC has these advantages: (1) MD operated under normal pressure has lower requirement of equipment and mechanical property of membrane. (2) Energy consumption is considerably reduced for lower operated temperature than normal boiling point of solution. (3) Hydrophobic microporous membrane preventing pollution from hydrophilic materials well is easier to clean. (4) Nonvolatile matter in the solution can be completely resisted and so forth.
Many cleaning methods can be used for membrane fouling, for instance, liquid recoil, gas recoil, chemical cleaning, mechanical vibrations, low frequency ultrasound etc [9].
In the heat/mass transfer process of MD, temperature polarization directly affects drive stress, while concentration polarization affects the efficiency of MD when feed concentration is closely saturated [19].

Vibration affecting the passenger’s body leads to irritability, headaches, impaired attention, an increase in the likelihood of neurosis diseases, etc [8].
Therefore, promising direction is the development of difficult combustible epoxyurethane mastic with increased vibration-damping properties and the necessary physical and mechanical properties for cladding the internal metal surfaces of railway rolling stock bodies.
The aim of this work is the development and evaluation of the possibility of using difficult combustible epoxyurethane mastic with increased vibration-damping properties and the necessary physical and mechanical properties for cladding the internal metal surfaces of railway rolling stock bodies.
As the main method for studying viscoelastic properties, we chose the method of dynamic mechanical spectroscopy, which was implemented on a torsion pendulum-dynamic relaxometer [22].
Therefore, it was of interest to study the effect of dispersed mineral fillers (APh and AM-1-300) on the dynamic mechanical properties of epoxyurethane compositions.

Analyses of microstructure and testes of mechanical properties for cements from the two different mud showed that the cements composed of 25 % of different mud respectively can reach the national standard of 42.5 grade cements.
Because of different disposal processes, the properties of residual slag mud are different from dry disposed steel slag.

Introduction Currently High P-T(High Pressure and Temperature) rheometer is widely used in the Earth's interior material rheological properties and dynamics research [1].
The curve d shows that the different contact types on the two end surfaces of core mainly affect the axial stress nearby.
The bevel of pusher and pedestal is a key factor to affect the axial stress, by which the axial preload can be enhanced at the inner surface of core.
The end pressure and the angle of bevels are the two key factors affecting the axial stress of core and the two reasons leading to the yield of pusher and pedestal.

The effects of workpiece geometry, cutting mechanics, process factors, and the material factors on surface roughness have been overlooked in most studies of surface generation in the FTS machining of optical microstructures.
There is a need to develop deterministic models that take into account both the process and material factors in the generation of the surface.
Factors Affecting Surface Generation.
As shown in Figure 3, it is also interesting to note that the properties of materials, tool wear, band width and stroke of the FTS, and the relative vibration between the cutting tool and the rotational spindle also play important roles in material removal process.
It is found that only depth of cut contributes little effect to the surface quality, while feed rate and spindle speed play the critical roles in affecting the form accuracy of the profiles of the microstructures.

The knowledge about physical and mechanical properties of the bricks is quite incomplete, especially the earthquake resistant behavior, which limit their more widespread application [3-5].A four storey masonry building model with 1:3 scales is built.
Compared with the conventional recycled concrete brick, the composition of the construction waste recycled bricks is more complex, so its’ mechanical properties under load will change greatly.
