美國留學申請書樣本

申請專業:金融工程

在我看來金融工程是一種創新、創造技術,一種對金融工具、金融手段和系統的創造和創新技術,一種平衡收益和風險的技術.它包含了數學,計算機,金融方面的知識,是一門充滿了趣味的交叉學科,而數學知識和數學模型是這個學科中必不可少的核心內容:馬科維茨的投資組合選擇理論,夏普的資本資產定價模型,Black-Scholes的期權定價模型以及考克斯等人的“二項式”模型正是這種核心地位的體現。

In my opinion, the Financial Engineering is a kind of creative technology to the Financial Instruments, Financial Means and system. It used to balance the benefits and venture as an interesting interdisciplinary subject. It covers many fields such as mathematics, computer science and finance, in which the mathematics and mathematical modeling are the two main aspects of the Financial Engineering. The Investment Portfolio Theory of Markowitz, the capital asset pricing model of the Sharp, Option Pricing Model of Black-Scholes and “Binomial” model of Cox can best reflect the critical position of the two subjects.

我有幸選擇了數學與應用數學這個專業,在三年和它的接觸瞭解中,使我對數學,尤其對數學建模有了較深的理解和體會。(記得第一次去聽清華大學XX系姜啓源教授的講座,他在講座上舉了一個“現實生活中的數學”例子:“1公斤面, 1公斤餡, 包100個餃子;若餡比 1公斤多, 應多包幾個, 還是少包幾個呢? ” 是這個生動、形象、富於生活氣息的包餃子問題把我領進了數學建模的世界。)

I am glad to choose mathematics and applied mathematics. Three years’ study had deepened my understanding of them, especially of mathematical modeling. (It still occurs to me when I went to attend the class of XX department given by Professor Jiang qiyuan in Tsinghua University for the first time. “1 kilogram of flour added with 1 kilogram of stuffing can make 100 dumplings, but what if the stuffing is more than 1 kilogram?” He used a very simple, vivid and interesting example which aroused my interest and led me into the mathematical modeling world.

第一次和數學建模親密接觸是在05年的暑假,我有幸參加了學校組織的數學建模培訓。經驗豐富的數學老師們通過實實在在的例子告訴我們什麼是數學建模。給我印象最深的是一個關於SARS的例子:2003年,SARS爆發並在世界範圍內傳播,嚴重影響到我國經濟發展和人民生活,定量的研究SARS的傳播規律並建立數學模型預測和控制傳染病蔓延成爲數學工作者必須解決的問題……於是Logistic迴歸便成爲我永恆的記憶。爲期2周的數學建模培訓,給我留下的不僅是一個個經典的數學模型,更重要的是一份澎湃的激情和一份冷靜的思考:數學和數學建模是人類的守護神,因爲有了她的存在,人類的生存和發展纔有條不紊的繼續着;那麼當SARS病毒肆無忌憚時,當AIDS病毒肆意侵蝕人們肉體時,一個熱愛數學、熱愛數學建模,更加熱愛生命的人能夠做些什麼?

The first time I kissed the mathematical modeling was in the summer vacation of 2005, when I got a good opportunity to attend the mathematical modeling training organized by our school. Seasoned mathematics teachers told me what on earth the mathematical modeling is through some existing examples, in which the one about SARS impressed me most. In 2003, SARS broke out and shrouded rapidly to the whole world, which imperiled our economic development and people’s living. Therefore, study on its spreading regularity and building the mathematical modeling for predicting and controlling its extension had become the “Archimedes Heels” for all mathematicians… So, the Logistic regression has been carved in my memory. Two weeks’ training has presented me with a kind of passion and calm thinking much more than just those classical mathematical models. As the patron saint of our human-beings, the existence of Mathematics and mathematical modeling are maintaining our subsistence and development. Then, when SARS ran riot, when we are suffering from the pain of AIDS, what can I do as a mathematics and mathematical modeling lover who loves life so much?

懷着這份激情和思考,在大二的秋天,我第一次嘗試了運用數學建模的知識去解決實際問題,我和另外兩名隊員代表學校參加了全國大學生數學建模比賽。比賽要求結合數據對長江水質做出定量評價,分析各地區的水質污染;並對未來長江水質污染髮展趨勢做出預測分析,制定污水處理計劃。長達17頁的數據和多個評價指標對我們來說着實是個挑戰!究竟應該選擇哪些數據?怎樣綜合考慮多個指標?我們嘗試了近一天,推翻了以前建立的種種模型,有好幾次都被弄得想要放棄,是隊友間的相互鼓勵的力量和鍥而不捨的精神讓我們最終找到了自己滿意的模型:綜合指數法模型評價長江水質,既體現水質的各種評價因子,又能反映主要污染物對水質的突出作用;通過多元線性迴歸擬合預測未來水質污染,建立線性優化模型,制定污水處理計劃。我們小組的參賽論文獲北京市二等獎。三天三夜的建模經歷,那份澎湃的激情已經漸漸平息,取而代之的是更加冷靜的思考:數學建模創造、創新,成功地解決問題依賴於紮實的數學基礎知識和過硬的數學建模能力;依賴於不拘一格的創新思維和創造能力;還依賴於對多方面知識的瞭解和積累。

Pocketed with this passion and thinking, I tasted to use mathematical modeling into practice and solve the practical problems by attending the National College Mathematical Modeling Contest with the other two schoolmates on behalf of our college. It required us to evaluate the water quality of Changjiang River according to the data, through which we had to analyze the water pollution in every region and predict the trend of it in the future. Finally we had to bring out the plan against it. It was really a challenge for us towards flood of data and estimations as long as 17 pages. We tried almost a whole day only to filter those data and take the evaluations into comprehensive account. Pulling down various models we had built before, we were so defeated that we wanted to give up many times. However, we finally found the satisfactory model thanks to our encouragement to each other which armed us with full strength to go managed to evaluate the water quality by Composite index model, which could not only represent the evaluation factors, but also reflect the main impacts of the contaminations to the water pollution. We predicted the future water pollution through multiple linear regressions fitting and brought out the plan against it by building linear optimization model. Finally, we got the second prize in Beijing for our thesis. Three days’ and nights’ modeling experience had cooled our passion and gave us even more calm thinking instead. The creation of the mathematical modeling, along with the successful solution to the problems through it lied on the solid mathematics foundation, strong modeling ability, accumulation of the knowledge on different fields, unique creative ideas and creativity.

參加數學建模比賽的經歷更加激發起我的學習興趣,使我在學習數學理論的同時更加註重它們的應用性。除此之外,我抓住一切可能的機會再次參加實際的數學建模。大三的上學期,我有幸參加了爲期3天的電工數學建模實習:給某大型運動會比賽項目排序。由於對圖論知識很熟悉,我很快將問題轉化爲尋找最佳Hamilton迴路。接近87億種不同的排序的數據量,比上次的全國數模競賽更大,我的算法運行時間相當長而且運行的結果也很不理想。這種情況的`發生不僅僅沒有打消我的積極性,反而使我的情緒高漲,這是人生中難得的自我考驗,自我提高的機會!通過查詢資料改用遺傳算法,運行時間和結果都大大提高.最後成功地完成這次實習.這次實習給我的感觸很大,一個數學模型是否能夠完美地解決實際問題還要考慮其運算成本,實際問題不僅需要一個成功的模型還需要一個快速有效的算法。

The experience from this contest further aroused my interest in mathematics. I began to pay more attention to its application as well as learning the theories. In addition, I tried to catch every opportunity to take part in the practical mathematical modeling. My efforts finally rewarded when I was in the first term as a junior. I had a chance to participate in the 3-day electrician mathematical modeling practice-----classifying the sports programs for a big sports meeting. Being familiar with the Graph Theory, I immediately found the way to solve the problems by seeking the best Hamilton circuit line. Facing the nearly 8.7 billion data files with different orders much more than that on the National Mathematical Modeling Contest, I spent a long time on Algorithm without any perfect result. I wasn’t defeated towards this case, but so excited instead that I could have such a chance to challenge and improve myself. Looking up dozens of files, I finally made a perfect end of the practice by using the Genetic Algorithm into full account. It needs both a successful model and an effective arithmetic to solve these problems. , which largely shortened the operation time and improved the operation result. I learnt a lot from this practice. I came to know that to build successful mathematics modeling that can effectively solve the practical problems, we must take the operation cost

電工數模實習結束後,濃厚的學習興趣和電工數學實習的教訓促使我和數學系、計算機系幾名同學共同籌劃並創建“數學建模沙龍”,將計算機算法和數學模型共同作爲沙龍的主題。每週二下午,我們會組織有興趣的同學一起,以傳授經驗、分享心得、共同思考、共同討論的方法學習和交流數學思想和算法。傳統的運輸問題、儲存問題和新興的模擬退火算法、螞蟻算法都曾成爲我們的討論話題。通過這個活動我從數學系和計算機系的同學身上分享了更多的知識,他們的思維方式,處理問題的方法!到目前爲止這個活動仍然在進行着,參加的人數也越來越多.帶動了學校的一個學習熱潮,我爲此感到非常的興奮!

Summarizing my failures in the mathematical modeling electrician practice and proceeding from my interest in this field, I began to think of collaborating on the “Mathematical Modeling Saloon” with several students from mathematics and computer departments, taking the Computer Algorithms and mathematical modeling as the two themes of the book. Every Tuesday afternoon, we would organized those students interested in this field to study and exchange the ideas and arithmetic by imparting experience, sharing what we learnt, pondering together and discussing with each other. Both the traditional transportation & storage problems and the modern Stimulated Annealing Arithmetic (SAA), Ant Algorithm have ever been the topic of our discussion, from which I have learnt many thinking styles and methods to the problems from the students both in mathematics and computer department. So far, I am excited to see that this activity is still in the wind with more and more participants and it aroused a learning upsurge in our college.

在老師的推薦下,大三暑假,我參加了邢永麗老師的教學改革項目——“提高數學課堂教學質量”的結果分析。04-05年,邢老師在她和其他幾個數學老師的任課班級上做了課堂互動的教學實踐,其數據大多以調查問卷等文字形式出現。此模型的特點讓我馬上聯想到模糊數學定量分析模型,但敢於嘗試新模型的念頭讓我最後選擇了AHP層次分析法。通過量化數據,應用AHP層次分析法定量分析老師的綜合素質、授課技巧等因素在師生互動、提高數學課堂教學質量中所起的作用,得出教師的授課技巧和課堂問題設置在課堂互動中所佔分量最重的結論,並和邢老師合作完成《層次分析法在課堂互動教學效果評價中的應用》論文,邢老師和我對論文都非常滿意,已向多個期刊投稿並有望發表。

Recommended by my teacher, I have participated in the Teaching Reform Program of Mrs. Xing yongli----the results analysis of “Improving the mathematics teaching quality on class”. Mrs. Xing, along with some other mathematics teachers experienced the class mutual activities in 2004 to 2005 with the character data files in form of paper investigations. For this style of data files, I finally used the Analytic Hierarchy Process (AHP) as a creative challenge instead of the fuzzy mathematical quantitative analysis models, which firstly knocked my mind. By quantitating data and using the AHP, I succeeded in analyzing how the overall quality of the teachers and their teaching skills work in improving the mathematics teaching quality on class, from which we got the conclusion that the teaching skills and the way to put forward questions on class play the most important role in the class mutual activities. Besides, Mrs. Xing collaborated with me on the thesis named “The Application of Analytic Hierarchy Processinto the Evaluation of Class Mutual Activities”. Both of us were satisfied with this thesis and contributed it to many presses to be published.

和數學建模一樣,金融工程的靈魂是創新思維和創造能力,而數學和數學建模知識在金融工程的應用更讓我對這門學科充滿了興趣;更s重要的是,金融工程技術能給人們的生活、社會的穩定、國家的發展做出重要貢獻,我想這個也更加符合我學習數學建模的初衷。

Similar with the mathematical modeling, the soul of the Financial Engineering is also the creativity. Therefore, the perfect application of the mathematics and mathematical modeling into the Financial Engineering once more surged my enthusiasm in this field. Furthermore, the Financial Engineering plays the important part in people’s living, social stability and the national development, which is my original intention to choose this field I think.
