Data Collection Displacement measurement shall immediately start when all load are completely imposed, first reading is corresponding to creep at zero time.
This test will use the software which is specially developed for creep test to carry out data collection.
Data Analysis Method Relationship between creep elongation rate of the conductor and time follows exponential law, which shows linear relationship on the double logarithmic coordinate.
Carry out analysis on test data, obtain coefficient in creep equation, apply the creep equation to calculate creep quantity after operation for 10 years and 30 years, and provide the regression curve[6].
Section ratio between aluminium and steel of JL/G3A-1000/45-72/7 conductor reaches 23.25, which greatly exceeds specified scope of the specification, and the temperature reduction value shall be obtained from calculation and analysis of test data.

Soft Reduction of a Cast Ingot on the Incomplete Crystallization Stage Tatyana I.
Numerical and physical simulation on model samples can provide data for various aspects of metal forming, without resorting to time-consuming and costly full-scale tests.
It also provides a novel method for studying the process of soft reduction.
In the given geometry and pressure of 1 MPa, the reduction of the inner zone is 30% greater than the reduction of the solid part.
In the given geometry, the reduction of inner zone is 30% greater than the reduction of the solid part.

Catalyst characterizations X-ray powder diffraction (XRD) data were taken Bruker D8 diffractometer equipped with CuKα(l=0.1541 nm) radiation operating at 40 kV and 40 mA for 2θ angles ranging from 1.25° to 80° with a step interval of 0.2°.
a: ML, b: OMS, c: Cu-ML, d:Cu-OMS The N2 isotherm adsorption-desorption data for ML, OMS, Cu-ML and Cu-OMS after calcined are displayed in Fig. 2.
However, commonly used method to obtain results of adsorption-desorption data and the downstream calculations may not very accurate about this type of pore structure.
The other reason is the bounded water in the interlayers, which maybe affect the desorption data, and lead to the adsorption-desorption isothermal cannot return.
So, the N2 isotherm adsorption-desorption data still meaningful at here.

Energy saving and economic growth: Empirical Analysis Based on Panel Data Dongheng Hao1, a, Guozhu Li1,b and Dianru Wang1,c 1 School of economics and trade, Shijiazhuang university of economics, Shijiazhuang,050031,.China ahaodh@sjzue.edu.cn, bliguozhu@sjzue.edu.cn cwangdianru@126.com Keywords: Energy Saving, Economic Growth, Panel Data.
Abstract. we analyzed the relationship between energy conservation and economic using panel data. the reduction of energy consumption per unit of GDP and energy consumption per unit of industrial value-added will promote economic growth, however, lower electricity consumption per unit of GDP may inhibit economic growth.
Methods and variables When the sample time is short and the provinces situations are very different, panel data can combine time series and cross section, it can control the factors that are unobservable due to difference between provinces, there minimizing the errors of results.
Specifically, there are three main advantages for the panel data.
Because of the short time dimension and the large cross-section, the data of this study is a short panel.

Study on Preparation of Metal Sm by Metal Thermal Reduction Method Ping XUE School of electromechanical and architectural engineering, Jianghan University, Wuhan, Hubei, 430056 xueping20011982@163.com Keywords: Metal thermal reduction method; Metal Sm; Thermodynamic calculations; Direct yield Abstract: In this paper, thermodynamic calculations and reaction process for the production of metal Sm by metal thermal reduction method were analyzed.
The preparing method of metal Sm is mainly metal thermal reduction method by metal Lanthanum or Cerium [2].
According to relevant references, the data of Lanthanum and Cerium reducing reaction are as follows [2]: 2Sm2O3(s)+2La(l) →2Sm(g)+La2O3(s) ΔGT=102940-48.77T+8.314Tln (0.1/101325)2≤0 T≥2110.7K Sm2O3(s)+2Ce(l) →2Sm(g)+Ce2O3(s) ΔGT=97600-47.12T+8.314Tln (0.1/101325)2≤0 T≥2071.3.7K It can be seen from the above data that the thermodynamic conditions of the reaction can be carried out above the reaction temperature 1800℃.
Experimental results and discussion 1kg drying Sm2O3 powder is weighed and added with the reduction metal at the proportion of 1:1 (the reduction metals are the chips of the La-Ce mixed metal ingot after turning).

Compared with the traditional management information system (MIS), GIS has spatial data and attribute data.
MIS only has attribute data.
The data is graphic, stored as files.
GIS is the data source of the spatial load prediction for data collection, processing and results display.
It exchanges data with distribution automation system to achieve real-time data information.

Magnesium reduction Jar can be critical, consumable parts in magnesium reduction process, this paper Introduced the working environment and the common failure modes of magnesium reduction can, based on the failure can cause magnesium reduction, presents a The new structure, developed a new material, and magnesium can restore the original structure was modified, the use of new casting technology to produce a good magnesium reduction tank.
This paper analyzes the failure of Magnesium reduction Jar cause reduction, developed a new material, and magnesium reduction tank’s original structure was modified, the use of new casting technology to produce a good reduction Jar. 1 A typical structure of reduction Jar and its work environment The size of reduction Jar is320mm×(2650~2700) mm or the standard 339×(2650~2700) mm, wall thickness is 30~35mm, which lie put to gas and coal as main fuel reduction furnace, its openings exposed on one end of a length outside the furnace wall to form a multi-pot reduction furnace structure, the specific structure shown in Figure 1 [1,2].
Field test data show that: shell cracks appear on the site of intensive work exactly corresponds to σ phase precipitation temperature range parts.

The data source of an energy flow diagram is from the statistical data in the energy balance sheet for a region.
Investigation of the city’s energy flows and the major industries’ energy consumption, structure and carbon emission can provide data and decision supports to draft CO2 controlling measures for the dominant industries.
However, concerns and practices on CO2 control just starts, research on air pollutants reduction which collaborates with CO2 emission reduction is very necessary.
This model can be used to evaluate the regional air pollutants, CO2 emission and economic investment, and support data collection and decision makings.
In this paper, only current data and conditions were analyzed.
