The nature of an electrolyte used for aluminium anodising is a key factor which determines the type of oxides grown on the surface [1].
It was reported that some mixed acid and organic acid as anodising electrolytes can decrease the film dissolution rate, then increase the film formation efficiency and improve the film properties [6].
Since the AAO membrane characteristic were affected by anodising voltage, the controlling of the anodising voltage is essential in order to gain desired characteristic of AAO membrane for specific purpose [9].

When fluorine atomic substituted the hydrogen of Siloxane methyl, fluorine atoms and carbon atoms bonded strongly, thereby fluoroalkyl played a "shielding" role on Si-O main chain, and blocked the influence of external factors.
By adjusting the length and proportion of "soft segment" and "hard segment", the hydrophobic / oleophobiccan can be adjusted, but the hydrophobic properties is not affected, when the silicone content increased.
They found hydrophobic properties of the copolymer is not affected by silicone and the composition of fluoropolymer surface.
Other characters Introduce polydimethylsiloxane to other polymers can improve the polymers’ performance of mechanical properties, thermal stability and so.
Baysal [22] studied the mechanical properties of PDMS-b-PS copolymer, when the content of PDMS in copolymer is 12% to 18%, the mechanical properties of the new copolymer is different from PS homopolymer.

Introduction One of the key factors affecting gear drive dynamic property is the tooth profile.

The dimensions of the deformed head in electromagnetic riveting will depend on several factors, including the specific application and the desired result.
Effect of locking mode on mechanical properties and failure behavior of CFRP/Al electromagnetic riveted joint.

Introduction The behavior of grain boundaries with regard to their response to applied forces can be crucial for the mechanical properties of crystalline materials.
As known [1-10], boundary migration caused by an applied mechanical stress can result in a shear strain of the crystal region behind the moving boundary.
(a) Misorientation dependence of measured (points) and calculated (lines) coupling factors for <100> symmetrical tilt grain boundaries and (b) activation enthalpy H of stress induced migration of these boundaries [17].
The obtained coupling factors, however, were found to deviate from the coupling factor calculated according to the tangent rule (Fig. 3).
An increase of the migration activation energy with rising impurity concentration suggests that the migration mechanism is substantially affected by the solute segregation.

The reasonable cable force is the key factor for the safe use of cable-stayed bridge.
Introduction Since the 20th Century, the cable-stayed bridge obtained rapid development at home and abroad with its appealing design, great mechanical behavior and long spanning capacity, etc.
Cable-stayed bridge has complexity mechanical behavior as a high-order hyper-static structure.
As the main load-bearing structure, whether the reasonable of cable force directly affect the safety, serviceability and durability of structures in completed and used stage.
Method of continuous beam on rigid supports: Under the status of the completed bridge, the internal force of the mechanical properties of cable-stayed bridge girder as same as the continuous beam with rigid supports.

Introduction The study and development about the residence is very necessary because it is the Basic factor of human.
They affect for the heat transmission into the house so there is legislation for control the total heat transfer of the office building, academy.
Another method in the reducing temperature of the house and building is selection of the good material with thermal protection properties such as Radiant barrier.
Moreover, under the air gap has the Phase change material, it affects to the heat absorbed for energy storage before transition.
After the heat transition, it was stored by properties of the Phase change material used [4-5].

It is reported that the mechanical properties such as yield strength, ultimate tensile strength and elastic modulus increase with increase in filler content while ductility decrease with the addition Ti reinforced in alloy matrix.
The input control factors and there values are listed in Table 2.

By designing fuzzy adaptive controller to adjust the scale factors of speed and position controller in time, ensure the robustness of a single suspension system.
This not synchronization suspension will arouse mechanical couple, it will affects the quality of work-piece, in severely, the work-piece may be scraped.
It will lead to beam tilt, affects machining accuracy.
For the output response, due to the structural properties of the system is symmetrical, the role of system structure for each output response is the same.

However, extreme weather conditions (high temperatures and humidity or intense cold) may place too much stress on the thermoregulation mechanism, also reducing the wearer’s physical performance [8], affecting health and even endangering life through hypothermia and hyperthermia.
These are the main factors affecting thermophysiological comfort, as well as physical and mechanical characteristics (e.g. abrasion resistance and dimensional stability).
