以往的科学技术实践知识,告诉了我们:一切客观事物均可分为实体和边缘两个组成部分。在认识世界和改造世界过程中,起决定作用的区域,在于事物实体的内部,但是起主导作用的部位,大都分布于边缘区域。人们要认识和变革事物,较为合理的办法,就是先从边缘分析入手,选择出最合理的突破口,从而作出节能、省工、省料的加工方案。本文试图引用有关事例,阐明这一朴素的概念。 Past scientific and technological practical knowledge tells us that all objective things can be divided into two parts: the entity and the periphery. The regions that play a decisive role in understanding the world and transforming the world lie in the interior of the entity of things, but the dominant parts are mostly located in the marginal areas. People want to know and change things, a more reasonable approach is to start with the edge analysis, choose the most reasonable breakthrough in order to make energy-saving, labor-saving, material-saving processing programs. This article attempts to cite relevant examples to clarify this simple concept.
