The maximum value of vibration-reduction ratio is 36.7% at the ninth floor.
The vibration-reduction ratio increases with the enhancement of seismic acceleration and vibration-reduction effect is evident.
The effect of vibration-reduction is evident.
The results indicate that the dampers have a good effect on vibration-reduction

Most stacking faults yielded ~40% reduction in the carrier lifetime.
Moreover, drastic lifetime reductions were observed in regions containing surface triangular defects and bulk 3C polytype inclusions.
Available experimental data regarding electrical activity of threading screw and edge dislocations in SiC material suggests that these defects have different effects on bipolar and unipolar device performance [6, 7] and on radiative recombination properties [8].
The carrier lifetime in the region near several defects of each type was probed in order to provide reliable data.
Most SFs showed ~40% reduction in the carrier lifetime, while large lifetime reductions were found from regions containing surface triangular defects and volume 3C polytype inclusions.

The obtained results will allow the reduction in the number of real experiments in the creation of new materials with required properties.
The diffusion processes of iron and nickel were studied on modeling the couples Fe-Ni and Fe-NiO after a reduction anneal and sintering.
The distribution of nickel concentration in the diffusion zones of Fe-Ni and Fe-NiO according to the МРСА data is shown in Fig. 2.
It is possible to explain this fact by the raised deficiency of nickel structure after reduction that is checked out by data from the X-ray analysis.
On experimental data of the distribution of the elements concentration the mutual diffusion coefficients in the phases formed in the diffusion zone have been calculated.

For CO₂ reduction rate, the CO₂ emissions generated from a manufacturing process of existing ordinary cement products and blast furnace slag products were measured, and each range was set and judged based on the reduction ratio of blast furnace slag for ordinary cement.

However, some performance requirements lack previous examples, data, etc., so the objective and comprehensive standard setting was insufficient.
It is necessary to accumulate data through tests and constant monitoring of construction examples and carry out an additional study for preparation of objective and synthetic performance guidelines for efficient management of construction targets in the future.

According to data around the world, the global average geothermal gradient is about 3 ℃ / 100m.
Emission Reduction in thermal insulation structure This paper gives the thermal calculation about an actual gallery engineering.
Fig.3 Heat transfer quantity with the variations of and Fig.4 Terminal temperature with the variations of and The result data indicates following conclusions
Reduction rate of heat transfer quantity and temperature change In an example, when =0.15，δ=200(mm)，to compare the calculation of a thermal insulation structure with a non-insulation structure, the reduction rate of heat transfer quantity can be worked out.
At the same time, for the temperature change between the beginning and the terminal, its reduction rate can be worked out.

The results showed reduction in the number of bubbles (as well as in void content) at frequencies between 10Hz and 50Hz for 30 minutes of vibrations.
After counting voids all data was categorized into 4 groups, depending on the size (radius) of the bubble cross-section.
Once again this showed no significant improvement in void reduction; see Fig. 2 (right).
The results presented in this paper show reduction in the number of bubbles (50-500 µm) at frequencies between 10Hz and 50Hz for 30 minutes.
The mechanical data acquisition and development program is continuing and further work on the vibration parameters and theirs impact on the process will be reported in our next publication.

Hence, linear least square fitting is used for the data of coincidence part.
With the fitted data as standard, the second section data is taked translation and rotation transformation to fit the two section data.
The three times measurements result are fitted to one data according to the section splicing measurement, then compared the data above with the one time measurement results.
For fitting evaluation method, because this method is fitting the coincidence part of the two section data, so it can close to the curve of the overall trend maximum; Another method is curvature comparison method, the curvature is bending degree of curve each point, so the curved line is made up of the point closed to curve the overall trend, and has a better error reduction.
Fig. 5 This method is shown as follows: Firstly, two sets of data from coincidence part are extracted out, and the least squares fitting method is used to fit the two sets of data and the whole data to get curve C1, C2 and C.

From these data the microstructure of the scanned area can be reconstructed.
Taylor factor calculated from EBSD scanning data were also used as a measurement of an orientation-dependent stored energy in cold-rolled steels [4, 5].
The original raw data were collected using the TSL OIM data collector software.
Figure 2: Misorientation distribution changing trend during annealing Kernel Average Misorientation maps calculated from EBSD data was used in this study to approximately evaluate the fraction of recrystallized area.

An example using industrial waste gas pollution data of Beijing between 2001 and 2010 is shown.
It is completely determined by the data and has nothing to do with human subjectivity.
The steps are as follows: (1) Given there are data of years and indexes and construct the original data matrix
Because energy-environment system is a time-varying system, the result from the historical data forecasting mode has its limitations.
All the data comes from China statistics yearbooks.
