太多了吧。看看这个：
我打算申请的是
联合培养博士生，今年博二。昨天，我刚收到外方导师的
邀请函，申请的学校一般，但对方导师是我们领域的大牛。在***有很多同学要我的邮件，看来大家对这比较关注。因此，我把我的申请过程在这里整理一下，顺便把通讯邮件附上。
原来担心对方名气太大了，恐怕不要我。也听别的同学说，这一步是比较耗时间的。所以开始时，我做好了被拒的心理准备。10月18日发出我的申请邮件，打算没有消息一
周后再发下一封申请信。申请函的内容如下：
Email 标题：Application letter for XX from Harbin Institute of Technology in P. R. China
Dear Prof. XX:
I'm XX, a 2nd year PhD candidate from Harbin Institute of Technology, Harbin, P. R. China, supervised by Prof. XX. And I ever contacted you for the password of your papers in the last time. I'm supported by a Chinese National Fund, which will support those PhD candidates in China to go abroad to some world class Universities of their fields. This programme will cover all living cost I need in USA. After I read a lot of papers of my research area, I understand that you are working on MAX phases and have published quite a lot of high level scientific papers. As such, you are the leading researcher in XX in the world. I find your area fits me well, so I write to you to see if you can give me a chance to study in your school. My CV and published papers have been attached.
My research area is mainly about MAX phases. I have published 5 papers in the journals including J. Mater. Res. and Solid State Commun. In addition, 2 papers were submitted. And now I'm doing XX. I am not applying a full time PhD programme, and this programme is a short time (12-24 months) co-education experiences more like a visit scholar programme. This programme is a new type of co-educate PhD programme supported by China Scholarship Council. The study period abroad varies from 12 months at least to 24 months at most. I have to accomplish my doctor degree back to my school (Harbin Institute of Technology), so I'm not supposed to acquire my doctor degree at Drexel University.
And this programme runs like this, students meet the application requirements can apply this programme, and my University and research area is among the main supporting Universities and areas. Students must acquire an official invitation letter from the prospective tutor/University. Therefore, all I need is an official invitation letter from you (or your University). The date of enrollment I'm considering is September/October 2010. In order to make sure I can catch up with the next year's programme, I have to prepare all the application stuff (including your official invitation letter) before January, 2010. And because it will cost about 1 month to mail your invitation letter from USA to China, so I really hope you can respond me
as soon as possible to make sure I can receive your letter before the winter vacation this year.
And if you can't make this decision or you have a better recommendation whose research areas fit me well, please inform me.
Really hope to hear from you as soon as possible!
Yours sincerely,
但是没想到，我的这个过程出奇的顺利：在电子子邮件发出的三天后，大牛给我回信，非常高兴的接受了我的申请，回信如下：
Dear XX,
My apologies for late response. I am delighted that you would like to get your PhD from Drexel University. Your experience with the XX certainly makes this a perfect fit since as you noted my group is one of the leading groups in the world in that area. As for the invitation letter, if you would not mind, pls draft one that says all the correct things and send it to me. This way would greatly speed up the process. Looking very much forward to having you join my group.
看到回信后，我非常高兴，就赶快给写好了邀请函草稿。用的是我同学去年申请用的邀请函，把个人信息发改了一下就发过去了，邮件如下：
Dear Prof. XX,
Very thanks for giving me the chance to study in your group! The draft of invitation letter under the requirement of China Scholarship Council (CSC) has been attached below. And the bold part of the draft could be replaced or modified. It should be noted that the invitation letter must be printed on the formal letter paper of Drexel University, with your handwriting signature, and then please send it to me by express delivery (CSC needs the original one).
In addition, we need to formulate a research plan for the PhD joint training program in your group. What's your opinion about it? If you would not mind, I will also draft one to you. If possible, I hope that it can be mailed to me with the invitation letter as mentioned above.
Your reply is appreciated!
到这一步了，基本完成了和国外老师间的联系，昨天下午拿到了邀请函和培养计划。
我申请的经验就是对申请要有针对性，对自己本领域课题组要比较熟悉，找与自己研究方向相近的，这点就能和国内的工作联系起来，对联合培养的博士很重要。方法可以通过看文献，参加学术会议等。另外一点很重要的是本人要有前期工作量，有发表出的论文是比较好的。拿我自己来说，我发表的五篇论文是起了很大的重要。
我使用的联合培养计划框架已经上传到附件，是我同学给我的，他已经申请联合培养成功后出去了。所以，这个应该是满足
留学基金委要求的。
最后把给老外发的邀请函草稿贴出来，供大家参考：
