初次听说徐光宪院士的大名,还是在刚上北大的时候,那时化学系的这几位学界泰斗叫我们这些后辈高山仰止,只是一直无缘拜见。后来毕业后留在系里,有幸与徐先生工作于同一教研室,才和他有了近距离的接触。对他了解越多,越是有“夫子步亦步,夫子趋亦趋,夫子驰亦驰,夫子奔逸绝尘,而回瞠若乎后矣”之感。故作此文,以抒胸臆。 For the first time I heard Xu Guangxian academician’s name, or just on the Peking University, when the chemistry department of these academic leaders called us these younger generations alpine Yangzhi, but has been missed. Later graduated in the department, fortunate enough to work with Mr. Xu in the same teaching room, and he had close contact. The more you know about him, the more you have the feeling of “Master walking step by step, Master tending, Master Chi Chi, Master Ben Yat run away, And back to Ruo if later men”. So for this article, to express my feelings.
