作为学者的他,儒雅、内敛、朴实无华;身居高位的他,深沉、智慧、字字珠玑。仿佛是在昨天,经历艰难,享受欢乐,无怨无悔,只因为对祖国母亲的依恋。几十个春秋岁月,他的忠贞信念从未改变。值此张院士八十寿辰之际,我们衷心地祝愿他,身体健康,幸福快乐。 As a scholar, he is refined, introverted, unpretentious; he is a tall, deep, intelligent, well-respected person. As if yesterday, experienced hardships, enjoyment of joy, no regrets, just because of attachment to motherland. Dozens of years of age, his faith has never changed faithful. On the occasion of the 80th birthday of this academician, we sincerely wish him good health and happiness.
