Introduction There is a close relationship between seawater hydraulic drive technology,ocean development needs and the development of science and technology,meanwhile the research began in the sea water pump.
It is the Huazhong University of Science that first carried out the water hydraulics research in China and it majors in high water based hydraulic fluid and its components and systems work.
In recent years, Zhejiang University put a lot of human resources , material and financial resources to engage in water hydraulic technology research, and had achieved some certain results [1].

The test bench can work well under the condition of the variable speed and angle, and even under different structural parameters and different conveyed materials.
To solve this problem, the screw conveyor test bench can work in the case of variable angle, variable speed, and multi-factor for the screw conveyor of different structural parameters and different materials.
The experimental data under different inclination angles coefficients, different filling coefficients, different friction characteristics, different transport characteristics of different materials are not enough.

The use of edible food materials brings about a food-fuel crises and ethical issues about food security [17].
There are great concerns that the use of edible vegetable oils and animal fats for biodiesel production is not feasible because they are more expensive and compete with food materials in the long-term.
In light of this, research focus must be intensified to seek oil bearing plants that can be used as raw materials for biodiesel production.

Experimental Program Materials Characteristics.
Figs. 3 and 4 show TGA curves for fresh BOFS and aged BOFS materials, respectively.
However, this value changes due to different chemical compositions and the nonlinear mineralogical phase of BOFS materials.
The authors also appreciate the ArcelorMittal Temirtau steelmaking plant for supporting the raw materials used in this work.

The equipment has three driving units, fitted with electric motors: the driving unit no.1 (0.75 kW), provides a vertical movement of the FSW tool, the penetration speed of the pin tool in the materials, and the pressure of the tool shoulder on materials, after the following operating procedure: - descending of welding tool – contact between the pin tool and welding materials; - penetration of the pin tool on welding materials; - pressing of tool shoulder on the welding material surfaces; - the welding process ( the driving unit no. 1 is not working);- removal of the welding tool form the weld material.
In this point the tool shoulder is in contact with materials which need to be welded.
The result of FSW welded of AA2124/SiC/25%p-T4 metal matrix composite plates have shown that these materials can be welded by this process even at high tool transverse speed.

Though the transport characteristics of cementitious materials has been reported by many researchers[3,6~8].
And thus the repair materials system is confronted with serious durability problem.

Since the simulation model consists of two different geometrical and material elements we have defined the material for every structural element separately.
This definition consisted in selecting the material generated by us.
