The properties of the gel were subsequently investigated by DSC, UV-vis, and gravimetry.
In all the stimulus factors, light has been taken into account as an external stimulus to induce the phase separation because of its ready accessibility and chemical purity.
The properties of the hydrogel were subsequently studied carefully.
The studies result showed that a small amount of M was enough to make the gel light-sensitive, which will obviously less affect the main properties attributed to NIPAm units of the gels.

Studies show that it affects large extent the performance of material when the banded structure serious and uneven distribution.
A lot of plastic inclusions which mostly are sulfide and silicate, long strip of inclusion similar to the tip in tablets, and the distribution chain in the intensive band ferrite, at the same time, the long strip of inclusions reduce the transverse properties of steel dramatically [1].
The distribution of which inclusions and the cracks is about perpendicular is the main reason for crack formation and affect the uniformity of transverse mechanical properties when the steel cold-bend.
A large number of tests and research have proved that [2 ~ 4]: The performance of steel is greatly affected on non-metallic inclusions.
This sulfide accumulation is an important factor causing cracking of steel.

However, in the actual process of service, the failure distribution of VDMOS are not only affected by the failure modes, the failure mechanisms and the structures of device, but also by the sustained stress, its working environment and many other factors.
And, vibration has become a key factor affecting the reliability of electronic products in the areas of aerospace and military.
The beginning location of failure is found from these experiments, then evaluating the property of resist and the ability of work for the device during the changes of temperature.
When the device is used in actual environment, the stress value on the boundary of the chip and the bonding layer and the location of the external pin is bigger than the result of simulation, it can be effected not only the frequencies but also other factors[5].

The effect of different parameters during thermo-mechanical processing on the earing behavior of AA3003 aluminum sheets has been investigated.
This thermo-mechanical treatment which involves both cold plastic deformation and recrystallization, results in sheets with anisotropic mechanical properties.
These thermo-mechanical treatments, along with the composition of the alloy, determine the crystallographic texture which is believed to be the most important factor affecting the earing behavior of the material [2-4].
In addition to the rolling and annealing operations, homogenization of the cast material is generally considered as an important step which can also affect the earing behavior [11,12].

Analysis of causes and mechanism for the rapid floor heave The main factors of floor heave based on similar simulation experiment obtained by Jiang Yao-dong et. are floor rock, rock stress, water, and support strength [4~6].
Of course, for the rapid floor heave, we should do for the prevention: (1) Strengthen the underground geological prospecting, probe the detailed litho logy and structure of roof and floor, change the mechanical properties of rock and improve the strength of surrounding rock.
(2) The causes on rapid floor heave are mainly four factors including the weakening of surrounding, affect by the stress concentration, affect by the gas pressure and floor water pressure rock, and affect of support situation and so on
Therefore, high stress, soft surrounding rock, bad effect of water, the additive effect of influence to mine and supporting pressure and other factors were superimposed on varying degrees for speeding to floor heave, thus rapid floor heave is occurred

Si eutectic and dendrite α-Al in the composites was finer than unreinforced, therefore these finer phases in composites was also contributed to increase mechanical properties of AMC such as tensile strength, hardness and wear resistance in addition to good weeting between Al alloy and Al2O3 (see figure 6 as below).
Mechanical properties of AMC with 12,5Vf% Al2O3.
In addition to the nature of Al2O3p is hard, the hardness increased due to some theoretical factors such as residual elastic stress as well as high dislocation density due to particles reinforced, and decrease in grain size or sub grain of the matrix[11].
This is also assosiated with higher hardness and good wetting between matrix and Al2O3p reinforcement since wetting constituted the most important role in mechanical properties of MMCs.
Mechanical properties of Unreinforced and AMC with 12.5Vf% Al2O3p.

Crack initiation, wear and failure are caused by mechanical fatigue as local stresses in the contact area are high.
Using three uni-dimensional sensors in the microscope allowed finding a strong correlation between the magnetic field and the stress intensity factors during crack growth.
It was found that the magnetic field intensity is affected by the magnetization direction as well as the magnetization location.
Tables 2(a) and 2(b) present their mechanical properties.
Mechanical properties of the specimens: (a) Silicon nitride ball, TSN-03.

As a result, Fe – Gt : N = 1:3 catalyst had the greatest electrochemical properties which is identified by the large area of CV curve.
The Fe, Ni, Co and Mn are 3d-transition metals which can enhance the intrinsic activity by 2-4 times due to a change in morphology, electronic properties, inhibition towards anion adsorption and surface sensitive factors [8].
Furthermore, electrochemical and physical properties were characterized.
Summary Various carbon and nitrogen ratio of catalysts have different electrochemical properties and particles morphology.
Fe2O3 and Fe3C have important role to improve the electrochemical properties.

Introduction SiCp/Al composite is reinforced by the second phase characteristics of silicon carbide particles, and it is enormously used in aerospace, electronics and automobile industries due to its superior properties such as higher strength to weight ratio, excellent low-temperature performance, chemical inertness, high strength and wear resistance.
Tool corner radius is one of key factors which can influence residual stress, cutting force and temperature in the machining process.
To analyze effect of tool corner radius on the machining process, single factor simulations would be carried on.

Catalyst surface area directly affects catalytic activity.
Mechanical Strength Parameters.
There are 3 indicators for mechanical strength parameters: axial mechanical strength, transverse axial mechanical strength and wear rate.
The pressure drop should be as small as possible, otherwise it will directly affect the hosts of the boiler and flue gas fan safely running.
Thus It also become the key factors that restrict the development of catalysts in China.
