T echnical English for Oil and Gas

Storage and T ransportation Engineering Since September this year, we have had a new course called Technical English for oil and gas storage and transportation engineering. Professor Liu is the teacher of this course and she is very well to us. In the teaching of Professor Liu, I get much knowledge and I fell very happy.

Now,let me write somethings about my profession with some personnal ideals.

Extensive Reading

①The title of the first paper I viewed is “Fluid and Hydraulic System”.As far as I am concerned,this paper mainly describes two important contents which are fluid and hydraulic system.

The former part of this paper gives an account of Fluid that is a substance which may flow.Its constituent particles may continuously change their positions relative to one another.Moreover,it offers no lasting resistance to the displacement,however great ,of one layer over another.This means that,if the fluid is at rest,no shear force(that is a force tangential to the surface on which it acts)can exist in it.

Meanwhile,fluid may be classified as Newtonian or non- Newtonian.In Newtonian fluid there is a linear relation between the magnitude of applied shear stresses and the resulting rate of angular

deformation.In non- Newtonian fluid there is a nonlinear relation between the magnitude of applied shear stresses and the resulting rate of angular deformation.

The after part of this paper is concerned with the hydraulic system. I think the ligament between the two sides is “Pascal’s law”. Because all hydraulic systems depend on Pascal’s law,named after Braise Pascal, who discovered the law. This law states that pressurized fluid within a closed container-such as cylinder or pipe-exerts equal force on all of the surfaces of the container. Moreover, in actual hydraulic systems, Pascal’s law defines the basis of the results which are obtained from the system.Thus,pump moves the liquid in the system. The intake of the pump is connected to a liquid source,usually called the tank or reservoir. Atmospheric pressure,pressing on the liquid in the reservior,forces the liquid into the pump.when the pump operates,it forces liquid from the tank into the discharge pipe at a suitable pressure.

②The title of the second paper I viewed is “A Discussion on Modern Design Optimization”. In this paper,the author focuses on the theory underlying some of the mathematical methods employed by design optimization procedures.

To begin with, this paper treats of the optimization techniques taking one with another. The integration of optimization techniques
