Dear Sir or Madam:
As a chemistry professor with the Graduate School of the Chinese Academy of Sciences, I have the honor to recommend Mr. Hu Yiangping to study chemistry at your university.
A postgraduate educational institution, the CAS Graduate School is the school where all postgraduates from all research institutes within the CAS system must undergo basic course studies for the first year. It was in this capacity that Mr. Hu came to the school and became my student. In my contact with him for one year or more, I was deeply impressed by Mr. Hus performance. During the one-year period, I taught him three basic professional courses, namely, Quantum Chemistry, Quantum Chemical Calculation, and Experiment in HPLC. The first two courses were very difficult theoretical courses for many students but Mr. Hu showed very solid theoretical basis in both of them. This, plus his strong thirst for knowledge and hardworking spirit, left a very deep impression on me. Finally he got more than 90 marks for both. But examinations were not his ultimate goal. It was strong desire for knowledge that motivated his hard study. When the study of the subjects was over, Mr. Hu would fetch me on vacations to discuss about Quantum Chemistry. During the discussions I got to further know his unique and deep understanding on many pioneering issues in the field. Meanwhile I got to know his desire for chemical research as his future career. It was really very pleasing for me that such an excellent student like him made such a professional choice.
Mr. Hu has not only achieved prominent results in theoretical studies, but has made extraordinary performance in experiment lessons. For example the Experiment in HPLC lesson I taught was one of the important experiment lessons consuming many class hours. It called for the operation of many instruments, such as HPLC, IR and UV. In this lesson Mr. Hu was displayed conscientiousness and carefulness He was good at making observations and finding problems from phenomena. Such a thinking quality made his experiment reports wonderful or even of certain scientific value.
Although I have had contacts with Mr. Hu for only one year, I feel that Mr. Hu is a student of great potentiality academically. Learning that he is planning to further his studies in the United States today, I am very pleased to recommend him to your university and sincerely hope that you will accept his application.

To Whom this May Concern:
I am ex-director of the Chengdu Organic Chemistry Research Institute of CAS. I am heartily recommending a very good graduate from our institute Mr. Hu Yiangping to your chemistry department.
Mr. Hu came to our institute for Master Degree solid acid studies in September 1998. This was a very difficult subject. Plus the limitation of the institute apparatuses and funding Mr. Hu met with setbacks in his work. But he showed strong scientific research initiative soon afterwards. As the subject group was set up very late, there was a sharp shortage of instruments and apparatuses. Thereupon, Mr. Hu used his own hands to make some makeshift instruments, which eventually helped him in setting up a laboratory successfully.
Later he relied on the limited experiment conditions to carry out a series of meritorious research work programs. For example, he managed to synthesize a kind of solid acid called SO42-/ZrO2-SiO2-T2O2-SiO2 and applied it to catalyze styrene selective oxidation reaction and found it of higher catalyzing activity and selectivity. Again for example he suggested there might be a coordinated effect between HZSM-5 and dense sulfur acid, which might catalyze coupling reactions with high efficiency and selectivity, thus lessening the dosage of dense sulfur acid in reactions. Not only so, he has quite wide interest. For example he suggested a new method of measuring the mercury and arsenic in biological and pharmaceutical samples with micro dissolution --- atom fluorescent spectrum. He had many other similar research findings. Finally he published six research theses in domestic magazines and applied for two invention patents. He also published four articles at national and international academic conferences. Achieving so many attainments within such a short span of time was quite a remarkable success for a Master Degree student, indeed.
Besides, Mr. Hus tenacity in scientific research is also noteworthy. For example it was necessary to make a 500-hour catalyst life perspective experiment in the final stage of subject research. To guarantee the smooth completion, Mr. Hu completed the difficult experiment by way of stubborn stamina and obtained satisfactory results. We may well say that it was this spirit and talent that made Mr. Hu so successful in his scientific research.
Thanks to his excellent performance during the Master Degree studies period, Mr. Hu earned the Presidents Scholarship for Excellent Research Career, CAS Chengdu Branch. With this he completed his studies in our institute with full success.
A review of Mr. Hus scientific research process shows that he is the pride of our institute. Meanwhile I wish Mr. Hu would become the pride of your university as well. Finally I would like once again to recommend him without any reservation.
Yours Sincerely
