Fig.1 350-meter-high television mast The initial impact of guyed mast structure parameters on Impact of changes in inclination tow rope on the mechanical properties of the mast structure According to the towering structure design specifications, tow rope diagonally arranged inclination generally within the range of 30 ° ~ 60 °.
Here's to 350m television mast, for example, when the tow rope inclination to study the changes affect the mechanical properties of the structure.
Cordelle layers under the influence of the performance of the mast According to the towering structure design manual, tow rope-level layout depends on many factors, in addition to the mast height, shaft interlayer spacing, but also taking into account the structural stability, structure installation and use conditions.
Based on the slenderness ratio is allowed to change the number of layers in the range of tow rope, to study the effects on the mechanical properties of the entire structure.
The various factors are reflected in the above text.

Introduction Advanced ceramic is one of the dominant materials used widely in modern industry, due to its outstanding mechanical and physical properties like high thermal resistance, high hardness and chemical stability.
Photo of UV curing system Hardness and Abrasion The hardness of lapping plate is one of the key factors because the lapping plate undergoes load and produce deformation during the lapping process.
The certain hardness of the lapping plate may keep the grain in the situation of scraping or rolling, thereby affecting the material removal rate and surface roughness of the woke-piece.
Furthermore their wearing properties were compared by lapping those samples under the same machining conditions and then measuring the loss of thickness of the samples.

The paper deals with the influence of climatic factors on selected properties of remedial plaster.
A number of properties have been already tested and certified (WTA Guidelines).
It turns out that some of the properties of remedial plasters are influenced significantly by climatic factors.
The evaluation of water absorption by immersion and in a vacuum was carried out without drying between both tests, so the hydrophobic properties of the plasters were not affected by drying process. 2.

Consolidation and Mechanical Properties of Gas Atomized Al-Si Powder Y.J.
Introduction High strength aluminum alloys have been used for automobile, sport goods, electrics and aerospace applications because of their lightness and good mechanical properties [1].
Their mechanical properties have been improved by addition of alloying elements such as copper, magnesium, zinc and silicon, etc.
The mechanical properties of the Al-Si alloys are dependent on volume fraction and size of primary Si particles.
The UTS mechanical properties of 450MPa were much higher than that of conventional hypoeutectic Al-Si alloys.

Through the thorough research, the basic theory of fully mechanized top-coal caving will be consummated, the stability and reliability of the system will be worked over by systems engineering, and the complex problems of equipment-selection and surround rock-displace which involved of many factors will be resolved.
At the same time, surrounding rock movement [1] and ancillary equipment and many other complex issues involving multiple factors can be solved. 1 Definition of fully-mechanized top-coal caving mining system Fully-mechanized top-coal caving mining system means a dynamic complex systems composed by face production systems, transportation and drainage and production auxiliary systems as well as the surrounding rock, supporting and its engineering geology, natural environment.
Excitation of the system (input) and response (output) is not a simple proportional relationship, but a very complex nonlinear mechanical relationship.
Thereby affecting the stability and reliability of the system.
Steady state parameters may vary with the parameters of the original state, but will not affect the overall performance of the system and structure.

Metallurgical factors of γ gamma phase microstructure development strongly depend on welding configuration, and heat input is not as important as welding configuration.
The theoretical methodology is reproducible as consequence of availability of thermodynamic and kinetic properties of Nickel-based or Iron-based single-crystal superalloys.
Mechanical and metallurgical properties are renewed by widespread application of laser welding repair technology to easily diminish serious weld defects and rejuvenate damage parts because of excellent reparability.
These are additional contributing factors to degradation-resistant microstructure melioration.

Introduction The analysis for field-aged asphalt mixtures is complex because there are some factors can affect it like the air voids, temperatures, construction method which cannot be controlled by researchers.
The direct tension test is an efficient way to obtain the undamaged viscoelastic properties like complex modulus especially for the field-aged asphalt layers.

Schematic circulation system of synthetic seawater for fatigue test It has been recognized that the fatigue strength of steel in a corrosion environment is significantly affected by the fatigue loading speed.
That means that other factors, for example, the formation of the rust, electrocoating, stress concentration of the pit at the tip of the crack, corrosive dissolution etc. are thought to be related to the crack propagation behavior in seawater condition.
