It can be seen that the fitted curves basically agree with experimental data.
After the cooling measures are implemented, the volume of concrete begins to contract for the reason of temperature reduction, then the stress compensation effect of MgO begins to appear.
It is found that the stress on the surface of the dam has a tendency of reduction with the amount of MgO increasing, but the compensation effect is not obvious.

After the reduction available: (3) According to the equation(2) with equation(3): The voltage value Control system The most important technology of assembly machine is to provide a stable torque for the piezoelectric transducer nut so that it can complete the installation, because the stepping motor has the characteristics which working status is not easily affected by various interference factors, angular displacement is proportional to the input pulse number strictly, motor running without accumulated error after a week, fast dynamic response, easy to stop[4],the system selects the stepper motor.
After assembling, TH2818 impedance analyzer and multimeter gets the data in table 1 Table 1 Compared with the new assembly and assembled of piezoelectric transducer Resonant frequency[kHz] Impedance[Ω] Static capacitance[nF] Assembled piezoelectric transducer 19.35 14.89 11.06 New assembly piezoelectric transducer 19.63 8.64 10.65 As shown in table 1 , the assembled piezoelectric transducer’s resonant frequency is less than that of the first assembly piezoelectric transducer, piezoelectric transducer’s impedance is greater than that of the first assembly.Therefore, it can be worked out that if piezoelectric transducer assembles twice, there will be a significant reduction performance.

This is further confirmed by the tensile modulus data of CNT-NR nanocomposites (Fig. 5).
Like carbon black, CNT also reinforces the rubber matrix and helps in attaining the reduction in wear rate, but at lesser weight fraction of reinforcement.
Similar reduction in wear rate was observed during incorporation of nanoparticle by other researchers [5].

Load-displacement relations were then obtained from the experimental data, and Jin and Jf were calculated using the following formulae: )( aWB U J in in − = η and )( aWB U J f f − = (1) where Uin and Uf are the critical energy at crack initiation and the total energy dissipated from the crack initiation to complete fracture, respectively.
These voids cause local stress concentration in the surrounding regions, resulting in the reduction of the initiation toughness.
Those kinds of voids dramatically decrease due to the LTI addition (Fig.4(b) and (d)), as a result of the reduction of PCL spherulites formation corresponding to the improvement of immiscibility between PLA and PCL.

In addition, the continuous reduction in selling price of PDPs, ~ 20% annually, led to a rapid expansion of the PDP TV market.
The first stage of weight reduction corresponds to the evaporation of solvents and the second stage corresponds to the evaporation of oligomers and cross-linked monomer used in the paste.
TG data of UV Curable Paste Based on these results, the trasnsferred barrier ribs molded on glass substrate were heated to 260o C and 400 o C, respectively and their microstructures were observed.

The total reduction in area after 21 passes was 99.90% that corresponded to an equivalent strain (ε) of 6.9.
The ARB is a kind of SPD processes using rolling deformation, and the details of the ARB process have been reported in previous literatures [3,5-9]. 50% reduction in thickness per ARB cycle was used for roll-bonding at room temperature, in order to fabricate sheet materials 1 mm thick.
[10] K.Hanazaki: unpublished data.

Current density contour maps was constructed by potentiodynamic polarization data, and Fig. 3 shows the result from the unbuffered physiological solution at 37 o C.
It may be also considered from these results that hydrolysis reaction of dissolved Ti(III) ion would produce local pH reductions in a pit, which would accelerate the pit growth.
It may be concluded from the results that hydrolysis reaction of dissolved Ti(III) ion would produce local pH reductions in a pit, which would accelerate the pit growth.

This indicator data can be gained through research.
For the environment, we select the reduction of carbon dioxide, sulfur dioxide, nitrogen oxide emissions and effectiveness as representative indexes.
Suppose reduction of one ton of nitrogen oxide is 4,500 Yuan per ton, the formation environmental benefit is 0.033 million Yuan due to DSM.

On the contrary, the erosion kinetic energy will be decreased with a reduction in the particle size and the removal mechanism of the eroded surface is ductile erosion.

=0.3 =0.2 =0.5 =0.4 Fig.1 Influence of deformation temperature on flow stress Relationship between deformation degree and deformation resistance was established according to experimental data and shown in Fig.2.
With reduction of deformation temperature, deformation resistance shows downtrend on two-phase region.
This is different from ordinary carbon steel whose deformation resistance increases with reduction of deformation temperature
