Compared to steel and titanium, high ductility of aluminium and its alloys enables shaping these materials at relatively low temperatures [1].
The resulting material is characterized by properties different from the properties of materials obtained by the conventional extrusion process.
Therefore, studies are being conducted to trace the stress-strain relationship in materials subjected to dynamic deformation [1].
The KOBO extrusion process carried out in two different variants produced materials of different structure and mechanical properties.

Useless heat from industrial and mining enterprises is transported without pipe through recovery and storage by Colin industrial and mining waste heat recovery and urban mobile heating system which deliver the stored- heat to the enterprises that need it for warm and hot water. 1.2 The advantages of the urban mobile heating system This system uses the heat storage materials which has its intellectual property rights.
After obtaining sufficient energy by the phase change materials it gradually changed lattice - phase changing.
Fig.4 Structure of the device of heat storage Low heat recovery has been carried on with purpose of saving energy and water sources, using a variety of high-tech which contained the Ministry of Science and Technology Innovation Fund, in dozens of central enterprises.
l Stability, security in recovery of waste heat; l The device is compact, small footprint and easy to access to the system; l Automatic discharge of the exhaust steam and gas in the mixed water; l Only when the system start or stop, manual switching of atmosphere between discharging and recycling; l Unattended, low maintenance costs and continuous operation of the life cycle more than 10 years. 3.2 Regenerative device characteristics Compared to the latent heat of regenerative material and the sensible heat regenerator materials, high heat storage density surpass other materials through the phase transition at constant temperature when release large amounts of heat.
Combined cycle plant efficiency increase based on the optimization of the heat recovery steam generator operating paraeters[J].International Journal of Thermal Sciences.2002,41(9):843-859 [4] S.H.

Introduction As the development of water conservancy,highway,railway and other foundation engineering constructions,various of secondary slope are formed,which induced irreversible destroy to nature vegetation ,generating several adverse impact on ecological environment.By the influence of external factors such as rainfall,high temperature,severe cold and etc,shear strength of bare slope decreased.Besides,when face to rushing flow caused by rainfall,there will be some potential disaster even collapse.Geocell is a new type of synthetic material which is used for slope protect.According to filling and grassing in cell for slope greening directly ,it can prevent the slope from rain drop erosion, decrease the impact energy of rainfall, reduce the speed of runoff along the slope, which can reduce the wash of rainfall act on the slope.what's more, slope will be mixed together with the environment after greening,developed roots of the plant will plunge into rock side slope, soil will be fixed

The reaction activity of 4-ethyloctanoic acid is weak, so 4-ethyloctanoyl chloride (EOC) was used as the starting material.
In the course of experiments, we found that reaction temperature, different mole ratio of materials and reaction time had some effect on the yield of benzyl 4-ethyloctanoate.
The mole ratio of materials has greater influence on the yield of ester, so the effects of mole ratio of materials on the yield were investigated under the reaction condition of a reaction time of 3.5h and a reaction temperature of 85°C.
Effect of different mole ratio of materials on the yield.
