The role of greenbelt of the noise reduction is relate to the green belts ‘structure and composition and the width.
According to the data show that: the green belt which considered from noise reduction should not be less than 10m, the length of the noise goal should be not less than the length along the road direction.
Sound barrier noise reduction measures to be taken to solve the problem of urban traffic noise is likely to be more reasonable and feasible and acceptable to the public, and widely recognized as the main noise reduction measures by international, been very widely used.

Recently, vehicle population in China has reached 199 million according to data released by Ministry of Public Security Traffic Management Bureau.

However, further increasing of AA charge resulted in a slow reduction of kappa number.
As shown in fig.2, similar to kraft pulping, the data for same AA but different temperature and duration fall onto same curve.
Therefore, as pulp yield without apparent reduction, a relative low Na2SO3 charge would benefit the bleaching of unbleached pulp.
The results show that all data surprisingly fall into one curve, which was different from the results of kraft pulping and conventional Soda pulping.
Moreover, the data from different AA charges have same relationships between kappa number and pulp yield.

Results Fig. 2 illustrates the collected data from immersed bending fatigue testing performed using the developed test rigs.
Also, the data indicates that the tested wire specimens can withstand stress amplitudes on the level of yield strength for about 100,000 (a) (b) bending guide plate specimen rb y Fig. 1.
This data is summarized in Fig. 3a.
Conclusions The data from bending fatigue tests show that fatigue life of copper alloys depends on the composition and manufacturing parameters.
However, for evaluation of fatigue performance in seawater environment, this study shows that it is important to conduct the immersed fatigue tests in order to get reliable data.

Concrete Face Strain and Stress Observation Data Analysis.
Based on the Duncan E-B model and the deformation monitoring data, the construcion process were simulated accurately.
Generally speaking, all these results above are basically consistent with the observed data of strain gauges.
Compared with the observation data, the simulated results are close to the actual operation situation.

These algorithms for nonlinear structural characterization data demonstrated a very good effect.
In order to enhance the algorithm’s ability to make the sample data being more real-time, researchers made some improved algorithms later, such as the degree of isometric mapping, unsupervised discriminant mapping and linear local tangent space alignment (LLTSA) [7] algorithm.
