和张永刚交谈，你会体会到什么叫真诚。这位1957年出生的上海首届科技启明星、中国科学院上海冶金研究所的研究员、博士，看上去与在大街上行走的最普通的人没任何两样。我与他见面的那天，上午下过一阵雨，他足蹬一双已显阵旧的中街套鞋，这是目前许多城市年轻人不愿意穿的雨? And Zhang Yonggang talk, you will realize what is sincere. The Shanghai science and technology star, born in 1957, a researcher and doctor at the Shanghai Institute of Metallurgy, Chinese Academy of Sciences, appears to be no different from the most average person walking on the street. The day I met him, I had a shower in the morning. He was pedaling a pair of old-fashioned Street shoes. This is the rain that many young people in cities nowadays do not want to wear?
