In the computational models, the stress distribution in the depth direction of the TBCs and also the influence of mechanical properties in heating, dwelling and cooling thermal cycles, were investigated.
Material behavior and properties.
Physical properties of different layers at different temperature refer to the reference [3].

It shows that failure usually occurs in the cooling stage, because the creep is less affected at this time.

Waviness has little effect on thin composite materials while greatly affects properties of the large and thick composite structures [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12].
Only one review upon effect of fibre waviness on the mechanical properties of unidirectional fibre composites has been finished by Piggott since 1995 [12].
In fact, these factors related with both waviness geometry and attribute are challenging for any manufacture method, seen in the following section.
Effect of Waviness on Properties of Composite Materials Effect of Waviness on Mechanical Performances Effect of waviness on mechanical performances was performed by many researchers [1, 3, 4, 5, 7, 8, 9, 12, 14, 15, 33].

Influence of Complex Frictional Heating and Mechanical Stress Effect for Surface Crystalline Structure Change of Zirconia Femoral Head Masaru Ueno a , Mikio Iwamoto b and Junji Ikeda c Japan Medical Materials Corporation, Uemura Nissei Bldg. 9F 3-3-31 Miyahara, Yodogawa-ku, Osaka 532-0003 Japan a uenom@jmmc.jp, biwamotom@jmmc.jp, cikedaj@jmmc.jp Keywords: Zirconia, Phase Transformation, Wear, Hip simulator Abstract: Several clinical reports pointed out that the monoclinic transformation of crystalline structure of zirconia femoral head with clinical service time can cause the changes of surface roughness and mechanical properties.
On the other side of these desirable properties of zirconia heads for THP, transformation of the surface crystalline structure and mechanical degradation of zirconia heads were sometimes reported as the possible cause of clinical failure of zirconia THP system.
Y-TZP has been used for femoral head replacement due to the good mechanical properties and excellent biocompatibility.
As mentioned above, the phase transformation characteristics would be affected by not only temperature but also mechanical stress.
Conclusion We found that surface degradation of zirconia would be accelerated by hip simulator motion and mechanical stress effect would act as an important factor as much as surrounding temperature or frictional heating.

But if the element has similar chemical properties or ionic structures, it can also be absorbed.
Table 2 lists the reported bio-sorbent used for precious metal adsorption at home and abroad. 3.4 Factors affecting the bio-sorption Bio-sorption process is affected by many factors, such as types of bio-sorbents, the type of adsorbed metal ions, pH, temperature, adsorption time, competing ions and solid-liquid ratio, among which pH, temperature, adsorption time and the number and type of competing ions have the biggest influence [10]. 3.4.1 pH of the solution For most adsorption processes, pH of the system can determine the adsorption capacity.
Within a certain range, the temperature has some influence on the adsorption capacity, but not as influential as pH. 3.4.3 Adsorption time Adsorption time is an important factor affecting the efficiency of adsorption of heavy metals.
Normally, competing ions may compete with target ions in binding to the adsorption sites, or reduce properties of adsorbent [13]. 3.5 The application of bio-sorption in wastewater treatment Yan Keliang et al [14] used white rot fungi to bleach the dye via adsorption.

Finally, the sound absorption coefficient and mechanical properties of the samples were examined.
It can be seen that the incorporation of expanded perlite is detrimental to the improvement of the mechanical properties of the material.
After mixed with the material, it can absorb the water affecting its workability and thereby the strength will be decreased[2].
Therefore, admixtures should be not only selected from the perspective of improving the absorption properties and overall factors should be taken into consideration. 3.1.3 Microstructure analysis Fig. 4 shows the pore morphology of expanded perlite and ceramic within the samples observed by SEM.
From the figure, it can be seen that, the sample with foaming agent has most significant sound absorption property at the trough of the absorption coefficient curve for the material. 3.3.2 Mechanical properties Fig. 12 shows the bending strength and compressive strength of the above-mentioned two samples on the 28th day.

To investigate the possible effects of the curing temperature on the mechanical properties of the Hysol 9466, two test series for this adhesive have been carried out.
The static tests for the two different kinds of curing of Hysol 9466 give the same elastic properties (elastic modulus E ≈ 1.99 GPa and proof stress Rp0.2 ≈ 52 MPa).
Dynamic scale factor - compression tests.

The advantage of these fibers is that their properties can be adapted to the final purpose of use [1].
The present work is to investigate the effect of thermal treatment conditions on the morphological structure, physical and mechanical properties of PorelTM fiber.
Effect of treatment time on the properties of fabric.
In order to protect wearability and mechanical properties of PorelTM fiber knitted fabric, the thermal treatment time required to be no more than 90s when the treatment temperature was kept at 140°C.
It maybe explained that the damage on mechanical properties of PorelTM fiber gradually increased with the increase in temperature during thermal treatment process, especially at high temperature.

Besides, temperature and stress intensity also have great effect on the performance of material and the fracture properties of material.
Superplastic is the important properties of TiAl alloys, so the effect that grain boundary sliding have on TiAl alloys is also can’t be ignored.
Apart from the factors mentioned above, there are still have many other factors influencing the performance of materials, such as the temperature, the size of grain, loading frequency and stress intensity, etc.

This paper reports the fabrication of a tunable radio-frequency (RF) inductor and discusses the parameters that influence the quality factor (Q) of the inductor.
Fig. 1 The structure of the inductor Theoretic Analysis The main factor that affects the Q value of the inductor is the large loss caused by various devices’ parasitic effects, which can be expressed by certain equivalent components, as shown in figure 2.
When micro mechanical method is adopted to remove the substrate under the inductor and form suspension structure, all the parasitic components , Csub, Rsub and Rse can be ingored.
For the inductor which is applied in the RF communication, skin effect of conductors will dramatically change conductive properties of conductors with the rise of frequency.
