Besides, the reduction of IUV/Vis ratio of PL reveals that the ex-situ Fe doping deteriorated the crystal quality of ZnO NRs.
Linear plots are obtained when the absorbance data are plotted as ln(Co/C) of the time-dependent normalized dye concentrations (which is the ratio between the initial concentration and the concentration upon reaction) in Fig. 9 (a).

The crystalline structure of adsorbent was analyzed using XRD and gave 4 peaks characteristics of gold metal on 2ϴ = 38º, 44º, 64º, and 77º after adsorption which indicated the reduction of Au(III) ions into Au(0).
From the previous research, adsorption and reduction of Au(III) into Au(0) using cotton cellulose and concentrated sulfuric acid[4], starch[5], and tannin compounds[6‒8] had been studied.
From the data, 3 curves were made from 3 variations of treatment.

Data warehouse focuses on data modeling and data analysis of decision makers, rather than on the daily operation and transaction processing of the organization.
Nonvolatile: a data warehouse always stores data separated physically; the data derives from the application data of the operating environment.
Usually, it only needs two kinds of data access, i.e. the initial loading of data and data access.
Decision-making data is multidimensional data, which is the main content of decision-making.
Drill - up climbs up through the hierarchy of the dimension concept or gathers in a data cube by dimension reduction.

The data’s treatment and result of the prefabricated fatigue crack experiment According to the records from the high-frequency fatigue tester’s data acpuisition system,fatigue crack’s extension condition in each group are given in tab1-3 to tab 1-4.
Firstly, testing materials’ gerneral mechanical properties in usual temperature condition ,finally, use high -frequency fatigue tester to prefabridate fatigue crack to all specimens in usual temperature condition ,and use the data acpuisition syste to record the data in the process of fatigue crack’s extension test to get the crack’s extended length and cycle number’s test number, which provide a verification to fatigue simulation calculation.

However, the real horse riding in real life will be constrained by time, space, horses, equipments, and many other conditions, in response to these shortcomings, the design of the rehabilitation horse can alleviate cervical disease, fatigue, hip and abdominal fat reduction, body shaping and so on.
PCF 8591 8-bit A/D and D/A converter -- Product specification, OL. http://www.nxp.com/documents/data_sheet/PCF8591.pdf ]; it is a monolithic, single supply, low power, 8-bit CMOS data acquisition device with 4 analog inputs, one analog output and a serial I2C bus interface, moreover in the PCF8591, input and output of the address, control and data signals are transmits with a serial manner through the two-lane and two-way I2C bus, the maximum conversion rate is decided by the I2C bus maximum rate.
The logical of main program is: after the controller electrified, first, reading data which is stored in E2PROM to boot reset and initialize parameters, and then enter the main loop.

Also, a data acquisition program was edited in Labview.
It was connected with the upper computer through an USB data cable.
Also the data can be lead to Matlab to draw images.

Statistic data analysis shows that neither γ variant orientations nor interface misorientations are randomly distributed within a given grain.
Thus, the data reported in Table 1.b only correspond to measurements within one grain.
Data also indicate that there is a considerable inequality between frequencies of variants within a group.
Table 3 collects statistical data relative to the sand-quenched sample (fine lamellar structure).
Actually, such a selection has already been proposed by others authors [v,x], who attributed it mostly to a reduction of high energetic γ|γ interfaces at the benefit of less energetic ones during last time of coarsening.

Advantages: less financial investment, large and comprehensive functions, highly centralized and consistent access, procedure and data.
Each system is completely independent mutually; the real-time data exchange is realized based on unified data standard.
Secondly, the formulation for standardized processes, data specification and template shall be speeded up so as to realize a unified data standard for business and data, which is an important basis of the success of unified platform nationwide.
No matter which construction model of electronic platform is purchased by the government, they all involve the cross-sector data sharing, namely, how does government purchasing platforms obtain the useful data from other functional departments and provide the useful data for them.
Firstly the specification for unified basis data including purchaser data, supplier data, specialist date, commodity data and procurement performance data shall be unified; Secondly, the technology applications shall be unified, such as CA certification encryption technology, finally, such centralized data management centers on constructed government procurement as government procurement supervision departments and centralized procurement institutions shall unitedly manage the dynamic data in the terms of supplier registration, commodity information maintenance, specialist management and data storage, etc.

Design and Test of Silent Chain Including Silicon Fluorine Rubber Link Plate Xiaolun Liu 1,a, Song Ding 1,b, Wei Sun 1,c, Wencheng Wang1,d, Jiajun Liu1,e, Bin Jiang2,f 1 College of Mechanical Science and Engineering, Jilin University, Changchun, 130022, China 2 Aviation University of Air Force, Changchun, 130022, China aliuxiaolun_jldx@163.com, bdingsong10@mails.jlu.edu.cn, c450268973@qq.com, d576869677@qq.com, e120622570@qq.com, f136593725@qq.com Keywords: Chain Drive, Silent Chain, Silicon Fluorine Rubber, Noise Reduction.
According to the test data, we find the average noise level of silent chain including silicon fluorine rubber plate is 1dB lower than inside and outside composite meshing silent chain and 3dB lower than the outer meshing silent chain, and this verifies the low noise property of silent chain including silicon fluorine rubber plate.
