The HTP sequence data was analysed using the Mothur software, v 1.34.2 [9] where the sequences were quality checked, adapter sequences and barcodes removed, aligned using the Silva v119 alignment as template [10], clustered into operational taxonomic units (OTUs) according the their sequence similarities and identified using the Silva v119 taxonomy database.

The GPRS transmission device first simply processing of the measured data of the displacement sensor,then package its TCP/IP and sended by the GPRS network to a data processing terminal,GPRS terminal equipment accept data from the GPRS network and send to data control equipment through the serial port.
The display device have a simple processing to the data from the data control device for display to ensure data effective transmission of real-time to the management decision-makers.
Fig.3 Central control module GPRS network transmission module: GR47is a new generation of GPRS/GSM module by Sony.GR47 can achieve voice communication,SMS communication and GPRS data transmission is a full-featured wireless communication module.The system mainly use GPRS data transmission function of GR47.It is a system of communication function module,it is a bridge between single-chip and Internet exchange data-grams and responsible connection between SCM and Internet .
Post-processing and terminal operations modules:Data processing and monitoring subsystem consists of a server background data processing and data processing and monitoring software run in the server.The software includes network data transceiver module, system parameter setting module, processing module of the monitoring data and monitoring results display module TCP / IP data from the GPRS network, after the dismantling of the network data transceiver module generate a series of observation data file by the data file management module.The amount of displacement data of the observation point obtained after data analysis to display module,digital text and graphics appear on the display interface.

Data and econometrics methodology Econometrics Methodology.
Data.
The variables are the arithmetic average data.
Energy price data are not easily available for all provinces, and so the energy prices are proxied using the price of Dubai crude oil (p).
All of these data are available from China Financial Statistical Yearbook, the CSMAR database and Wind database.

In this theory, we can know the “sustainable” developmental potential of human race in one area by obtain the ED data.
It should be that our development is “endurance” when the ED data is “ecological gain” but not “ecological deficit”.
According to the ED data, there were still 12 provinces and cities of China are “ecological surplus” in 1980.
It is just like different tunes sung with equal skill with the modern composite wall which is especially designed for energy saving and noise reduction.

The unknown parameters in LuGre model are main depend on the contact feature of the interfaces, and usually can be identified from measured data.
Simulation data was acquired at two force levels for random excitations and two frequencies for sine excitations as shown in Table.1.
By the statistical analysis of this simulation data, the vibration amplitude was restrained effectively by friction force.
Through investigation, we arrive at the following conclusions: (1) Friction can be used for vibration reduction, which absorbing is good and vibration damping is rapid

The 2507 SDSS is not recommended for applications which require long exposures above 300°C because of the risk of a reduction in toughness.
The magnetometer is completely computer controlled, the measurement and the excitation are performed by a National Instruments data acquisition card (DAQ) and a PC.
The data acquisition, processing and the control of the set-up were done by a LabView VI.

The former refers to the rate of speed with two positive data, the later is one positive data and one negative rate.
In this study,relative decoupling refers to a situation when the growth rates of CO2 emissions, and industrial output increase simultaneously but the later data is slower than the growth rate of carbon emissions.
In Fig.4,it indicates that in 1998, the growth rate of Shanghai industrial CO2 emissions is negative, while the industrial sector economic growth is still increased, which lead to an absolute reduction.

The reduction of the collision rate is the key point that can affect the performance of an RFID system.
In QT algorithm and BQT algorithm, each time to send or receive data length is always the whole L bits.
However, most of bits are not to transfer valid data so that it prolong the time of communication and decrease the efficiency of transformation.

Aside from surface temperature, the air temperature, relative humidity, solar radiation, and precipitation data were also observed as weather conditions from a separate measuring station on the roof.
A GRAPHTEC data logger (GL-450AS) was employed to record the data.
The differences in temperature were 9.1 °C and 5.8 °C, and the ratios of amplitude were 67.4% and 43.0%, whereas reduction percentages in heat transfer were 68.3% and 79.8%, respectively.

For the noisy signal which contain Gaussian white noise, 99.74% noise are reduction if the threshold value is set as the next formula: , where t is the threshold value and is Gaussian white noise standard deviation, furthermore, a suitable constant multiplied by could be the best threshold.
MSE(mean square error) function presents the difference between the real signal and the estimation data.
By testing on the noisy signals which including wavelet noise test data, we can prove the accuracy and effective of the genetic adaptive algorithm.
The test data of experiment 2 is ‘bumps’; the experiment 3 using ‘heavy sine’ signal.
