Constant volume transparent test combustion chambers are extensively used for investigating injection and fuel burning properties of various combustion engines.
The material properties of quartz windows (based on the manufacturer report [5]) are as shown in table 1.
Material properties of fused silica Density 2200 Young’s modulus 72 Poisson’s ratio 0.17 Modulus of rapture (Abraded) 52.4 Thermal conductivity 1.46 Coefficient of thermal expansion 5.4 Specific heat 700 A hex- mapped mesh was used to increase the accuracy of the results.
Results and Discussion Since fused silica has a very low coefficient of thermal conductivity and the period of temperature increase is short, ignition could not extensively affect the quartz windows and it could only increase the temperature of the surface of the windows.

Part of a building substance created out of loam must be blending water which significantly affects binding properties of building material and facilitates it´s processing.
Preparation of the mixture The procession of coherent loam into building material for rammed earth houses is in many cases the decisive factor of building efficiency.
If this step is due to time impossible we can substitute this process by mechanical procession of the loam.
Specialists were hired only to set the building on the property.
To higher mechanical, scratch and water resistance it is possible to add to the upper layer cow manure, lime or casein.

A New Structure Design Method for Improve Modular Joint Output Performance in Modular Robot Xiao Li1,a, Hanxu Sun2,b, Yingwen Tang2,c, Jingzhou Song2,d 1School of Mechanical Engineering and Automation, Beihang University, in China 2School of Automation, Beijing University of Posts and Telecommunication, in China alxwishyou@163.com, bhxsun@bupt.edu.cn, c1061451674@qq.com, sjz2008@bupt.edu.cn Key words: Modular robot joint, Structure design, Joint output torque.
Because the structure of module is simple and the similar module has same properties, we just need to make some simple modules to form the complete robot system, the manufacturing cost is low.
Because each module of robot is designed as simple structure, a single module has high stability, additionally, each module in the whole system can realize limited function and has limited influence to the system’s performance, which means the system will not be affected too much and can continue its work even if some modules fails.
The theoretical power consumption is .Take the power factor as 2, then the power of electric machinery is .

In addition, the FSW (Friction Stir Welding) has the better mechanical properties than base material due to formation of fine grain structure in stir zone and slightly lower corrosion resistance in a part of the stir zone and HAZ (Heat Affected Zone).
During the operating service of Inconel alloy, two domain factors, named CE (Cavitation Erosion) and JIE (Jet Impingement Erosion), up to component lifetime.

Properties of clay bricks.
Both types are bi-component epoxy resin but they are characterized by different mixing ratios, mechanical properties (tensile strength and elastic modulus) and, in particular, by different values of the density: 1,08±0,05kg/l for FIDSATURANT HM and 1,65±0,05kg/l for FIDPUTTY.
FIDPUTTY presents a consistence similar to the cementitious grout but with much better mechanical properties.
In particular, as already discussed in the previous sections, the characteristics of the adhesive, together with some properties of the support (porosity, roughness, etc.), affect the strengthening/support interface layer.
First, it has been observed that in the case of SRPs with medium density adhesives, as well as SRGs, differently from SRPs with low density adhesives, the bond resistance is not significantly influenced by the mechanical properties of the support.

But there are still some problems about dry cutting Nickel-based superalloy, one of them is the high force and temperature in cutting zone which negatively affects tool life.

In this study, the experiments were proposed in single-factor method, the effects of water vapor on cutting process with the change of milling speed (vc) , the depth of cut(ap), and feed per tooth (fz) were researched.
The cutting experimental study was proposed in single-factor method in milling GH4169.

Non-contact measurement will not affect the test results, but on account of the space limitations, the high test targets surface, and the high price of such sensors or other reasons, the use of non-contact mode testing is limited.

Among these forming factors the material properties have a great influence on the formability of the product.
Several studies concerning the determination of properties for tubular materials have been reported in literature [6-8].
The effects of friction and material properties on formability of tubes were shown in their study.
The mechanical properties of the tube are listed in Table 2.

Marchetto et al. have proved that when two surface sliding, the phonon in the form of mechanical waves transmitting along the surface formed the physical resistance of the interface sliding [4].
In addition, there are many factors which affect the friction on micro and nano scale.
The results indicate that the normal load affects the friction behavior on the micro scale, and also reveal that under high load, the micro friction could change to the macro friction.

TiO2 is one of the semiconductors that meets the criteria as a photoanode material in DSSC because it has good optical and electronic properties [8].
Nanofiber structures have attracted attention in research because of their high surface area, porous structure with good physical and mechanical properties [9,10].
The morphology and diameter of the resulting nanofibers depend on polymer properties and process parameters, including polymer molecular weight, solvent, applied voltage, solution viscosity, needle diameter, and needle tip distance to collector [11,12].
The characteristics of TiO2 nanofibers produced in this experiment were tested using a Scanning Electron Microscope (SEM) to determine the morphology, X-Ray Diffraction (XRD) to determine the phase and crystal structure, and UV-Vis spectroscopy to obtain optical properties of the sample.
This is because the applied voltage can affect several factors such as the mass of polymer coming out of the needle tip, the degree of elongation of the beam by electric force, the morphology of the beam (single or multiple jets), etc [15].
