., but fast neutron irradiation induced brittleness is the most important factor [5-11].
And then, optical microscope (OM) is used to analyze the microstructure of the specimen with cleavage fracture, and the analysis results are compared with those of the specimen without cleavage fracture, determining the main factors causing the cleavage fracture of the specimen.

Thus, a compromise must be sought between the continuously increasing pressure drop due to dust loading and the factors (such as filtration area, filter configuration, filter thickness, and airflow velocity) that determine the dust capturing capacity of filters while maintaining the desired level of protective efficiency.
These are primarily related to the user’s field of vision, which directly affects safety.
Just as the microstructural factors in filters influence efficiency, the chemical composition of the sediments and the treatment method critically impact analytical outcomes.
Similarly, study [23] by Medved I. contributes to this interdisciplinary theme by proposing a mathematical model that links the durability of titanium alloys to cyclic mechanical loads.
In general form, the formula can be expressed as: кconfig=а∙n2-b∙n+с, (4) where a, b, and c – are coefficients which determined experimentally and depend on the properties of the filter material (hydrodynamic resistance, fiber diameter, and packing density) as well as configuration parameters (corrugation height).

PVD preparation process of (TiN + CrN) / CrAlN superhard nanocomposite multilayer coatings Jun Tian1, a, Ziqiong Shi1,b 1College of Mechanical Engineering, Dongguan University of Technology, Dongguan, 523808, China a841608534@qq.com, b569332129@qq.com Keywords: PVD technology, nano-composite multi-layer, preparation Abstract.
These coatings formed by the combination of nanolayers, and some may be too far because the physical properties of the nano-layer of different composition and the difference of the matrix, such as thermal expansion coefficient of the coating will have a greater internal stress, making the coating to break or fall off[7-8].
The Al content of CrAlN department is another important factor to affect the coating hardness and antioxidant capacity.

Because the propeller actuator is driven by the direct touch, thus the preload between the actuator and the platform will directly affect the movement features of platform.

These Mg alloys were prepared by extrusion or rolling processes and indicated excellent mechanical properties [2,3].
When a stress is loaded parallel to the basal plane, schmid factor for basal plane is negligible, kink deformation is initiated.
From these results, the kink deformation significantly affects deformation of the LPSO phase and contributes the better rollability compared with pure-Mg at room temperature.

Effects of Temperature on the Impedance of PEM Fuel Cell Qian liu1, a, Hong Sun1, Zhengnan Jin1, Lihua Luan1 1Transportation and Mechanical Engineering School, Shenyang Jianzhu University, Shenyang 110168, China aqian546000@163.com Keywords: PEM; fell cell; electrochemical impedance; temperature Abstract.Electrochemical impedance (EI) plays a very important role on the characteristics of proton exchange membrane (PEM) fuel cell.
SHANG et al. [1], GUO et al.[2] experimentally analyzed the impedance with different discharge current of the PEM fuel cell; Ma [3] found that there are marked differences of EI for the PEM fuel cells with different channels; FAN et al. [4] analyzed the typical shapes of electrochemical impedance spectrum（EIS）and calculated the polarization resistances by the equivalent circuits; YANG et al.[5] experimentally studied the EI of PEM fuel cell without external humidification, and found that the increase of ohms impedance is the main factor that caused the breakdown of the performance of PEM fuel cell; Easton et al. [6] analyzed the capacitance and ion transport properties of the catalyst layers in the PEM fuel cell; Wagner et al.[7-8] studied the effect of the concentration of CO on the EI in the PEM fuel cell; Chen [9] studied the effects the diffusion layer in the PEM fuel cell on its EI； Saeed et al. [10] studied the effects of the assembly pressure on the EI of the PEM fuel cell.
That is to say, the temperature doesn’t affect markedly the impedance of electric double layer.

As to medium-high carbon steels such as eutectoid SK5 steel, there is still less discussion about cleavage crack because of another key factor-carbide- which dominates the mechanical properties of the bainite structure in medium-high carbon steel, of course including the fracture behavior.
This also significantly affects the quality of the EBSP and our ability to determine the orientation.

This article complements other studies carried out by the authors [5, 6], underpinning the results of the physicomechanical properties of Portland cement concrete containing flat glass powder as fine aggregate.
As can be seen in this figure, the aforementioned variables affected the slump of the concrete, although the variable w/c ratio exerted the greater influence.
(c) 0% of glass, w/c=0.50 Another factor that directly influenced the slump loss in fresh concrete was the angular and lamellar geometry of the glass particles, which also decreased the fluidity.

Manual addition of salts (on metal surface) combined with mechanical stirring or stirring by porous plugs in the bottom of the furnace has also been a method for alkaline removal.
It also will affect the material properties negatively.
Effect on casthouse cost Reduction of dross generation and metal loss has always been a cost factor in the cast houses.

These results indicated that the chloride concentration was most important factor that affects the hydrates of MOC specimens.
