Statement of Purpose
(Space Sciences)
General Introduction
I began my undergraduate study in the Department of Physics at Central China Normal
University in September 1998. During the four years, I devoted myself to the
mathematics, physics and computer coursed such as advanced mathematics, classical
mechanics, quantum mechanics, statistical mechanics etc. It was my hop that I would
be able to build a solid foundation for my future research. My undergraduate study
was very successful and my overall GPA was among the top 5% in my class.
Academic Performance
After graduation in 1992,I was admitted by Peking University to pursue a Master’s
Degree in Space Physics. The three-year graduate study at Peking University was
fruitful. I took a number of coursed, such as Solar-terrestrial Space Physics,
Space Plasma Physics and Ionosphere Physics, etc. In order to enlarge my knowledge
background and to satisfy my curiosities to modern science., I audited and elected
many other courses for other majors like General Relativity, Group Theory and
Partial Differential Equations Simultaneously, I frequented the library to refer to
different kinds of professional journals, such as Physics Review, Journal of
computational Physic, Journal of Geophysical Research, Solar Physics, Astrophysics,
etc. I kept myself well informed of the latest developments in this field, and
developed my abilities to read and write English. To get a better understanding of
academic research, I attended space physics academic communication meeting in 1992,
and Geophysics Annual Conference in 1993 where many scientists delivered academic
reports. I realized that undertaking the research work offers many interesting
challenges, and I need to expand my knowledge in my field.
Because of my outstanding grades and academic performance, I was honored
scholarship in two consecutive years, one is Subject Prize in the 1992-1993
academic year, the other is Guanghua Prize the highest scholarship at Peking
University, in the 1993-1994 academic year.
Teaching Experience
At Central China Normal University, I took general education coursed, such as
Psychology, Education and Teaching Methods. At the last semester, I began my
teaching internship at high school. I taught my students clearly in aid of modern
experiment instrument, and was widely welcomed by the students.
I became a teaching assistant in FORTRAN LLANGUAGE for undergraduate students at
this semester at Peking University. In addition to the necessary FORTRAN 77 taught
by the major teacher, I presented the students a variety of computer knowledge in C
language, computer program design and computer software. I felt very pride when
most of my students can operate computer expertly at the end of this semester.
Scholastic Aptitude
At my second year graduate study, I began to work as a research assistant of
Professor Chuanyi Tu, a famous scientist in Space Sciences. He proposed the energy-
cascading theory in a new solar wind model, and was awarded VIKRAM SARABHAI prize
by COSPAR and ISRO. I modified his theory by considering the dissipation mechanism
of the Alfven waves for heliocentric distance R 10R sun and developed a two-fluid
model. The mechanism of solar wind acceleration is the basic problem in solar wind
model. The purpose of my recent work is to explore the mechanism of solar wind
acceleration and heating, and the mechanism of the heating of the corona. I want to
establish the energy-cascading heating effect tow-fluid solar wind model by
Alfvenic fluctuations, which can describe the radial evolution of power spectrum of
Alfvenic fluctuation. The model includes the solar wind equations and power
spectrum equation in the spatial and temporal. The FCT (flux-corrected-transport)
methods are used to treat the mass equation and the momentum equation. The heat
conduction equations as well as the power spectrum equation are treated by an
implicit scheme. I devoted myself to the research and have solved most of the
established problems independently.
This work is collaborated with Professor Hu at University of Science and Technology
of China (USTC). This October and November, I took the opportunity to come to USTC
to work directly under the guidance of Professor Hu, who is second to none for his
achievements in the field of Magneto-hydrodynamics (MHD) numerical simulation in
china. We discussed many questions about research theories and numerical methods.
To determine whether a steady state is reached in the temporal evolution of the
low, we need to examine some conserved quantities inherent in a steady-state
solution to see if they are conserved throughout the domain. Through several
weeks’ hard work in the Space Physics Laboratory of USTC, I achieved satisfactory
solutions. The mass flux, momentum flux and energy flux are constant within 5%,
0.5% and 3%. In addition, I also participated in their seminar about nonlinear
dynamics, and audited some coursed like chaotic dynamics. I realized that my collaboration with other university especially with USTC will give me a more solid
and broad background on mathematics and Physics, and may make it easy for me to go
into these fields of my later research.
Now, having experienced success and failure in my research work and studies, I have
possessed the capacity of carrying research independently and developed my own
working habit that somehow we seem to be successful. I believe I hold adequate
potential to be further developed. I enjoy my present study and work, which are
challenging and desirable. However, I am very eager to further my study in my chosen field up to the most advanced level in your institute. I love the research
work and have aimed at a life time career in science for a long time. Upon
completion of my study, I will return and make contributions to my homeland.
