　　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 fect between HZSM-5 and dense sulfur acid, which might catalyze coupling reactions with high ficiency 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. Hu&aposs 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 President&aposs Scholarship for Excellent Research Career, CAS Chengdu Branch. With this he completed his studies in our institute with full success.

　　A review of Mr. Hu&aposs 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
