In sum, the power consumption of electric buses and sedans are 126 kWh and 17 kWh per 100km, which are close to the news report and data statistics in China right now [12, 13].
The data of fossil energy consumption and CO2 emission are shown in Table 1.
According to data from China Statistical Yearbook 2011 and China Energy Statistical Yearbook 2011, 800 million toe of coal are consumed in power generation and heating in 2010, correspondingly 8.998 million tons of SO2 and 1.99 million tons of soot are emitted in electricity generation industry.
The data of pollutant emissions for PVBs are unavailable since the National Bureau of Statistics China did not release any vehicle emission data.
The emission data of PVBs can be obtained through National Standards from Standardization Administration of China in this paper.

The reduction process has been reported in our previous works [8,9].
To maintain higher reduction rate, the reduction temperature was controlled under higher temperature.
As mentioned preciously, the carbon monoxide possesses lower reduction rate compared with hydrogen, the reduction temperature of SSI reduced by charcoal was much higher.
According to the kinetic experiment datum shown in Fig. 1 and Fig. 2, reaction rate equations of cadmium removal by SSI reduced by charcoal and hydrogen under T1 and T2 temperature could be calculated and illustrated in Table 1.

Data calculation and analysis Energy efficiency index I (nondimensional) is used to evaluate the relationship between energy utilization and operation condition of the treatment system, which is defined as the ratio between the pollutant removal rate R and energy parameter E: (1) I reflects the contribution of the system energy consumption to the wastewater treatment, that the bigger the I, the higher the energy utilization efficiency is.

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.

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.

Most recently, wavelet analysis stands out to be a powerful tool for signal processing including data compression, data transmission and denoising.
The data are acquired spirally at the sampling interval of 1 mm.
Fig. 7 shows a sampled data of thickness.
SMA, Gauss WMA and Haar WT are applied on that sample data to study their performance of noise reduction.
In other word, the noise account about 10% of measured data.

The data in Table 1 show that Reynolds number Re < 2300 in the main vessels, where all flow is laminar, with only weak turbulence possible at small structures in the wall or at vascular lesions.
As can be seen from the data in the table, when the number of grids reaches 479248, the error between the numerical simulation results and the theoretical value is approximately 3.3%.

Preface: Data is the source of knowledge.
While data mining refers to automatically extracted from the data model.
Including many steps: data mining from large database (or data from other sources); Select the appropriate attributes; Select the appropriate sample strategy; Eliminate data in abnormal data and make up the insufficient part; With proper dimension reduction, transform the data mining process and data model fit or match; Identify whether the resulting knowledge you have will be the result of the information or visualization, and then combined with the existing knowledge.
Statistical analysis of test data, clustering is useful on parameter design and experimental data.
Most of the pattern recognition algorithm and the method of dimension reduction, transform and set has a direct reference significance.

The development of seawater batteries has constraints on oxygen reduction reactions in the battery discharge process that runs slowly.
Based on research data, N and Fe doped carbon aerogels have better seawater battery performance than N-doped carbon aerogels without Fe.
Slow oxygen reduction reactions must be resolved by using an electrocatalyst to improve the performance of seawater batteries.
The Fe3O4 was used as an electrocatalyst of oxygen reduction reactions [12], [13].
