The data have been demarcated by apparatus, and the known instrument errors of the raw image data from the digital number (DN) are revised.
However, a series of further data processing are needed to perform.
These data have near-simultaneous coverage of the same extent in Grove Mountains.
The data difference is less than 1.5%, which indicates that the results have high reliability.
The Landsat data are used to track the interannual variation of the blue-ice extent.

To start, the capacitor cost, available capacitor, number of buses, load data, bus data, line data and other variables will be defined first as shown in Fig. 2.
In addition, each particle includes two data which are the capacitor size and bus number, and will be exported to the OpenDSS engine for power flow solution.
The loads data, Bus data, Line data and all information about this case study can be found in [10].
Fig. 3 (b) indicates the losses for each bus which there is losses reduction after the optimum capacitor installation.
It shows the nature of cost reduction during the NFE and number of iterations.

Another event is the so-called voltage reductions.
One cycle of acquired data is used to compute the RMS voltage.
The filter was employed to extract data for event characterization while the S-Transform was needed for perturbation detection.
The fuzzy system was employed to analyze the data for power quality characterization.
Numerous real-life applications use digital data today.

When the transmission was in the highest position, the automobile's power performance and fuel economy was depends on the main reduction ratio.
As the development of engine power, reduce the vehicle quality and road conditions improve, main reduction ratio has little development trend.
The Basic Data of Drive Axle Design Design of the drive axle of the light bus: maximum engine torque was 162N.m; transmission gear transmission ratio of drive axle load was 4.452; total load was 22900N; the wheel radius was 800mm; track was 1900mm. 1- the main speed reducer 2- sleeve 3- differential 4, 7-half shaft 5- adjusting nut 6- adjusting shim 8- axle housing Figure 1.
Gear type main driver can be divided into single reducer, reducer, double speed reducer, single-stage, two-stage, penetrating through single or double reduction of wheel reducer.
The main reduction must ensure the main, driven gear meshing condition was good, to make them work well.

The surface area of the sample was measured by means of a Beishide 3H-2000 instrument, and was determined by applying the BET (Brunauer-Emmett-Teller) model to nitrogen adsorption data obtained in the relative pressure range from 0.04 to 0.32.
The components of the gas after reduction were monitored by a thermal conductor detector (TCD).
Reduction-Oxidation and Acidic Properties of Catalyst.
The TPR experiment was carried out to observe the reduction-oxidation properties of the catalyst.
As shown in Fig. 3, there was a single major reduction peak at about 643 °C in the TPR profile.

Further process-oriented constant amplitude tests were performed at selected stress amplitudes in LCF and HCF regimes, in which Ecorr and total strain εt responses were simultaneously recorded with a high data acquisition rate using a self-programmed software based on LabView from National Instruments.
Similar results were obtained for DieMag422 regarding the lifetime reduction in LCF regime.
The reduction of the fatigue lifetime in LCF regime can be attributed to an accelerated crack formation due to selective corrosive attack in areas with strain localizations, as a result of localized slipping [6].
Evaluation of Ecorr,a for f = 10 Hz shows a linear increase after an initial reduction, which corresponds to the initial cyclic hardening given by εa,p.
Equivalent to the LCF tests with AE42, initial reduction of Ecorr,m at f = 10 Hz (Fig. 6a) and absent reduction at f = 0.1 Hz (Fig. 6c) can be observed.

Based on the land use data,Costanza ecosystem service value formula and correction parameter suitable for Chinasituations, the basin ecosystem service value is calculated to analyze the changes in leadingecosystem function ofGuanting ReservoirBasin in different periods.
In combination with the social and economic statistical data, the driving factors are discussed for changes in the leading function, and the approaches are put forward to enhance the upstream ecosystem function, so as to guarantee the sustainable economic and social development in the Basin.
Research methodologies The 1985 and 2010 spatial data on Zhangjiakou City ecosystem are obtained fromthe authoritative literature;the statistical data on the upstream and downstream social and economic situations are collectedfrom the statistical yearbook, the statistics bulletin of national economic and social development, as well asvarious plans for the environmental protection.
Supporting by the above spatial data and statistical dataon society and economy, the dynamic changes in basin ecosystem function are analyzed to discusses the approaches for enhancing the upstream capacity of ecosystem services.
This study is to conduct a tentative exploration of the temporal and spatialpattern of basin ecosystem service and eco-compensation relationship on the basis of the existing data and current knowledge.With increasingly complete data and deepening the related research theory in the future, thein-depth researchescould be carried out for the effect evaluation mechanismof basin eco-compensation, so as to access more accurate and scientific research results.

Owing to missing data in impact index and response index, in the empirical research, a partial analysis, including only drivers, pressures and state changes, was implemented.
The data mainly came from: - China statistics yearbook; - China environmental statistics yearbook; - China energy statistics yearbook; - The indicator bulletin of energy consumption per GDP in each province, municipality and municipality directly under the Central Government; - Statistics yearbook in Shanghai, Jiangsu and Zhejiang; - Statistics yearbook in Yangtze River Delta The data about carbon emission did not be announced.
So in the research, all the data about carbon emission were calculated in the following steps.
Firstly, all data of energy consumption by coal, fossil oil and natural gas were translated into the unit of standard coal, and then multiply by the discharge coefficient of carbon dioxide, which were identified as =2.6873,=2.0438, =1.5495.
The evaluation of low-carbon city development was fulfilled for cities in Yangtze River Delta in two steps, including DPSIR model and factor analysis of available data.
