As a result, asphalt concrete surface is extensively used in surface construction thanks to its good slip resistance, flatness, comfort, noise reduction and easy maintenance.
In practical flame retardancy technologies, single flame retardant is seldom used, instead, several flame retardants or flame retardancy synergists are used concurrently, so as to achieve the result of synergy, reduction of flame retardant consumption and cost cut.
It can be seen from the data in Table 1, LOI of AC-1 is 26.3, and that of AC-4 is 26, which cannot be expected in one-component flame retardancy system.
The data above likewise indicate the importance of ATH in the composite system.
Comparing the data in this group with TC-4; it can be revealed that, addition of APP does not contribute much to oxygen index increment.

The tongue spectral data of healthy people and hepatitis patients were collected.
Hence, pretreatment described below was necessary before analyzing data.
Figure 3 shows the averaged light-source spectral data.
In the present study, most of the 512 data points between 853.59 and 1737.26nm has weak signals, lacking of definite relationships with the compositions or properties of concern, and can be considered as redundant data.
PCA was applied to the normalized reflectivity data sets collected for 44 individuals.

Daskovsky [4] and Wadlin [5] both modelled the lift reduction of a steady foil in the proximity of the free surface with potential flow theory.
The lift reduction is sensitive to the submersion depth, chord length and the span of the foil.
Data was recorded for four different oscillating bodies: two horizontally symmetric non-thrusting profiles and two horizontally asymmetric thrust producing profiles were tested.
Force data was recorded for a minimum of 50 cycles per sample at a sample rate of 10 kHz.
All data was filtered with a digital least squares low pass filter with a pass band edge of 15 Hz to remove noise and high frequency vibrations from the measurements.

It goes to management of the product life cycle (PLM) strictly, according to [12], by people, data, processes, management systems and technologies.
This tool has join data and the goal is to cooperate with customer in a preproduction stage and to observe next items.
Data, people and technologies are resources.
Also, the reduction of a waste in the organisation does not mean an extension of the product life cycle yet.
A social responsibility also pushes the reduction of vanity.

Although there was no data for the flank wear width at the cutting speed of 100 m/min from 20 minutes to 30 minutes, the wear width in the polished insert tended to be smaller than the wear width in the unpolished insert.
Cutting time dependence on the flank wear width at cutting speed of (a) 50, (b) 100, and (c) 120 m/min using diamond and SiC abrasives in AC electric field Taylor Tool Life Analysis To elucidate the mechanism of the flank wear reduction by polishing treatment using diamond or SiC abrasives, the Taylor tool life equation was used.
Actually, n can be determined using experimental data obtained from cutting experiments.
In addition, Fig.8 shows that the tool life increased for polished tools because the plots of data using both diamond and SiC abrasives shifted to the upper right of the graph.

In the cyclic voltammogram acquired in 0.1 M acetonitrile solution of sodium perchlorate (depicted by Fig. 1d), oxidation peak potential was recognised at 0.0 V and the reduction peak potential could be scarcely indentified at –0.35 V which means noticeable reversibility of the particles even in the loosely interacting aggregates.
Then firm barrier behaviour of the C1 remained stable up to 4128 h learned from EIS data showing minor deteriorated capacitive character.
The nearly intact boundary, morphology of the grains is seen in Fig. 4b, which is in agreement with the literature data, i.e., low corrosion intensity or even partial passivation of the sacrificial pigments [3].
XPS investigation of the immersion tested coating/steel interface Quantified interfacial iron oxides and paint residues based on XPS data are presented in Table 5 whereas XPS spectra of particular regions are depicted in Fig. 2.
This was caused by the enhanced electron transfer reactions between the primer and steel substrate and the catalytic effect of the nanotubes towards oxygen reduction [10] which seemingly was not suppressed completely by the semi-conducting PPy film.

It is divided into 10 subareas based on fluvial landforms and DEM data in the watershed, Hucheng River Zone, Yunliang River Zone, Northern Qinhuai River Zone, Xiangshui River Zone, Zhangcun Zone, Qinhuai River trunk Zone, Qinhuaixin River Zone, Waigang River Zone, Niushou Mount Zone and Yuntai Mount Zones, which cover an area of 497.08 km2 in all.
Data Used and Method 14 represetative scenes of TM images in 1979 and 2006 ,which covers the area studied, are employed in this paper to monitoring the change of the surface of watershed with a view to availablity of the remote sensing data, 7 scenes in 1979 and rest in 2006 among those.
Reduction of the length may be result of the disappearing of low-grade rivers, and increase of the water surface area may be associated with the construction of the hydraulic engineering, such as broadening the main channel of the rivers.
Illustrated in the Table 2, SR is below 1 in the Qinhuai River watershed, indicating that reduction of the length of the Qinhuai River is before that of area.
