 Dear Sir or Madam:

  The purpose of this letter is to recommend Mr. Yi, a worthy candidate for admission to your graduate program.

  Mr. Yi have ever took my course "Introduction to Control". I was deeply impressed with him not only the good score "A" he got in the class but also thehighly active and devout attitude he learn Control Theory. Sometimes, he came to my office to ask me some interesting questions about the Control and System theories not mentioned in the autobiology of my class and to discuss the development and application of control theory in Science and Industry with me. He imagined this theory is truly an amazing subject. If people understand and use it very well, this world will get better. "Well!" I thought, " This young man is really like Control."

  Then he took part in my research "Design of Sinusoidal Oscillators Using the Theory of Variable Structure Systems" (published in the Int. J. of Electronics, 1992, Vol. 72, No. 1) to design the oscillator circuits. From simulating the circuits he designed with PSPICE to assembling the electronic elements. he shown me the enthusiam and hardily spirit in his work.When gettinga new idea or finding some questions,he always shared his opinion about how to overcome the error or improve the experiment results to me.After try-and-error and ameliorating the circuit many times, we finally got a refined but good-performance oscillator.

  Mr. Yi also got admirable grades in a couple of courses of control and systems, I truly believe he has strong learning capability and enthusism in this field. So I no doubt that he will become a good student in your esteemed department. Should you need any further information about Mr. Yi, please do nothesitate to contact me.

  Sincerely Yours

  XXX

尊敬的先生或女士:
这封信的目的是易先生建议,值得你的研究生课程入学候选人。
易先生曾经把我的课程“控制”介绍。我留下了深刻的印象,他不仅是好成绩“A”他得到了在课堂上的,但也thehighly活跃和虔诚的态度,他学习控制理论。有时,他来到我的办公室,问我有关控制和系统理论我的类autobiology中提到的一些有趣的问题,并讨论与我在科学和工业控制理论的发展和应用。他想象这个理论确实是一个了不起的主题。如果人们很好地理解和使用它,这个世界会变得更好。 “好啊!”我想,“这个年轻人是真的很喜欢控制。”
然后,他参加了在我的研究“正弦振荡器设计理论的变结构控制系统”(发表在诠释。J.电子,1992年,第72页,第1号)振荡器电路设计。他从模拟电路设计与PSPICE组装电子元件。他我的热情有所和hardily的精神在他的work.When gettinga新的想法或发现了一些问题,他总是分享他的意见如何克服错误或改善,me.After尝试和错误的实验结果,并改善电路很多时候,我们终于得到了一个精致的,但良好的高性能振荡器。
易先生也得到了令人钦佩的成绩在一对夫妇的控制和系统的课程,我才真正相信他在这一领域具有较强的学习能力和enthusism。所以,我不怀疑他会成为一个好学生,在贵部门。关于易先生,如果您需要任何进一步的信息,请不要nothesitate与我联系。
