彭桓武院士是我们的入门老师,今年10月6日他八十岁了。岁月如梭,回忆往事犹历历在目。 1956年我们大学毕业时,彭先生和黄祖洽先生刚从苏联学习反应堆理论归来。当时国内还没有人搞反应堆理论,苏联援建的重水反应堆正在建设,计划于1958年开堆做临界实验。为了培养一批反应堆理论工作者,从北大技术物理系挑选了十来个人,又从其它院校挑选了数学、工程方面专业的十来个人。头一年由彭先生亲自讲反应堆理论课,接着黄先生指导我们做反应堆的物理计算,与此同时,彭先生主持每周一次的seminar(学术讨论班),由我们轮流报告世界各国实验和动力反应堆的研究发展情况。这样的seminar即使在1957年“反右”运动中也雷打不动。在那段时间里我们与彭先生接触较多,他的耳提面命、谆谆教导使我们终生难忘。 一、关于对基础理论与应用理论研究的看法 在当时的青年学生中普遍存在一种“唯有基础理论高”而轻视应用理论的思想倾向。在我们这群人中就有人说:“造十个反应堆还不
Academician Peng Huanwu is our entry-level teacher. He was eighty years old on October 6 this year. Time flies, memories of the past is still in sight. When our university graduated in 1956, Mr. Pang and Mr. Huang Zuchao just returned from studying Soviet reactor theory. At that time, no one in the country was engaged in the theory of reactors. The heavy water reactor aided by the Soviet Union was under construction and plans to open a critical heap experiment in 1958. In order to train a batch of reactor theoretical workers, a dozen individuals were selected from Peking University’s Department of Technical Physics and ten majors of math and engineering from other institutions. In the first year Mr. Peng personally talked about the reactor theory and then Mr. Huang instructed us to do the physical calculation of the reactor. Meanwhile, Mr. Pang presided over the weekly seminar (academic discussion), which we took turns to report the experiments and motivation of various countries in the world Reactor research and development. Such a seminar did not move even in the 1957 “anti-rightist” movement. During that time, we had more contact with Mr. Pang. His advice gave us unforgettable memories. First, on the basic theory and applied theory research view At the time of the prevalence of a young student, “only the basic theory of high” and despise the application of the ideological tendencies. Someone in our group said: "It is not yet possible to build ten reactors
