Large plastic deformation, seriously work hardening, a large number of cutting heat, cooling difficulties and other problems will appear in the production process [5].
PVD coated cemented carbide inserts, usually with fine-grained carbide blade substrate material and high temperature resistant coating (such as nano-TiAlN,its nano-coating structure refer to Fig. 1), which make it not only has high toughness and hardness, but also has good thermal stability and chemical stability; its unique coating process make the cutter has a smooth surface and good wear resistance.

In order to keep the system at a constant medium conditions, we constantly change the medium to keep the nutritional composition constant (each media replacement may lose a small number of cells causing error due to the operation) and different replacement frequency analog different input speed of nutrients.

Besides, the contribution to the total mass transfer at the expense of grain-boundary diffusion need to be considered.
The maximum of number of mobile dislocations which can transfer the interstitials by the dislocation-dynamic mechanismin was found in the range of deformation 10-15 % [9, 10].

A numbers of author showed that some of the important trends have present regarding the relationship the relationship between mechanical properties and microstructure of Zinc-Aluminium alloy but it sufficient information available on the information on Zinc-Tin alloy.
The improvement in tensile strength and elongation could be ascribed by grain size increment.

(4) Other types of vibration isolation system: foam rubber, foam plastic, soft wood, felt, sawdust and fine-grained sand, applicable for small apparatus and instrument. 3 Design essential for vibration isolator [2] (1) Design the acting point of exciting force near the centroid of facility to prevent swinging; ensure that the sum of elastic moments around the centroid is close to zero, i.e. identical deformation, to stabilize the elastic support
(2) Arrange the springs symmetrically about the centroid, odd number of springs in each row, to facilitate adding or removing 1-2 springs during debugging.

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.

A minimum number of five specimens were tested for each experimental condition. 2.2 Sample machining.
As shown in figure 2, the white phases are ZrB2, the gray phase is SiC, but relatively small carbon black particles attached to grain boundary are not easily observed in the micrograph.

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.
