With the increase of KH-560 content, two key factors (surface microstructure and low surface energy) contributing to the superhydrophobicity of the coating layers did not change greatly, so the difference in KH-560 content had little effect on the super hydrophobicity of the coating.
However, the ratio significantly changed the mechanical stability of the superhydrophobic coating.
And the results showed that the method could improve the mechanical stability effectively, and the different coupling agent content had great influence on the mechanical stability of the superhydrophobic surface.
As can be seen from the above, the sol-gel process was simple, low cost, and theprepared superhydrophobic coating had godd hydrophobicity and mechanical properties.

Extension of the segment is mainly affected by the interaction of seam and charge welding phenomena and, nowadays, its prediction is still a tricky task involving rough empirical relations or labour intensive analyses.
The seam weld usually is characterized by high mechanical proprieties because it is a solid state junction generated at high hydrostatic pressure under oxide-free conditions, even if of lower properties respect to the base material.

As previously stated, Altair HyperXrude® uses an Arbitrary Lagrange-Eulerian (ALE) description of motion in problems with moving boundaries since it coalesces a good numerical stability and convergence properties with a robust mesh moving technique.

Surface passivation is an important for III-V materials to remove surface state for achieving optical and electrical properties.
In 1987, Sandroff reported a sulfide surface passivation of GaAs to improve the performance of electronic properties [1].
However, after the passivation by (NH4)2S solution, the thick S layers can be formed, and affect the luminescence property.
Meanwhile, Al2O3 film has good mechanical properties, which can be more effective protection devices.
The Optical properties and surface morphology of the treatments on InP is investigated by PL, XPS and AFM measurement.

Nevertheless, PM parts are limited in terms of the shape complexity and production efficiency, not to mention the poor mechanical properties and corrosion resistance caused by large porosity and density gradients.
This process allows the production of more uniform microstructures and improvement of mechanical properties.
While, for sintered 316L SS, mechanical properties and microstructure were the major of concerns.
Castro et al compared the corrosion properties of 316L SS produced by MIM, wrought and conventional [8].
Muterlle et al [9] investigated the mechanical properties and corrosion resistance of MIM 316L SS containing delta ferrite.

Gutfinger et al.P[7]P studied the problem of solidification of polymer melts with variable physical properties for non-Newtonian flow between two plates, held at a constant temperature, by means of a combination of a finite element method coupled with conventional numerical methods.
The influences of these factors on the phase changes and heat transfer in the die are analyzed.

Figure 12 illustrates that the inlet temperature of the polymer greatly affects its phase change.
The boundary conditions of heat transfer all affect the temperature of the die and the phase change of the polymer.

Perform a numerical simulation for the original roadway support, base on the in-situ stress and physical and mechanical characteristics of surrounding rock in experimental; study the impact of the stability of roadway’s surrounding rock, while the space change of trellis and change of supporting intensity; optimizing the original support form, so as to maximum reducing the impact of the coal bumps.
There are many factors impact could result in coal bumps, such as hard coal seam, hard roof and floor, geological structure, additional stress with mining, mining depth and area size of goaf [1].
Within the distance scope of 6.2~27.8m, affected by the mining, the internal stress of coal increased rapidly and peaked to 26.1MP at the position of 6.2m, then reduced quickly within the scope of 0~6.2m.

Introduction Liquid metal forming is to fill liquid metal into molds and cool down to normal temperature, which containing some complex factors influence to cast quality.
Actually, the casting shape, materials diversity and the nonlinearity change of material thermal property make the solidification process to be very complex.
