爆炸一颗原子弹需要一公斤左右的核燃料 U~(235),在铀物质中,U~(235)只占千分之几,而铀在铀矿中仅占万分之几,也就是说至少要从几千吨铀矿中才能提炼出一公斤 U~(235)。我国试制成功的第一颗原子弹所需的 U~(235),就是在杨承宗教授领导下,完全依靠中国人自己的智慧和力量得到的。杨承宗领导的这个集体曾受到过国务院的嘉奖。他的同事,他的学生,有的成为院士,有的佩戴上共和国勋章。时至今日,90岁高龄的杨承宗还是那句老话:事情做出来就高兴,别的什么也没想。本刊推出的特别报道——《没有勋章的功臣》,只是讲述了这样一段鲜为人知的真实故事。对照故事中的主人翁,我们可以悟出怎样去做一个真正的人,应该如何做学问、如何看待名利、如何对待功劳、如何对待同志……这就是我们介绍杨承宗其人其事的初衷。
The explosion of an atomic bomb requires about one kilogram of nuclear fuel U ~ (235). Among uranium species, U ~ (235) only accounts for a few thousandths, and uranium only accounts for a few percent in uranium, which means at least One kilogram of U ~ (235) can be extracted from thousands of tons of uranium ore. The U- (235) needed for the first successful prototype atomic bomb in our country was obtained under the leadership of Professor Yang Chengzong and entirely on the wisdom and strength of the Chinese people. The collective led by Yang Chengzong has been honored by the State Council. His colleagues, his students, some become academicians, and some wear the Republic Medal. Up to now, the 90-year-old Yang Chengzong is still an old saying: Things are happy when they are made, while others think nothing else. The special issue of this magazine - “hero without a medal” just tells such a little-known real story. We can understand how to be a real person, how to learn, how to treat fame and fortune, how to treat credit, and how to treat gay people. This is the original intention of introducing Yang Chengzong’s actions to others.
