Many data show that only accurate grasp of nitrobenzene features and changes affecting their respective environmental factors, in order to make a scientific assessment of nitrobenzene in the environment, transport and transformation processes and destination.
Nitrobenzene migration and transformation mechanism in aquifer Nitrobenzene into the aqueous layer may be mainly through the following procedure: (1) The aqueous layer was adsorbed media particles ; (2) to the surface volatilization ; (3) biodegradable ; (4) non-biodegradable ( hydrolysis, photolysis, oxidation reduction reaction, etc. ) ; (5) to be absorbed into the food chain enrichment plant or degradation.
To determine the total rate constants of nitrobenzene natural attenuation The process of transport and transformation of pollutants in aquifer is also polluted matter natural attenuation, the process includes the physical process of solute convection dispersion and an aqueous medium on adsorption, pollutant biodegradation, oxidation and reduction process.

However, there is a lack in the experimental and analyzed data.
Finally, the concrete cover spalled in the compressive region of the column base with substantial reduction in the load-carrying capacity, while the concrete in the flange slightly damaged or even not damage at all.
Fig. 5 shows the reduction in stiffness with respect to lateral displacement for CT-3.

Respectively circumference force, axial force and shear force are loaded on the final reduction gear C,fourth gear D or fifth gear E.Solving it can get equivalent stress cloud figures as shown in figure 5.
(1) In the formula(1), H-Durable operating time(H); L-Standard necessary durable distance(km); Rm-Tire effective radius(m); im-Gear ratio in each condition; id-Final reduction gear ratio; Ne- Engine speed(r/min); -Speed in each condition(r/min); -Number of teeth in each condition.
Since tests of material fatigue data are obtained from smooth specimens, that fatigue strength parameters of smooth specimens and parts are very different.

Although there are a large number of papers which reported on foamed concrete , there is no data available on the use of WPSA and FRCA combined at different ratios with respect to compressive strength performance of lightweight foamed concrete.
Meanwhile, it can be observed that further increasing proportion of WPSA up to 30% ratio contributes the reduction in strength by the values of 43%, 19%, 22%, 20%, 12% and 15% at 3, 7, 28, 60, 90, and 180 days of curing time respectively as compared with those of the mixture containing 20% WPSA replacement.
The reduction in strength might be attributed to a higher content of WPSA that resulted in the retardation of strength due to the low value of pozzolanic reactivity of WPSA.

Weight reduction has been realized as a key priority and lightweight materials such as aluminum and magnesium are suggested to replace the traditional mild steel.
Furthermore, the quality of the formation could be improved [2]. 5xxx and 6xxx series aluminum sheet alloys are widely studied and already used in AIV(aluminum intensive vehicles) body-in-white manufacturing and show their excellent corrosion resistance, weldability, and weight reduction compared to steel [3,4,5].
The SEM observations on the fractured surfaces account for the change of tensile test and show good agreement with the data given in Fig.4 (b). 250℃ 250℃ 150℃ 50℃ Fig.5 SEM images of uniaxial tensile test fractures Constitutive equation.

Cleaning of data was performed according to a confidence index higher than 0.1.
This result allows to suppose that a straininduced mechanism of martensite formation is actually operating and that the reduction of the packet size in the central region is the consequence of the activation of a higher number of martensite nuclei per unit volume compared with the subsurface zones.
The effect of tempering temperature on hardness reduction is reported in Fig. 6 showing a loss of 100 HV10 with tempering temperature varying from 620°C to 680 °C.

:  The matching time of SUSAN-SIFT algorithm is far less than the matching time of the SIFT algorithm in each group of the experiments, the reduction of the matching time is mainly caused by two reasons:  1) SUSAN-SIFT algorithm uses a faster algorithm than the SIFT algorithm for the part of the feature point detection, so that the speed of the feature point detection has been greatly improved.  2) SUSAN-SIFT algorithm is relatively simple algorithm to SIFT algorithm, the detected feature points  are generally  some of  the more obvious characteristics of the point, making the number of feature points are generally less than the number of feature points detected by the SIFT algorithm, it is because of the reduction of the number of feature points, the algorithm saves a lot of time in the parts of generating the descriptors of the feature points and matching feature points.

Then, the data of vanillin absorption of all treated cotton fabrics were evaluated by UV spectrophotometry in 200-400 nm range after 3, 7, 11, 15, 18, 22, 25 and 31 days.
UV spectra of cottons treated with 0-20% HP-β-CD and glyoxal (a) and Knittex (b); measured after 3 days As can be seen in Fig. 3, vanillin was slowly released from the treated fabric which is confirmed by the reduction of vanillin absorption over a period of 31 days.
Unfortunately, the use of high curing temperature in glyoxal crosslinking was accompanied by the reduction of tensile strength and whiteness of the treated fabrics.
