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.

One
of the characteristics of aluminium alloys is that a number of final strip properties are influenced
considerably already at very early process stages.
The same is true for all other variables, which describe a given material state, such as crystal orientation, state of dissolution, particle constitution, -size, grain size, etc..
A number of micro-models also interact where simultaneous reactions occur, e.g. the state of precipitation/solute level and nucleation of recrystallisation is strongly inter-linked.
In both models, a number of material models is incorporated in a fully coupled mode.

AlamarBlue assays showed that the cell proliferation of MC3T3-E1 preosteoblasts scaffolds were sixfold increase in relation to the number of the initial cells.
The scaffolds with zirconia showed a larger precipitation of HA on their surface than the samples without zirconia; furthermore, bar-like shape HA grains as well as cauliflower-type structure HA can be observed in Fig. 3.
Fu et al. [15]. showed that after 6-day incubation the MC3T3-E1 cells had tripled the initial number.

However, as the number of car has been increasing for many years, the passenger tire retreading is urgently needed.
In recent years, with the rapid increase in the number of car, the passenger tire retreading is urgently needed also.
And its main task is to use the ordinary tire grinding machine, profile grinding machine, automatic tire grinding machines and other equipment to abrasion damage, old rubber with much oxidation, and grind out the suitable carcass for prevulcanized tread, the best grinding grain roughness, binding with the renovating glue.

But in actual construction process, a large number of engineering practice shows that the seams between the insulation board and insulation board or wall with single energy-saving window plastic junction, or plaster layer has widespread cracks phenomenon, the partial condensation of moisture is also very prominent.
Sand: As the sand grain size distribution does not conform to the requirements, or silt content is bigger, it can cause dry crack.
Glass installed in every article, demand docking, accurate location, block number, location, conform to the requirements to ensure that it meets basic requirements of air permeability, water leakage and heat preservation etc.

Perfect iron has its atoms arranged in a bcc lattice structure, but in practice there are various defects in this metal such as vacancy, dislocation, grain boundary and void i.e.
L. i.e. reported their MD simulations of the effect of Cr on the diffusion of single, di- and tri-interstitials in Fe–10%Cr alloys with two Finnis–Sinclair-type potentials to model the the Fe–Cr alloys. [3] MD simulations were used to study the interaction between a SIA and an edge dislocation in Fe to clarify their behavior in the evolution of damage structure during irradiation, in the so-called production bias effect through one-dimensional migration to sinks and in the so-called dislocation bias.[6] There have been a great number of MD simulations reported to study 1 or 2 dimension defects of iron.
In order to eliminate translation energy and describe the thermal effect of the defect in the process of shock propagation, the local temperature without COM (center of mass) velocity was introduced in our study, which is calculated by formula (1) (1) (2) where k=Boltzmann constant, N=number of atoms in a specific cube, mi =mass of atom i, vi=velocity of atom i, Tcom is local temperature without COM velocity, Vcom is velocity of the center of mass of a specified cube and calculated by formula (2).

Although these formed primarily at grain boundaries, some intragranular
precipitates were also seen.

When add 2%Si, SiCw is straight, the rate of straight grain is high, the length of SiCw is 10~15μm, the diameter of SiCw is 0.1~0.3μm.
Melting point of Si is 1420°C, at 1550°C, it melted and fully spread, so it has positive role in promoting the (1), provide a large number of the active site of the whisker growth, make SiO get into the liquid easily through gas- liquid interface, when SiO reach a certain degree of supersaturation, nucleus take shape and deposite on the interface of liquid and substrate, with the continued supply of gas, nucleus growed continued along the direction of one-dimensional[3], therefore, SiCw produced well.
When the Si is overfull, because the growth space of SiCw is limited, too much SiCw contacted with each other and assembled, these reduce the number of SiCw.
