The polymer emulsion in the component used as adhesive could connect the cement hydration products’ grains.
It was even replaced by a large number of coalescent leaving unstable emulsion[3].

Polishing disc materials employed were straight grained cedar wood, carbon for electrode use, mild steel, quartz glass. 765 1 3 42 Fig. 3 Hydration polishing setup diagram 1:Vapour generator; 2:Sapphire substrate; 3:seal cover; 4:loading system; 5:Vacuum cup; 6:steam nozzle; 7: temperature control system; 8: polishing disk Results and Discussions As polishing rate of sapphire is related to steam temperature and polishing disc material.
From spectrum of H2O molecular, we can see that in the range of 3600-4000cm-1 in wave number sapphire combine with H2O molecular.

Such configurations cannot be used by other methods, or are associated with a large number of difficulties.
The coating synthesized from the standard target is characterized by a mild-grained structure of equally-sized granules of similar shape, with an average granule size of about 40±5 nm, in the presence of significantly larger fragments ranging in size from 200 to 350 nm.

Surface studies in UHV require the use of large single grains (few mm at least).
Most CMAs have a non-congruent melting and the growth of single grains is not an easy task.
As a result, only a limited number of systems have been studied so far.
The number of surface studies on periodic CMA is more limited so far.
Moreover, no effect of surface orientation or grain boundaries on the final (saturated) state was evidenced when comparing single grain Al63Cu24Fe13 and hot isostatically pressed (multiple grain) Al66Cu22Fe12 samples.

Laminated templates electro-deposition (LTE) is a new manufacturing technique aimed at a highly precise and low-cost fabrication of metallic structures through a number of planar template-patterned depositing.
Since a number of planar depositing are performed in turn, the surface quality of one single depositing will determine whether the next round runs well and what level of precision the finish part can have.
Therefore metallic grains forming here enjoys a higher possibility to grow into protuberances and cluster-like crystal with big size at an over-increased growth rate[4].

A number of variables are investigated in order to determine how they affect the cavitation resistance of the welded joints, including mechanical attributes, welding parameters, and microstructural features.
FSW has a number of benefits, such as decreased distortion, enhanced mechanical qualities, and better microstructural features in the welded joints.

Apart from this, the elimination of grain and oil-vote system, the establishment of housing system and so on, all of which have contributed to provide a greater free corridor for the flow of urban-rural migration.
Among them the rural elderly empty-nest households has 11.2 million, accounting for 71.58% of the total number of the elderly empty-nest households.
The large number of migrant workers returning to the countryside, however, has caused a shock to the balance in the local employment situation, which was already weak.
The pattern of the original village and township enterprises economy has been weakened significantly in a number of coastal cities already.
The fundamental one is that it’s located in the Yangtze River Delta economic zone which enjoys a number of economic priority policies.

In the 21st Century, the increasing economic globalization, technological revolution, and economic restructuring not only makes great changes to the production and living styles of people, but also causes a number of social and environmental issues, even deterioration of the ecological environment.
(6) Indicators related to social benefit (B6) ① Employment indicator (C61): (9) Wherein: Sli refers to the proportion of employment in the i industry, and Li refers to the average number of employees in the i industry.
The lakeside hilly area beside Poyang Lake may, based on the terrain and landform, develop the comprehensive development model integrating “top for forestry, middle for husbandry and bottom for agriculture” and develop the ecological mode of “forestry-husbandry-grain and forestry-fruit-trade”.
The ecological model of “swine-pond-fruit and fishery-grain-vegetable” is applicable to ecological economy in the countryside courtyard.
The Poyang Lake Zone will integrate the agricultural production base, modern ecological agriculture base, grain production and increment base, green and organic food production base. 3.3.2 New industry Poyang Lake needs to develop new industry.
