Qiu et al. treated ST using the absorbent of Clinoptilolite (11.2) [8,9].
The effect of initial pH value of aqueous solution on ST degradation Fig.6 The residual concentration of the ST Fig.7 The Y of the ST with time with time ( gas gap=5mm, needle naked) ( gas gap=5 mm, needle naked) Figure 6 suggests that the degradation rate of ST is faster in alkalinity and acid media than in the neutral condition, which is the same with the report by Gai el al. [11] report.
Xue el al.[12] and Huang el al.[13] have the same results in their experiments.

According to Ghani et al. [7], a reduction in cutting force (i.e. higher cutting speed) leads to the formation of less surface roughness.
· Cavity: According to El-Wardany et al. [14], when the tool wear progressed, surface metal was displaced in the direction opposite to the feed mark ridges.
However, Sharman et al. [15] believed that the formation of surface cavities was associated with carbide particles.

The El Centro earthquake accleration with the scaled magnitude of 400 gal is assumed to apply on the simulated structure.
When the structure is subjected to El Centro earthquakes, the effect of the displacement contol outweighs the acceleration control.

These alloys are AA2024-T3 (Al-Cu) and AA2099-T8E77 (Al-Cu-Li) and are both in the plate format.
Ma et al [6] did, however, observe that Li sat with Al-Cu-Mn dispersoids (~1 µm x 200 nm).
Ma et al [6] also showed that nanometre sized Al-Cu-Mn-Li dispersoids were also linked to the propagation of the pitting corrosion.

Wang et al [5] studied the role of the terminal mass on the fretting and fatigue parameters of the hoisting rope in the transition segment during a lifting cycle.
Urchegui et al [7] analyzed the evolution of the wear on the number of cycles and the effect of the diameter of the pulley in the preferential sites of wear.
Petit et al [8] studied the propagation of fatigue cracks in thin wires, and performed fatigue crack growth experiments.

Following AFRP, CFRP and GFRP provides better performance when compared with LCS and Al 6061 T6 based on MSS value.
Similarly, metallic pressure vessels LCS and Al 6061 T6 are also analyzed.
Conclusion The FE analysis of AFRP, CFRP, GFRP composites along with LCS and Al 6061 T6 metallic pressure vessels are carried out in the present study.

Given that properties such as sY, El and K1c are only poorly predicted by this model, one would wonder whether properties of Group 1 can be used as input to predict them.
In this sense, Zr and Al play a central role in grain size reduction from 1000 μm in pure Mg to 50-100 μm, when Zr (up to 1 at%) or Al (up to 12 at%) are added.

In order to simulate the seismic response of deep-soft soil sites as possible, the calculation selected 2 ground motion: predominant frequency components are based on the 0.2-0.4s El-centro and the 0.3-0.8s Qianan seismic waves.
Fig. 3 Response spectra of inputting El-centro motion Fig.4 Response spectra of inputting Qianan motion As we can see from Figure3&4, in terms of El-centro wave whose frequency component is more complex, input seismic motion period (0.4~1s) obviously larger partly, but acceleration response spectra caused by shear-wave velocity standard deviation is not obvious.

HR700LA steels have the largest TS and YS with the smallest EL.
A larger TS and smaller EL combination couples larger springback angles, exhibiting much greater springback behaviour of the steels.
That is to say, larger TS with low EL is harmful to shape stability of the steel.
Oppositely, smaller TS and larger EL combination is helpful to shape stability.
