The long term dynamic relation between economic growth and environment pollution is analyzed by using co-integration analysis and granger causality test, generalized impulse response function and variance decomposition method in Jiangsu Province based on the VAR model, and the related data of Environment pollution and GDP indices are from 1982 to 2012.
This conclusion can provide a great reference value for promoting sustainable economic development and formulating relevant environmental policy for Jiangsu Province. the existence of Kuznets inverted U shaped curve for economic growth and environmental pollution depends on the data from different regions and different indexes measuring the levels of environmental pollution.
Shu Dong Zhou[3]use the panel data of atmospheric pollution of the industry and between output level to find that three kinds of air pollutants and the enterprise output in same direction change.
The dialectical relation is determined by the selection of regional data and index of environmental pollution.
The all data are processed by logarithm in order to maintain the stability using Eviews 6.

Based on the engineering background as which a box-girder bridge under construction in typical winter weather of Qinghai-Tibet plateau is chosen, a diffusion equation of temperature of the structure has been established, whose choices of initial and boundary conditions are discussed according to the field monitoring data and local weather information including solar radiation and air convection.
Finally, based on the determinate parameters, the temperature fields of another box-girder bridge are simulated, which agree with the measured data in the field.
Therefore, some modification of temperature model and related parameters should be done by much measured data.
(3) Our field data are obtained on Sept.28, 2011, when.
After 16:00 pm, due to the decrease of radiation intensity, there are obviously reductions of temperature in a box-girder.

Based on the Model of the Differential Mass Conservation Equation to Establish According to differential mass conservation equation, when describing the extraction process can reflect the extraction mechanism the requiring thermodynamic parameter is less and equilibrium and thermodynamic data of the supercritical is also very imperfect.
Differential mass conservation equation model based on the assumption: (1) The porosity of the bed does not change the reduction of the solute with the solid phase; (2) the same temperature and the same pressure inside the extractor; (3) fluid flow rate in the extractor is uniform.
Using three BP network structure, As extract the oil amount for network output parameters, taking the normalization pretreatment of the raw data, specific methods are as follows: (9) 4.
The average relative error of the absolute value of the training and simulation .Figure1,2 comparison of simulation results with experimental data.
Conclusion Three-layer BP neural network structure used in this paper,for the supercritical fluid extraction process, after using the experimental data train and learn,and can make a good simulation of the extraction rate curve and obtain model is more accurate than other methods.The normalization of BP neural network not only solves the differences in original data on the order of magnitude also in network training to avoid the zero.

The advantages of optical inter-satellites links are :(1) smaller size and weight of the terminal, (2) less power consumption, (3) high security and resistance to interference, (4) high data rate, (5) denser satellite orbit population and etc.
This leads to a significant reduction in the mass and volume to be boosted into orbit and, particularly with the high data rate capacity/payloads, minimizes the risk of interference with other communications systems.
Optical system in laser inter-satellites communication Block diagram of an optical system in laser inter-satellites communication At the transmitter, the data stream modulates a laser source using Pulse Position Modulation.
At the receiver, this process is reversed and the optical signal is converted into a data stream.
Optical telescope An optical telescope is a telescope which is used to gather and focus light mainly from the visible part of the electromagnetic spectrum, for directly viewing a magnified image, making a photograph, or collecting data through electronic image sensors.

The scatter of test data under interior standard preparation is lower than the data scatter of outdoor plug samples.
Similarly, according to tension data in group 5, for C and m of effective regression, we obtain that, average s0 tends to 2.2 when m→ ∞. 42 and 2.2 is the average value of s0 when taking V=0 in Eq.10.
Because of the less data, and not the same as the sample number of each group, the conclusions also need to be studied in a larger scope.
Based on his analysis of the existing test data, Bažant proposed [14] m = 12 for the small size and m = 24 for large size [4]
Some scholars also presented data in this regard, such as J.E.

Both approaches to this issue, although different, emphasize that the reliability of measurement data is the basis for making intelligent decisions (Fig. 1).
And the facts are true when the data from the process will be collected in a reliable way.
On the contrary, the VDA manuals use previously collected data and expand on them.

The data for land (A5, E6) came from the National Agricultural Production Cost and Revenue Information Summary 2007.
The data of income tax from households (F8) was from China Tax Yearbook 2003.
Other data were balanced items in the SAM.
The data for grain-based fuel ethanol can only be obtained from 2004 even though fuel ethanol production began in 2002, and cassava-based fuel ethanol can be acquired from 2007.
Therefore, this study entered the data of grain-based fuel ethanol in 2004 and cassava-based fuel ethanol in 2007 into the SAM.

There is a high demand for input data on both material and construction side and also on modelling side.
Since these calculations are built on one another, the result can be very sensitive to the initial data.
The material quantities are calculated automatically using the geometrical and construction data of the model.
