Introduction The rapid reduction of the quantity of rural residents and rural settlements is the irreversible phenomenon in the course of urbanization and industrialization.
Urbanization results in the reduction of rural settlements and population.
The data of Suzhou in 2010 show that the total amount of the primary industry output as a percentage of the total GDP is less than 2%, but there are 3.57 million people who depend on agriculture to feed themselves.
It is a complex factor integration As such, we need to break it down to the following three steps:1. to research the quantity and the change of distribution method, based on the change of lifestyle of rural residents in the process of urbanization and the inevitable trend of the reduction of the number of rural residents ;2. to analyze the effects of rural residential cluster from the perspective of urban-rural integration, and then obtain the relevant factor integration which influences the way rural residential settlements form; 3. to compare and contrast factors obtained from the first and second items with development goals, including the maintenance and nurturing of the agricultural industry, the integration of spatial resources, the cultural heritage from the farming tradition, the protection of local geographical landscape and so on.

However, these methods which facilitate NOx reduction may cause the increase of particulate matter.
To optimize the PM and NOx emissions simultaneously, micro-emulsified biodiesel is adopted which combines the strength of biodiesel in PM reduction and the benefit of micro-emulsion fuel in the decrease of NOx.
The engine experimental data are acquired at the rated speed of 2900r/min by varying loads (10%, 25%, 50%, 75% and 100%).
And the low aromatics content of biodiesel is another reason for soot reduction (According to soot formation theory, the aromatics especially the polycyclic aromatic in fuel is considered as the precursors of soot formation[2]).

Currently, there is still not many data on CO2/brine system relative permeability models for various rock types [6, 7].
The hybrid system of eqn. (5) is solved by implementing Schur Complement Reduction, for detailed derivation, readers are directed to [14].

Because of the significant computational time reduction and satisfactory prediction accuracy, the SRM model is recommended for a 1 year prediction of CO2 flow in preliminary study.

Solutions to cracks on lightweight concrete hollow block wall Solutions to cracks on lightweight concrete hollow block wall mainly consist of the following aspects: (1) In the production of lightweight concrete hollow block attention must be paid to these aspects: improvement of block performance, reduction of coefficient of shrinkage; use of rigid concrete and coarse aggregate and reduction of water cement ratio during the building block process, enforcement of vibration in the production process to make blocks more dense, guarantee of maintenance period out of factory not less than 28 days; guarantee of the block to keep dry and reach the moisture content standard; use of advanced technology, reduction of shrinkage value, improvement of shear strength of the block

Percentage of DMA Concentration Reduction Results from UV-Vis analysis show similarities to the trends observed from GF-AAS results.
From UV-Vis data obtained, it shows that the ability of TiO2-ZSM5-SH to degrade DMA is better as compared to ZnO-ZSM5-SH.
The concentration of DMA decreasing as time but the optimum time for best reduction of DMA concentration is 1.5 h.
As time is prolong, the percentage of DMA concentration reduction decreased.

The CoF were obtained from the polishing platen motor current values which were captured using data logging software throughout the polishing process.
Between the two defects, surface scratch counts reduction is more prominent (about 3 folds) than micro defect.
Similar phenomenon can be seen on the reduction in surface roughness (Ra) as illustrated in Fig. 6b.
The reduction of both micro-waviness and surface roughness correlates well with the increase on the concentration of FMA added to the slurry.

As a result, increasing environmental requirements increased mainly with respect to the reduction of vehicle emissions causing greenhouse effects.
Therefore, reducing the steel mass will optimize the vehicle mass reduction.
The corresponding forming limit curves were obtained by joining the strain data in order to define the lowest limit strains.
This sharp reduction is not apparent in 130 mm blank width up to 220 mm circular specimen for DP600 steel and 140 mm blank width up to 220 mm circular specimen for DP800 steel, suggesting that either a ductile shear fracture or a ductile tensile fracture takes place without any prior plastic instability.

The data from two distinct areas were taken to compensate of their accuracies. 3.
Effects of all the microalloying elements on reduction of the rave are listed in Table 1.
Although most elements showed no remarkable effect, some reduction of the rave was obtained by addition of C, Cu, In, VN, Mn3N and LaN.
It is seen that a small rave can be obtained by a small amount of doping elements in all the cases and that an amount of Mn3N less than 0.05% is the most effective for the reduction of rave.

Test block and results are shown in Figure 1. 3 Discussion and analysis 3.1 Mechanical properties For more intuitive and accurate understanding of the mechanical properties of the material, sample tests results on each three indicators have been averaged, mechanical properties to tempering temperature curves have been plotted as shown in Figure 2-7: Fig.2 Strength-temper temperature curve Fig.3 Yield ratio –temper temperature curve Fig.4 Elongation–temper temperature curve Fig.5 Percentage reduction of area–temper temperature curve Fig.6 Impact energy–temper temperature curve Fig.7 Hardness–temper temperature curve From Figure 2-3 can conclude that the impact of tempering temperature on the strength is notable, strength of 350℃ tempering is up to 1800MPa.
In a trend, elongation and reduction of area increase with fluctuation of tempering temperature, impact toughness increases with tempering temperature rises.
For 400℃ to 550℃ of tempering, elongation and reduction of area suddenly decrease but impact energy decrease not obviously.
