It can play an important part in soil and water conservation, regulate and storage water, the satisfied of carbon oxygen generator to maintain the cold temperate species diversity and regional ecological balance protection of national and Northeast Asia Eco security essential ecological functions.It is the main body of the terrestrial ecosystems of the northeast region, affect the redistribution of temperature and rainfall, the natural barrier of the important production base of commodity grain and livestock.
The rapid construction of eco-industrial development, and gradually formed Lint industry and eco-tourism-based eco-industrial system of ecological agriculture, ecological animal husbandry and aquaculture, ecological industry, forest resources-based economic model. 3.The importance of biological protection in the planning and construction process 3.1Eco-efficiency In Xing'an ecological function areas through the implementation of the biological conservation projects, to build a number of protected areas, the establishment of the sanctuary, and the reconstruction and restoration of natural ecosystems, the protection of the ecological environment has important significance.

Agricultural mechanization developed agriculture and animal husbandry stably, and provided a large number of labors for the development of industry and tertiary industry.
The United States has entered the stage of system mechanization and automation, not only crops production and harvest has fully realized mechanization, but also some difficult industries and works. 3.2 France France was one of the world food exporting countries that owned developed agriculture, higher agricultural mechanization level, wheat, corn and other grain production, livestock and poultry breeding have achieved whole process of mechanization.

One of that is by replacing TiO2 nanoparticle by nanorod (nanotube or nanowire) [2-3], thereby eliminating the grain boundaries between nanoparticles [4].
In other word, the number of nanorod over certain surface area is relatively low.

The samples are nanosize flake crystal grains.
In the chemical calculation rate structure [Mg6Al2(OH)16CO3].4H2O, hydroxyl piles up and constructs a certain number of octahedral structure spaces under the condition of the unchanged pH value in all reaction processes.

There are a number of potential solutions to this problem.
Coal ash characteristics Specific gravity Constrained grain size Non-uniform coefficient Cu (-) Coefficient of curvature Cc (-) d60 d30 d10 (mm) (mm) (mm) 2.08 0.5 0.055 0.004 11.20 1.33 Clay The clay in test is taken from campus of Northeast Dianli University in Jilin.

In this process, the precursor dissolves quickly in the alkaline medium and the crystal grain generates in the surface of the acidification zeolite in great numbers, indicating that the crystal quickly grows in this stage.

Such behaviour for the conductivity of samples in the high field region (10MV/m) is tentatively explained in terms of a set of barriers to the conductivity at the grain boundaries of the ceramic particles, in accordance with a Schottky barrier type conductivity: � � � � � �
 � KT exp
 where 
 are related with the number and the hight of the barriers.

However, the grain size decreased noticeably with the incorporation of silicate into the apatite structure (Fig. 3).
The first result was an increase of the number of cells on all the tested materials with the culture time from 3 to 7 days.

Combination of magnetic and elastic properties leads to a number of striking phenomena that are exhibited in response to impressed magnetic field.
Zhdanov1, G Morfill1, Levitation and agglomeration of magnetic grains in a complex (dusty) plasma with magnetic field.

In this area it firstly arises to the slips in the surrounding grains by influence of tensile stress activity.
If the number of impurities in certain area is bigger, it considerably decreases the cross-section of experimental sample, which transfers force, by which the tensile stress increases in certain area, which causes localization of plastic deformation in certain area.
