机械工程专业自述范例（攻读博士）
资料来源：Accepted.com
Mechanical engineering is the foundation of industry.
It plays a key role in the national economy. It’s broad field including
general engineering, aeronautical, chemical and nuclear engineering, etc.
Provides a sufficient room of choices for me to realize the dream of
becoming a scientist or a mechanical engineer. It was with this fact in mind
that I decided to choose mechanical engineering as the major field of study
for both undergraduate and graduate career at Tsinghua University.
During nearly eight years of study at Tsinghua University, I completed a
total of 47 courses in undergraduate study, 14 courses in graduate study.
The major courses that interested me most included: Theoretical Mechanics,
Strength of Materials, Elasticity and Plasticity Mechanical Analysis of
Plastic Deformation Processes, Theory of Metal Forming, Computer Language
and Programming, Mechanical Design, etc… After graduation, I entered the
First Heaby Machinery Works (in northeast of China). During this period, I
became familiar with the design and manufacturing of some heavy machines,
thus furthering my interest in mechanical engineering. At the same time, I
found that many good ideas of design could not be put into existence because
of the backwardness in raw material quality and processing techniques. This
fact impelled the related areas and me to concentrate my research interest
on materials science and processing. Through careful survey, I selected a
subject about the quality control of heavy disc forging and took it as my
research subject for master degree. After over tow years of investigation, I
finally made a great innovation in the forging process, making the end
product rate increase from 50% to 90%. In the course of investigation and my
later working after graduate study, I also found some problems that are
common in mechanical industry. For example, how do cracks in products during
hot metal working generate and develop? How to avoid cracks? How do
non-metallic inclusions affect the properties of materials? How to control
the content, shape and distribution of inclusions in final products?
Solution to these problems will improve the quality of many kinds of
products. But they are often difficult to be solved because they include
knowledge of many disciplines and require many new research methods. I feel
that what I have learned is far from sufficient to tackle all the problems.
Thus I have decided to continue my education by pursuing a doctoral degree
in mechanical engineering in a highly industrialized country like the United
States.
I plan to complete my degree objective I 3 to 5 year and hope that I will be
able to further my knowledge I areas including Solid Mechanics, Materials
Science and Processes, CAD/CAM, etc… After completing my graduate study, I
will return to contribute my learning to my country. I plan to work as a
researcher of a teacher at an institute or a university.
