图上作业法是由羣众中来的一个优秀的数学方法,数学通报1958年11期已作了介紹,經过了理論上的总結提高后,目前它已經在很多有关物資調运的部門中得到推广,而且国家經委已批轉了中国科学院数学研究所关于推广图上作业法的建議,即又回到羣众中去了,它的誕生及成长过程是这样的丰富多彩,激动人心,因而不能让它默默无聞,必須公之众目,在中国数学会北京分会举办的一次报告会上,我介紹了这一工作,并談了自己的一点体会,同志們认为还不无有益之处,因此我重新把它整理了一下,提出来和大家作进一步的研討。意見很不成熟,希望同志們多加指正,为了避免重复,关于图上作业法的方法和理論証明,請看1958年11期数学通报,这里就不重述了。 (一) “实践-理論-实践”的公式在数学中的应用为什么我从图上作业法談起呢?因为它具有下述的三方面特点:
The operation method on the map is an excellent mathematical method developed by the masses. The mathematics bulletin has been introduced in the 11th period of 1958. After a theoretical summary, it is now in many departments involved in material transfer. China has been promoted, and the State Economic Commission has approved the proposal of the Institute of Mathematics of the Chinese Academy of Sciences to promote the map-based operating method, that is, it has returned to the masses. Its birth and growth process is so colorful and exciting. Therefore, we must not let it be obscured and it must be public. At a report meeting organized by the Beijing Branch of the Chinese Mathematical Society, I introduced this work and talked about my own experience. Comrades believe that it is not without its usefulness. At the same time, I reorganized it and put forward for further discussion with you. The views are very immature. I hope that the comrades will correct them more. To avoid duplication, the methods and proofs of the theory on the map are shown in the 11th issue of the 1958 Bulletin. This is not repeated here. (1) The application of the “practice-theory-practice” formula in mathematics Why do I talk about it from the graph-work method? Because it has the following three characteristics:
