推荐信控制和系统案例中英文范文介绍

尊敬的先生或女士:

这封信的目的是推荐Yi先生,他是你研究生入学的好候选人。

Yi先生上过我的课程“控制导论”。给我留下深刻印象的他不仅成绩好”“他在课堂上也高度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一些有趣的问题,关于控制和系统理论在我班的个体生物学不提及和讨论,我在科学控制理论和工业应用的发展。他认为这个理论确实是一门令人惊异的学科。如果人们理解和使用它非常好,这个世界会变得更好。”好!”我想,“这个年轻人真的很喜欢控制。”

然后他参加了我的研究”设计的正弦振荡器使用理论的变结构系统”(发表在电子技术,1992,72卷,1号国际J.)的振荡器电路的设计。从模拟他设计与PSPICE组装电子元件的电路。他对我的热情和刻苦的精神在他的工作。当听到新的想法或发现一些问题,他总是把他的意见如何克服错误或提高实验结果的我。经过尝试和改进电路很多次,我们终于有了一个精致但性能好的振荡器。

Yi先生也得到了令人羡慕的成绩在几个控制系统课程,我真的相信,他在这个领域有很强的学习能力和热情。所以我毫不怀疑他会成为贵系的好学生。如果您需要任何关于Yi先生的更多信息,请随时与我联系。

你真诚的

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
