在初步阅读了《全国VE电视教材》(以下简称《教材》)并参加对其研讨之后,觉得《教材》对于成本功能的关系,作了比较科学的表述,提出了“功能与成本之间的动态相关原理”。 一、成本水平具有不确定性和变动性。 1.科技水平不同引起的差异。产品生产采用新原理,新结构,新材料,新工艺等的程度,内容不同,其成本有异。 After a preliminary reading of the “National VE Television Teaching Materials” (hereinafter referred to as “Teaching Materials”) and its discussion with the government, I think that “teaching materials” make a comparatively scientific statement about the relationship between cost functions and put forward the concept of “between function and cost Dynamic Related Principle. ” First, the cost level is uncertain and variable. 1. Differences caused by different levels of science and technology. The production of new principles, new structure, new materials, new technology, the degree of different content, the cost is different.
