自己写了两遍,同学帮着改了一下,已经用这个申完5锁了,但总觉得有些地方不合适,希望大家能提提意见,我重写也可以。
经历写的比较少,写研究兴趣写的很多不知合适不。. 鐣欏鐢宠璁哄潧-涓浜╀笁鍒嗗湴
Statement of Purpose

I was born in an age when aeronautical and astronautical technologies enjoy great development. Mars rovers Opportunity and Curiosity enlarged human's coverage to Mars. Hypersonic Aircraft X-43A increased the highest air-launched aircraft speed to nearly Mach 10. Enthusiastic about these advanced technologies and attracted by the incomparable charm of universe and flight, I choose aerospace engineering as my major and hope to make my part of contributions to its development. I wish I could become a designer or expert who can help with large and epochal research projects in the future.

I’m going to acquire my bachelor’s degree of Aerospace Engineering at *** in the next semester. Three years ago, by virtue of excellent grades in college entrance exam, I entered School of *** at***University, a special college admitting only 55 students from nearly 3000 freshmen. Here not only did I take professional courses concerning Aeronautics & Astronautics, but my mathematics and physics foundation got greatly strengthened by taking the basic disciplines opened up specially to bachelors of science. My exceptional records in courses like Mathematical Analysis, Advanced Algebra could prove this. Besides, having found my research interests early, I have learnt hypersonic and high temperature gas dynamics, rarefied gas dynamics, Fortran language programming, quantum mechanism, electrodynamics and etc. by self-learning. It’s a pity that my knowledge in these areas could not be shown on my transcript. Nonetheless I believe my theoretical foundations are competitive with other bachelors’ and will be an advantage for my further graduate study.

In the past three years, I also participated into some academic research and practices besides learning. I joined the *** lab in my second academic year and am tutored by ***. In the last year, cooperating with my senior schoolmate, I did some CFD calculations on supersonic flow over a flat plate for the project Research on a DSMC Approach and Its Application to a Two Dimensional Simulation of a Sharp Leading Edge under Mach 25. Now I am conducting a project named DSMC Simulation of Hypersonic Rarefied Gas Flow over Typical Shapes, which aims at creating a 2D-DSMC program compatible with complex grid and analyzing hypersonic rarefied gas flow over typical shapes. Although some related knowledge hasn’t been learned before, I’ve finished several subroutines and the project progresses well. I have also participated into the design and production of two unmanned aircraft vehicles. One is the Quad Tilt Rotor of our college workshop. I was responsible for the electronic platform and the design and production of horizontal tail. I wrote the automatic control program without any foundation in 2 months. Finally, we won the third prize in 23th Fengru Cup Competition with this UAV. The other is Zhedao of my interned company. Through these practices, I got a preliminary understanding of flight vehicle design and was familiar with commercial software like Fluent, Gridgen, Autodesk Inventor and etc. Nonetheless in comparison, I like academic research better.

My keen interests include the research related to hypersonic flow, CFD and fluid mechanics. The reasons for these are multiple. . 鐗涗汉浜戦泦,涓浜╀笁鍒嗗湴

For the hypersonic flow, I think it is one of the research directions with the most practical significance. It is closely related to cutting-edge technologies including high speed propulsion, planet entry and etc. The improvement of it will greatly benefit both civil and scientific applications. One typical example is the hypersonic aircraft, which saves both time and fuel with its unbelievable speed. However, related theories including thermal and chemical non-equilibrium, real gas effect, boundary layer transition, slip and rarefied flow and shock interaction still need to be perfected in order to make accurate simulation. Nobody could forget the tragedy of Space Shuttle Columbia, which brought seven astronauts’ lives away during re-entry just because of the damage to the heat shield material. Thus I do hope to devote my intelligence to the research of hypersonic flow in case the tragedy happens again. UCLA’s Hypersonic and Computational Aerodynamics group led by Professor Zhong, Xiaolin is my desirable lab. We have the same research interests and I have accumulated basic knowledge for his several research topics. The last but not the least, we’re both Chinese, which might make it easier for us to cooperate.

CFD is also my interesting area. With these years' learning, I realize CFD is not only a type of science to explain the physics nature, but also a useful and economical tool to solve engineering problems. Despite the fact that it has been developed for only a century, it has shown significant potentials in its abilities to replace some expensive or infeasible experiments. However, there still exist problems like turbulent modeling, grid effect, high-order scheme and limitations such as the simulation of rarefied gas flow and slip flow for CFD. I’d love to contribute to research including algorithms study and engineering application in the future.

Fluid mechanics, especially turbulent and transitional flows, is another research interest of mine. There is no doubt that turbulent and transitional flows are the top world’s problems. But their progresses including transition control, turbulent mixing and combustion will greatly benefit engineering as the catalyst. Aviation airplanes like A380, B747, and the most advanced B787, which both possess more economic efficiency and comfortable travel experience, are just typical examples. Indeed, UCLA’s Turbulence Research Group led by Professor Kim and Simulations of Flow Physics and Acoustic Laboratory led by Professor Eldredge attract me so much. Professor Kim’s experiences in numerical algorithms for turbulent study and his cutting-edge research make me believe my research skills and knowledge will both be improved under his instructions. And Professor Eldrege’s broad research directions including bio-fluid and computational studies interest me because in my opinion, the study of fluid mechanics should be applied in both Aerospace Engineering and other areas in our daily lives

In summary, I hope I could do some research related to hypersonic flow, turbulent and transitional flow based on numerical simulations or the algorithm studies of CFD in the future. Once I’m admitted by UCLA, I’ll endeavor to master the necessary knowledge and have my potentials fully tapped under the professors’ instructions. The ultimate degree I will pursue is Ph.D. of Aerospace Engineering. I'll try my best to get the opportunity to continue the PhD study in UCLA. I wish through the cultivation of scientific abilities, including the discovery and the analysis of problems, my contributions to a specific field can be made before I am graduated. When I finish my Ph.D. degree, engineer of an aeronautical technology company or faculty of a university are all my desirable jobs. It is the participation in the development of aerospace technologies that makes one of my greatest desires.. 涓浜-涓夊垎-鍦帮紝鐙鍙戝竷

I sincerely hope the graduate admission committee could consider my application seriously and make me a member of the prominent school, the University of California, Los Angeles.

嗯~可能有点中文式思维了,我再想想。现在主要是感觉研究兴趣堆得有点多,另外开头没什么亮点

鏉ユ簮涓浜.涓夊垎鍦拌鍧.
我觉得开头如果没有亮点不如精简一点好,不要tell story没有意义,最好是每句话都能表达一些思想,套话可以省略,我觉得最后一句即使是中文也有点不是很妥当你想评委会会愿意看到:我诚恳的希望你们能认真的审阅我的材料(大概这个意思)的这种话,感觉好像不说这个话他们就会马虎似的……兴趣我没有仔细看,因为不是一个专业的,但我觉得不用每个都写这么长,除非你对每个领域都能发表自己的见解(比如一些最新的研究成果),或者仔细读过每个教授的文章能说出个所以然来(比如你认为他们的哪个观点怎么怎么样),否则看起来很空洞,还占字数,不如把开头那些概述都省略了,毕竟committee不需要你来teach他们,而是需要你表达清楚这些方面和“你”有什么关系(做过什么研究?读过什么论文?有什么实践经验?上过什么课程?)总之就是为何你喜欢他们passion从哪来,要看起来有说服力不是太容易

楼主忘了**掉 Fengru Cup 啦
“The last but not the least, we’re both Chinese, which might make it easier for us to cooperate.”这个还是算了吧。。
中间三段关于兴趣的话,我觉得除非是特别有见地的内容,否则还不如展开写一写自己的research或者intern吧,不能说因为这个方向好或者问题多然后自己就感兴趣,还是从以前的工作细节结合事实说话吧
另外,CFD啊DSMC啊第一次出现的时候要不要给个全称呢,虽然大家都知道是啥。。. more info on 1point3acres.com
