., aerobic/anaerobic biodegradation, cometabolism, dispersion, volatilization, oxidation, reduction, and adsorption).
Aerobic and anaerobic biodegradation are believed to be the major processes that account for both containment of the petroleum hydrocarbon plume and reduction of the contaminant concentrations.
Environmental conditions and microbial competition will ultimately determine which anaerobic biodegradation processes would dominate, but in a typical aquifer that is devoid of DO, denitrification typically occurs first, followed by iron reduction, sulfate reduction, and methanogenesis [2].
Three lines of evidence can be used to support natural attenuation of chlorinated aliphatic hydrocarbons, including: (1) Observed reduction in TCE concentrations along the groundwater flow path from the TCE spill location. (2) Documented loss of TCE mass at the field scale using chemical and geological analytical data, and a conservative tracer or a fate and transport modeling to document contaminant mass reduction and to calculate biological decay at the field scale. (3) Microbiological laboratory data that support the occurrence of biodegradation.

Damping Test To measure the vibration and noise reduction, damping is the capacity unit of dissipating vibration energy, that is to change the mechanical and sonic vibration energy to the heat or other easily dissipation energy and achieve the noise reduction.
The performance data in field of LNAP test trial is acceptable.After one year, the test trial has good performance which it has no damage in the surface and has good surface drainage in the rain day.

- Percent reduction of surface roughness which gives information about surface roughness reduction, using the initial surface roughness [7].
The average surface roughness reduction of the overall trials is 65 %.
Based on quadratic regression between the experimental data and the input parameters, it is possible to determinate the optimum position of the reduction of the surface roughness.

Crack initiation energies were unaffected by changing water quench temperature from 20°C to 60°C, however a significant reduction was evident on air cooling.
Typical data are shown in Fig. 3, showing both crack length and F/A0 in one graph. )20˚C water quenched and peak aged 60˚C water quenched and peak aged Air cooled and peak aged Fig. 3 Kahn tear test results: nominal stress (F/A0) versus crack tip opening displacement and crack length versus crack tip opening displacement for different quench rates. 0 20 40 60 80 100 120 140 160 180 012345 Crack Tip Opening Displacement (COD) in mm F/A0 in MPa 0 5 10 15 20 25 crack length in mm The initial nominal stresses of the 20°C water quenched and the 60°C water quenched materials are very similar.
With ongoing crack growth into the slant fracture regions of both water quenched conditions, an increasing propensity for ductile shear decohesion was noted, with a marked reduction in the proportion of coarse voiding.
Such a combination of boundary particle decoration and PFZ formation has been widely discussed in relation to generation of boundary ductile failure (e.g. see [11]), consistent with the present reductions in toughness with reduced quench rates.
• The crack propagation energy is particularly reduced as a result of the reduction in quench rate, indicating an increased sensitivity of plane stress failure to changes in grain boundary character.

Thirdly, the process of urbanization leads to the reduction of the land and causes the increase of CO2 emission.
