Introduction The report published in the Proceedings of the National Academy of Sciences(CICERO, 2008) pointed out that the global carbon emissions had increased by 13% in the past 10 years, in which the carbon emissions from transportation increased by 25%, and the data will increased by 30%-50% in 2050.
Average transport distance of railway transport is 595km(NBS, 2006), and every kg of saved diesel is equivalent to an emission reduction of 3.06 kg CO2.
The present is 80-95%, and is 6.62%(CEC, 2012), After substituting related data into above formula, following results were obtained, power transmission efficiency was 74.70-88.71%, when electric vehicle charge 1kWh of electricity, power plant should produce 1.13-1.34kWh of power.
Besides introducing energy-saving emission reduction technology in electric power generation, the CO2 emissions of coal-fired power generation side caused by electric vehicle can also be reduced by improving battery charging technology and by reducing power consumption per kilometers.

However data about one of the main performance indicators of acoustic isolation of mineral wool – coerced dynamic modulus of elasticity Ep are absent.

The difference 7 [dB] (under a load of 2000 [N/m²]) and 1 [dB] (under a load of 5000 [N/m²]) shows reduction impact noise by the use of basalt wool.

According to electrochemical polarization data, some investigators reported that the synergistic effect of Sc and Zr increased the corrosion resistance of 7xxx series Al alloys [3,4], while some authors reported that the combined action did not reveal any improvement in the corrosion resistance of 7xxx series Al alloys [5].
Table 2 Electrochemical data from analyses of polarization curves.
The reduction of maximum corrosion depth indicates that the addition of Sc addition can enhance IGC resistance of medium strength Al-Zn-Mg alloy.
Discussion Wloka et al. [6] reported that the addition of Sc get the alloy less stable against corrosive attack on a macroscopic scale, which was attributed to the reduction in the protective property of oxide layer across the coarse primary Al3(Sc, Zr) particles/matrix interface.

Therefore, magnesium products has been come to the fore since the industry has a demand for lightweight construction materials regarding legal requirements for CO2 reduction.
The bars with an initial diameter of 40 mm were rolled to an end diameter of 8 mm within 14 passes without using lubricant or reheating during the process, which corresponds to an area reduction of 96 %.

The adopted transport policy for the city of Czestochowa, leads to the following specific objectives: - Increasing the efficiency of the city with the increasing levels of motorization, - Improving the quality of services offered by the municipal transport company, - Improving parking conditions, - Reducing emissions generated by transport, - Noise reduction, - Improving road safety, - Improving the economic efficiency of transport.
The data for the year 2015 are only estimates, however, given the nature of the investments and sustainable transport policy objectives, it can be assumed that the use of public transport and cycling will increase, together with the reduction in the number of accidents and pollution emissions into the atmosphere.

They expressed parallelism by creating parallel data structures and invoking the parallel operators.
Similarly, we define two documents in the same data set.
After increasing the percentage of data selection, the average accuracy was 96.8%.
Classifier was designed to make use of a development test data set to avoid overfitting of data so that while estimation of accuracy, our method shows better result.

The result and analysis of the experiment At a certain temperature（different bed thickness and initial moisture content）, we plot the drying data of rice husk and cornstalk in the same figure.
Theoretically, the increase of the bed thickness will lead to reduction of the concentration differences between air and moisture content which is a driving power in the process of drying.
Here are the analysis of data with rate of drying time and drying rate.
Due to a large number of data is deficiency, so it is difficult to analyze the regular pattern in detail for the whole drying time will increase with the adding of layer.
