The advantage of this approach is a significant reduction in workload, save a lot of money.
From collect in-situ test data, we obtained on the two earthquakes earthquake liquefaction field survey data of total 358 cases, is shown in Table 2.
Since the two liquefaction data does not cover the liquefied layer thickness and thickness data, it also can not directly use these data depth examination of the applicability of norms liquefaction features.
Liquefied layer thickness statistics in history 24 earthquakes liquefaction site survey data [5], the results are shown in Table 3, obtain 110 seismic liquefaction data.
layer is less than 4.5m data accounted for 80.4%, intensity of Ⅶ degrees liquefaction layer thickness is less than 6m data accounted for 82.4%.

Although smart materials in building may contribute to energy demand reduction and be considered as innovative technology with multiple values, currently available sustainability assessment tools would not allow the adequate evaluation of smart materials in buildings.
Such design strategies include energy demand reduction from lower heat gain within the building, energy supply of energy from on-site renewables [5], and multi-functionality and higher efficiencies of resource uses [4,6].
Reduction of energy use and carbon emission is to improve the energy performance and most illustrated in smart material façade design.
Phase change materials, smart glazing, and movable solar shading are identified among the promising adaptive façade systems and components in terms of energy reduction potential [7].
Besides, self-cleaning coating made of smart materials contributes to overall reduction of environmental impact and elimination of pollutants.

(6) : the target value for neuron corresponding to input data on the output layer.First, input the input-output pair into the neural network.
We extract historical data of the aforesaid input parameters of 14 days during 2012/7/3 to 2012/7/30 as the training samples of artificial neural network.
It is observed in Figure 4 that the forecast model trained by using the historical data of the 14 days as training samples has good effect.

The mechanical data found are in good agreement with the porosity results, that is, as the porosity values increased, the mechanical resistance gradually decreased.
Geometric (apparent) density, real and porosity data for eight types of geopolymeric mortars studied.
· The mechanical results found revealed a systematic reduction of the values of maximum resistance to average uniaxial compression, with the reduction of the molar concentration of the hardening solution, used during the geopolymerization process

The data of Palladium powder and place at different cyanide concentrations, different temperature and different oxygen pressure are obtained.
A pure metal palladium place rotating disk with a 2cm diameter and high 0.4mm was used to obtain dissolution rate data.
Dissolution involves an electrochemical process in which the anodic reaction is Palladium oxidation while the cathodic reaction is oxygen reduction.
Fig.7 Effect of PO2 on percent on ratio of Pd cyanide Fig.8 Effect of PO2 on percent on ratio of Pt cyanide dissolution(NaCN 12.5 g/L,140 °C, 3 h) dissolution(NaCN 12.5 g/L,140 °C, 3 h) Conclusions For a further understanding of the behaviour of PGMs in the pressure cyanide leaching process, some new explanations are proposed in the present paper. (1)The cyanide leaching rate of Palladium powder > Palladium place appears to be related to the metal size. (2)The rate for the dissolution of Palladium in cyanide solution is with respect to O2 pressure. (3)The dissolution mechanism involves an electrochemical process in which the anodic reaction is palladium oxidation while the cathodic reaction is oxygen reduction and bonding mechanism of cyanide and oxygen adsorbed on Palladium metal. (4)The dissolution behavior of Palladium as a function of cyanide and oxygen concentration.

Invertase activity reduction is more severe compared to the HMF content increase.
Invertase activity reduction in times [1].
Using data from Fig. 3 and 4 it is possible to observe that both, the HMF content increase and the invertase activity decrease accelerates when at 450 W.
This data suggest that at lower microwave power settings the HMF is more sensitive to microwaves than the invertase activity.

But this method just could be used for qualitative analysis but is unable to give accurate data basis.
It shows that the positive ductility factor and negative ductility factor are both increased and then decreased as the thickness increases, but the reduction range compared to the ductility factor that the accumulative damage is not considered increases with the thickness.

Further accumulation of the dose caused a reduction in resistivity.
For the dose of 5×1017 ions/cm-2 (highest dose), banding the defect levels is probably produce reduction in resistivity because of the carrier transport via hopping between nearby defects.

The sputtering effect due to the ion bombardment may be responsible for RMS reduction at highest ion dose [7-8]. 4.

The obtained theoretical results of the study were compared with experimental data.
It causes reduction of electrical and mechanical overloads and increase of wind power plant reliability.
The curve of the power change in Fig. 2 shows that the stator rotation in the moment of presence in the Autonomous system excess capacity, contributes to its reduction almost to the original level.
If it is necessary to reduce the speed of the drive, the stator is rotated against the direction of its magnetic field and the rotor rotation, which causes reduction of the rotor rotation speed.

The reduction of (Zn++) zinc ions on metal is possible at the potential shift regarding an equilibrium value to the negative area.
The essence of the activation process at vibration mechanical-chemical processing (VMCP) consists in the application catalytic properties to a metal surface with respect to the reaction of zinc ions reduction.
The vibration mechanical-chemical zinc coating (VMCZC) takes place at a high activation and concentration of ingredients in a boundary layer, an electrode potential with respect to equilibrium moves to values at which the reaction of zinc ions reduction becomes possible.
In spite of the absence of some data on kinetics and mechanism of the process because of the complexity of their obtaining it is possible to consider the fact of zinc coating formation on steel parts to be determined.
