【摘要】：昂萨格影响了杨振宁求解出伊辛模型的自发磁化强度、证明单位圆定理、提出非对角长程有序的概念和杨-巴克斯特方程。透视这一历程,启示有二:第一,科研选题不应轻视其小,只要与学科的基本现象或问题、基本定律相关,小题目的解决可能引发系列问题,进而导致大的进步甚至革命性突破。第二,具备深刻的洞察力才能找到好的问题,而洞察力的培养离不开理论积累与实践工作。理论积累意味着深厚的理论功底和宽宏的理论视野;演算、推导是理论性学科不可或缺的实践性工作。
[Abstract]:Unsager influenced Yang Zhenning to solve the spontaneous magnetization of Ising model, proved the theorem of unit circle, and put forward the concept of non-diagonal long term order and Yang-Baxter equation. There are two revelations from the perspective of this process: first, scientific research topics should not be lightly selected, as long as they are related to the basic phenomena or problems of the subject, the basic laws, and the solution of small problems may lead to a series of problems. Thus leading to great progress and even revolutionary breakthroughs. Second, with deep insight, we can find a good problem, and the cultivation of insight can not be separated from theoretical accumulation and practical work. Theoretical accumulation means a profound theoretical foundation and a broad theoretical field of vision; calculus and derivation are indispensable practical work for theoretical disciplines.
