The annealing process leads to a phase-separation of nanocrystalline silicon dots and SiO2 materials.
Especially, the band gap of nanostructure system to compose of Si-nc dots embedded into its dielectric materials can be tuned by adjusting the nanocrystal size.
Sol-gel method is a simple technique at low temperature by using nanocomposite materials, used as a viscous medium through crystallites settle.

Third, positioning management is needed in the light of research results and the amount of such agricultural materials as seeds, fertilizers and pesticides need to be adjusted according to the distribution of spatial variability and local conditions in order to reduce investment, increase production, improve agricultural materials utilization and reduce environmental pollution [2].
Variable-rate controlling technology means that an agricultural implement with a computer, DGPS, and other advanced equipments installed automatically regulates the rate of some agricultural material fertilizing in the container on the basis of its land position.
A variable-rate controlling device includes either the equipment for controlling the flow rate of specific substances or for synchronously controlling the flow rate of more substances to make the running implement automatically change the amount of material input, furthermore, to achieve desired results.

Introduction Conventional process to manufacture wire to printed circuit board (PCB) has the shortcomings such as cockamamie production processes, high cost of materials, heavy pollution etc[1].
Experimental Materials.
Firstly, the conductive slurry was calcined at 150 ℃ for 1 hour on the surface of substrate.Secondly, the Resistivity was measured with the RTS-4 four-probe tester which made in Guangzhou Institute of manufacture of semiconductor materials.Thirdly, the conductivity was calculated according to the formula below I＝F(W／S)×F(D／S)×W×0.1

An Analysis of Colors Used in Gardening and Landscape Design Zhenglei Dong Huanghe Science and Technology College, Zhengzhou, China 2040488851@qq.com Keywords: landscape design, use of colors, gardening design, colors of landscape Abstract.
But in some rest areas or squares paved by rigid materials, the colors of buildings, opuscules, pavements and waters are the major colors while the plant colors come close in second.
But they are widely used in modern landscape and environmental color design, especially in design of modern industrial materials such as copper, stainless steel, titanium and alloy.
Generally speaking, silver materials such as stainless steel and alloy are often used in designing sculptures and opuscules that are rich in modern feeling.

It is chosen in the current task because of its good long-term durability and stability, as well as its compatibility with common polymeric materials, making them easily embeddable inside a composite structure without inducing significant weakening of the material.
Results and discussion The impact force exerted by the hammer is dependent on the material it hits upon.
