Introduction China is a big country of sugar production which annual output is nearly 100 million tons, ranking the third largest producer after Brazil and India in the world.What’s more, sugar cane is the main sugar crop in our country whose area takes up more than 85 percent[2] in our annual sugar crop area, and sugar yield takes up over 90 percent[1] in sugar total output.At present, China's production technology of sugarcane’s raw material is still at a low level, Sucrose production cost more than 70 percent[3] in production.After joining WTO, China's sugar industry is faced with the impact of raw sugar import quotas and tariff change,so market competition is very fierce.Our country now sucrose production cost is exorbitant,and sugar prices have no advantage in the international market competition.Therefore, improving sugarcane production technology level is an urgent problem to be solved,and the key to the problem is not only to increase mechanization of sugarcane production level
The transmission shaft use solid shaft whose material is 45 Steel.

Some countries control the price of global bio-energy raw materials [10], and manipulate the international raw materials market.
It not only increases the food production, but also provides rich raw materials for bio-energy development.
There are plenty of trees and flowers for urban greening and a large number of biomass materials.
If the materials developed reasonably, abundant raw materials and fertilizers would be provided for the development of bio-energy and circular agriculture, and that will have a wide prospect for development.

Actually, attention has been focused on the possibility of using them as reinforcing materials on masonry structures.
Mechanical Characterization of Materials The materials considered in the experimental program consist of uni- and bi-directional jute, hemp, flax, basalt fiber.
Basic Materials Fiber-reinforced materials are composite materials made up of two or more phases that have distinct properties from each other, and this implies that the system has different characteristics from its constituents taken individually.
The experimental results of the mechanical characterization tests of the basic materials were carried out in the Materials and Structures Engineering Laboratory of the Civil Engineering Department of the University of Calabria.

Biocomposite materials have been developed in order to combine the properties of bioactive material with the better mechanical properties of a second phase.
Thus the densities of the sintered composite materials are lower then the pure state of the materials and this leads to perfection for them to be used as prosthetic devices.
This study deals with the effect of Ti content and sintering temperatures on improving HATi biocomposite materials.

AE is a common physical phenomenon, and the signal strength of AE of plastic deformation or breakage of most metal materials is weak, and ears can not hear it.
For the components or materials in movement, AE signals can be collected, and analysis can be conducted on the signals combining with AE physical features of materials, so that the potential defects of materials can be detected[2][3].

However, nearly all of the investigations were focused on the microstructures evolution and grain refinement of the materials.
Static toughness represents comprehensive mechanical property of materials, and indicates a combination of materials' strength and plasticity [16-17].
The static toughness U of materials can be calculated by ∫= t dU ε εσ0 (1) where σis the flow stress and tε is the total strain at fracture.
