During CT-scans, heating inside the cabinet and varying environmental conditions may affect the position of the focal spot and distort the manipulator system, leading to relative displacement of X-ray projections and distortions in the reconstructed 3D image.
The turntable was positioned as close as possible to the X-ray tube resulting in a magnification factor of m = 13.6.
Extraction of the circumferential line from the reconstructed volume To investigate the geometrical properties of the extracted circumferential line, an integrated graphical analysis [8,9] was carried out.

The diffusion layer of such an interface, will on one hand, increase the property of the composite material, and on the other hand, cause some deterioration of properties.
Such composite material needs to have not only good composite strength, but also good electrical conductivity and mechanical properties.
However, the diffusion heat treatment will cause the diffusion layer to appear, and it has a multiple copper aluminum inter-metallic compounds, that will affect the strength of binding and the electrical property [4].

The reduction of chromium (Cr(VI)) ions by both of PVA/CS/(nano and micro)-SiO2) beads, as evaluated by the reduction duration taken were studied by photocatalytic process in which factors of SiO2 powders size and pH of reducing environment were varied.
Glutaraldehyde serves as chemical modification/cross-linking agent that increases the reduction properties while preventing the dissolution of CS in strong acids and improving the mechanical strength of CS [18-21].
Thus, this supports the better performance of PVA/CS/nano-SiO2 beads in photocatalytic properties.

In order to research the changes of concrete properties in freeze-thaw environment, five concrete samples with water-cement ratio respectively equal to 0.60, 0.65, 0.70, 0.75 and 0.80 were tested in freeze-thaw environment according to GB/T50082-2009 concrete rapid freeze-thaw cycles test method.
In this paper, we will emphasize the deterioration of the basic mechanical characteristics of concrete under freeze-thaw circumstances through freeze-thaw cycle experiments on concrete.
Under the same circumstances except for the water-cement ratio, equal amount of calcium hydroxide will be produced and the deterministic factor of the anti-carbonation of concrete is the spread of carbon dioxide.
One of the important factors that affect the concrete structure is water-cement ratio.

The material removal mechanism of the EDM process is not regulated by mechanical force, so the machining characteristics of the EDM process are not governed by the mechanical properties of the work piece material.
The machining parameters of EDM are many, so conducting conventional single-factor experiments to reveal the effects of all of them on EDM performance is expensive and time-consuming.
From the designed matrix based on CCD It was observed that discharge current, pulse duration, pause time and discharge voltage speed are the significant factors, which affect MRR and Ra.
For MRR, most significant two-factor interaction effects were present among pulse current and pulse on time, pulse current and off time, pulse on time and off time and pulse-on time and discharge voltage.
However most significant two-factor interactions were pulse current and off time, and pulse current and discharge voltage.

Due to desirable characteristics of mechanical properties and biocompatibility, Ti and its alloys are widely used as implants embedded in the human body [2].
The surface morphology, energy, roughness, surface hydrophilicity, surface chemical composition and surface wettability of implant are considered as the main factors that affect the biocompatibility of implants [4].
The factors that affect the biocompatibility of implant include the surface morphology, surface roughness, chemical composition and wettability of the implant surface [17].

It makes sense to expand the area of using the unique properties of these materials in mechanical engineering, particularly, in the manufacture of welded metal structures.
This is due to the peculiarities of its physicochemical properties [18, 20].
Investigation of the Technological Properties of the Protective Coating The behavior of the protection coat at heating was investigated using an OD-103 derivatograph, and the end products of pyrolysis were studied on a GACH-21.3 chromatograph.
The use of the developed protection coat allows to increase the efficiency of the open arc welding, to improve the surface quality and to ensure the preservation of the metallic structures specified mechanical properties, to eliminate the formation of local stress concentrators in the surface layer and, thereby, to eliminate the need to introduce additional technological operations for cleaning and grinding the surface.

., meanwhile, the preparation conditions as well as adsorption property of the fiber for precious metal ions were researched.
The paper investigated the effect produced by solvent, molar ratio of reagent, reaction time, pH, etc. on reaction products, meanwhile the structure and property of the functional fiber were characterized by the means of IR, EA, TG, gravimetric analysis[8], etc..
The reactive mode is inferred as follows [6,7]: ①Crosslinking In order to make the obtained modified fiber maintain certain mechanical strength and good antisolvent performance in the fabric processing and use-regeneration recycling process, we used ethylene glycol as solvent, and successively selected hydrazine hydrate, ethylenediamine, and DETA as crosslinking agent to crosslink the raw material PANF.
Factors Affecting the Reaction Effects of PH on the reaction Table 2 Effect of pH value on thioanidization process pH the Rate of Fiber Liveweight Growth Sulphur Content 7.5-8.0 30.75% 21.6% >8.5 55% 0.18% The data in Table 2 showed that: in the preparation process of the modified fiber, the most favorable condition for the formation of sulfamide functional group was when pH of the reaction solution reached 7.5 ~ 8.
This was mainly due to the fact that under alkaline conditions, -CN or the generated sulfamide group hydrolyzed and generated -COONa, so the pH value of solution in the reaction process was one of the key factors inhibiting by-products of hydrolyzation.

Then the mix solution was poured into a 3-neck flask with a mechanical stirrer and a condenser, which was placed in a thermostat water bath.

So, kaolin and crosslinker affects water absorbency of material more than neutralization does.
But these are just assumptions based on some researches, and the real mechanism needs further study of its components, structure and other factors.
