However few studies investigated the fatigue behavior of CFRP under ultra high cyclic fatigue loading at high humidity condition, while same data was shown by researchers [5].
Result and Discussion Stiffness reduction of CFRP spring under ultra high cyclic fatigue Fig. 3 shows the reduction rate of frequency as a function of number of loading cycles in the CFRP spring.
Stiffness reduction of CFRTP spring without loading To prevent the stiffness reduction accompanying with such damages which might be induced by the hydrolysis in epoxy shown in Fig. 5(a) under high humidity condition, PET film was utilized as the material of matrix for the CFRTP spring plate.
Prevention of stiffness reduction of plate spring Fig. 7 shows the reduction rate of frequency as a function of number of loading cycles in CFRTP spring.

Design of the reusable data reduction tool Data set is a collection of data, is the object of data mining.
Data reduction tools can be called by data mining system can also be called by other cloud applications platform to access heterogeneous data.
The design of reusable data reduction tool.
The development and implements of data reduction tool on cloud computing platform.
Then test data set is to verify the effectiveness and efficiency of data reduction tool.

However, the calculation workload is too large to process data for large area.
Discrete liner transformation of potential field data [J].
Geophysics, 1989, 54(4): 497-507. ] advanced this method, but data of large area is always difficult to be solved.
The data were gridded and then upward continued 25 meters.
The resulting data and error estimates were inverted with standard inversion parameters.

To optimize the reduction technology of SSI and its removal ability for nitrate from wastewater, the influence of reduction time of SSI on nitrate removal percentage was investigated.
Because the specific surface area was impact smartly by the reduction time of SSI, it was suggested that nitrate removal ability of SSI should declined with the increasing of reduction time once the reduction time longer than the optimized reduction time.
But the higher specific area was also impacted by deoxidizer, reduction temperature and reduction time, etc.
lnr=ln(-dC/dt)=lnkobs+nlnC (5) Fig.2 The relationship between lnr and lnC According to the kinetic experiment datum shown in Fig. 1, reaction rate equations of nitrate removal by SSI reduced in different reduction time could be calculated and illustrated in Table 1.
SSI reduction could not be optimized merely on the basement of its removal ability for nitrate, other factors should be taken into account, such as reduction atmosphere, temperature, reduction time, etc.

Changchun, 130051, China 3Aviation University of Air Force, Changchun, 130022, China aliuxiaolun_jldx@163.com, b450268973@qq.com Keywords: bush roller chains, meshing impact, split roller, noise reduction Abstract.
By analysis of testing data, noise level of duplex sleeve chains with split rollers compared with that of the other duplex bush roller chains was reduced by the average 3 ~ 8dB, and low 10 ~ 13dB than that of 16A simplex sleeve roller chains.
The chains made chain drive significantly improve in the working environment, with steady transmission, strong bearing, low noise, and a significant noise reduction was achieved.
It had been concluded that contact process of sprocket tooth and non-metallic elastic material roller was noise reduction process [7,8].
Reduction of Noise and Vibration in Roller Chain Drives.

The input data for the pilot model were; 12 teeth with module of 5, face width 50 mm, pitch diameter of 60 mm and outside diameter of 70 mm.
The stress obtained was 127.7 MPa which is about 18.7 % reduction in Von Mises stress.
A maximum of 25% reduction in maximum Von Mises stress was obtained in this analysis.
The stress obtained for this case was 108.2 MPa which yielded a 31.1 % reduction compared to the pilot case.

Through the Ethernet switch conveniently and other systems for the connection and data information sharing, for the large-scale system can also set the data server and gateway server and other systems for the connection.
The method further interpretation Various types of buildings using electronic remote intelligent measuring instrument of energy consumption data ( such as electricity, water, temperature and humidity ), will realize all kinds of energy consumption data real-time acquisition and uploads to the center server.
Data transmission cable ( RJ45 LAN network port ) / wireless ( GPRS/CDMA ) for data remote transmission.
The data packet will be transmitted to the " energy saving supervision platform " in the database, a large amount of historical data is permanently stored, to facilitate future calls, analysis and reference as shown in Fig.2.
Fig.2 System hierarchical structure Internet consumption monitoring Combination of campus GIS geographic information, to the environment as the background, the building energy consumption data as the analysis object, can be intuitive for energy consumption data were analyzed, at the same time application, mobile phone, PDA and many other data terminal to implement energy detection.

The rate of reduction scales with the reaction time for both RT and 50 ℃ as evidenced from electrical conductivity data.
Therefore, the metals such as Fe, Al and Zn with dilute hydrochloric acid have been used for the reduction of GO because of their high reduction potential values.
Tin powders (100 mesh, 99.5%, Alfa Aesar, USA) were used as reducing agent for GO reduction.
However, this peak becomes broader with increasing the duration GO reduction at 50 °C.
FT-IR and XPS analysis confirms the successful reduction of GO using Tin powder.
