Reduction in area is affected by second phases and inclusions.
Tensile strength-reduction in area balance Figure 6(a) and (b) shows the variation of percentage elongation and reduction in area as a function of the volume fraction of cementite.
The test data of conventional ferrite-pearlite steel [12], tempered martensitic steel [12] and bainite steel [13] are also plotted in Fig. 7 for the purpose of comparison.
Reduction in area is a measure of formability as well as uniform elongation.

For most of the problems about anti-sliding stability with unknown sliding surfaces, strength reduction finite element method can be adopted [6-8].
Different reduction coefficients of material strength are selected to analyze dynamic anti-sliding stability.
Different reduction factors are chosen to calculate from the initial state.
The mutated moment of displacement is considered as destructional moment during the reduction process of strength, and reciprocal of the reduction factor at this exact moment is the safety coefficient [16].Diagram of plastic zone of the sliding moment can be gotten at the same time of calculating the safety coefficient.
Data of water level in different working conditions is shown in Table 1.

What the grey theory established is to generate the data model but not the original data model, so the data in the grey prediction is the inverse processing results of the prediction got by the model GM(1, 1) which is used to generate data.
Setting x(0)(1), x(0)(2),..., x(0)(M) are the original data of certain index need to predict.
(3) Where, and B is a constructed data matrix.
For , which is the prediction of the linear accumulation generation series, we can calculate the reducing value of the original data
The choice of the original data.

Considering the geotechnical conditions of the analyzed site as input data, in this paper various dimensions and geometric configuration of the columns are evaluated, with specific purpose to determine an optimal solution that meets the technical performances of the project.
One can observe a reduction and a stabilizing trend of the settlements over time, with the introduction of the columns.
This version led to the reduction of the settlement from 10 cm, to 5.7 cm.
As expected, the 1 m diameter and 1.2 m interspacing columns had the best effect, which resulted in a reduction of the settlement from 10 cm to 2.7 cm.
However, both modifying the interspacing by decreasing it, and increasing the diameter of the columns will have, at one point, a negligible effect on settlement reduction.

The storage and management of solar energy data are of good performance.
In the solar energy engineering, it is often to store the acquisition data, query and update the solar energy data.
Fig.3 Data input interface developed by VC++ MFC These measured data can be input into SQL Server database with the help of the user interface developed by VC++ MFC, as Fig.3 shows.

The data of energy saving is as shown in table 3.

Generally, the technologies of noise control and vibration reduction in railway including isolation, absorption, sound insulation, and sound-absorbing [3].
With a condition of 60km/h speed, analysis results of the data from 2000 Hz to 22000 Hz dispalyed that the equivalent sound level would be reduced for up to 5.4 dBA, and the maximum sound level is diminished about 2.7 to 7.4 dBA.
The function of noise reduction by dampers is due mainly to the significant inhibition of the noise from wheel rail, whose frequency is rather high.
The vibration data of track and platform under the 2000 Hz~22000 Hz band demonstrated a decreasing trend, reflected as more than 2.2~9.6dB reduction in vibration acceleration level, and more than 0.7~8.6dB of the maxmium vibration acceleration level of tracks diminished.
The total noise of the train with a low speed is comprised by a large number of wheel noise contribution, hence, the reduction function by masked damper would be limited to some extent.

After 30min irradiation, Cr(VI) reduction efficiency reached 100%.
The pH value has great effect on the photochemical reduction efficiency of Cr(VI).
So high acidity is in favor of reduction of Cr(VI) by ferrous ions.
The kinetics data of Cr(VI) photoreduction is shown in Table 1.
The cycle further speeds up the reaction of Cr(VI) reduction.

In this paper, meso-mechanical analysis is used and a two-parameter model is developed to describe the stiffness reduction.
Then with the help of the damage evolution, the stiffness reduction of laminates can be predicted.
Table 1 shows the strength data of a [0]8 laminate with 56% fibre.
Under high stress level, fibre breakage is the dominant factor to laminate, which lead to the stiffness reduction to be linear reduction.
Stiffness reduction mechanisms in composite laminates.

The test cases reduction approach provides suitable test cases inputs for fault localization
They proposed vector-based reduction techniques and found that statement-based reduction strategy provides much greater reduction of the test-suite than vector-based reduction, but vector-based reduction is more effective on fault localization.
(3) The third method analyzes both data dependence and control dependence.
However, it only analyzes the branch prediction and control flow graph, so the faults relevant to data flow cannot be analyzed.
Unfortunately, there has not been any study that investigates the test cases reduction based on the execution path.

Energy saving and emission reduction is a necessary way for China to develop low carbon economy.
Thus, there is still a great of potential for energy saving and emission reduction.
Data resource This paper focus on the interconnection between energy intensity and structure evolution and scientific technology progress from 1995 to 2010, we can get the GDP, total energy consumption and each type of energy use in industry from China statistical yearbook 2011 [1], as for the carbon dioxide emission, we take the energy coefficient from IPCC 2006 as reference, which means the carbon dioxide emission coefficient of coal, oil and natural gas are 2.74, 2.14 and 1.63 t/tce, respectively.
The aggregative scientific technology progress index comes from China scientific technology statistical yearbook 2003-2011 [5], because the lack of statistical data from 1995 to 2001, so we only get the data from 2002 to 2010.
Also based on the four models, we make a potential analysis about the two factors on energy saving and emission reduction in the future.
