Data was recorded over the frequency range 10 Hz to 1000 kHz.
From Table 1, it can be noticed that the increase amount of GeO2 content causes the reduction of density and the increase of Tg.

Table 2 summarises data on temperatures of solution annealing, linear austenitic grain size, the Rp0.2 values at both 20 and 300°C and the creep strengths for 104 and 10 5 hours at temperatures of creep testing.
Small additions of niobium to the AISI 316LN steel resulted in a significant reduction of steady creep rate and shortening of the tertiary creep stage.

The samples were solution treated at temperature 470 for 2 hours in an resistance furnace, which was determined on the basis of literature data and calorimetric investigation [3,4], and cooled with water, Then compression deforming was exerted on samples in universal testing machine, and the compression ratios were calculated by height reduction from 10%, 20%, 30% to 40% respectively.

Definition of symbols : Wind power electricity cost per Kilowatt-hour of the year : The total construction cost : Annual maintenance cost : Annual fixed expenses : Annual interest cost : Annual tax cost : Design life of the wind farm : The Quantity of grid electricity of a year : The amount of subsidies per Kilowatt-hour : The proportion of loans in the specific project : The sum of already paid principal : Loan period : loan interest rate : The value-added tax The model can be represented by the equation: (1) Which, l , , was given by the specific project data.
The corporate income tax of wind power enterprise is calculated by 0.04 yuan/KWh, which follows the principle of “reduction in the first three years and halves in the next three years”.

Adaptive Immune Vaccine Algorithm Adaptive immune vaccine algorithm [9] can effectively overcome disadvantages of the basic genetic algorithm, like premature convergence, poor ability of local search, and diversity reduction.
Characteristic data are shown in Table 1.

Under the arid climate, both dry and little wet saline soils have melt sinking features, which will be melt sinking deformation and got strength reduction under the soils’ weight pressure or supplementary pressure of the earth surface [4].

However, further reduction of these large epitaxial defects is required in order for SiC devices to handle higher power densities.
With respect to the data in Table 1, 27 sites where TSDs existed with the morphological feature were checked, and it was confirmed that extended defects appeared in 21 sites.

The data also show that all the materials exhibit a consecutive reduction in the magnitude of SR due to their relatively slower swelling rate when compared with their shrinking rate.

The development of new grades of hard-to-treat steels and alloys [2-3], as well as the need to improve the productivity of metalworking operations, require the improvement of existing tool materials in the direction of further improving their properties, including high-temperature properties, primarily due to the reduction of the grain size to the nano level [4] and the replacement of cobalt binder for more heat-resistant ceramic [5].

The transfer speed needs to be greatly reduced to cut with a slenderness ratio of 7, as shown in the figure, and the determination of the machinable area considering the slenderness ratio that can be used to define the cutting conditions in further research Fig. 9 Determination of the machinable area under various cutting conditions involving a 5-axis CAM automatic module of an impeller resulted as the useful data of this study [3].
Conclusions (1) A large slenderness ratio of the tool increases the vibration of the tool and the remaining cutting amount, but the surface roughness of the machined surface tends to improve due to the burnishing phenomenon and a reduction of the actual cutting amount
