运用有限区间的基本概念和表达方式,对科技论文中确定数值范围进行准确表述。通过理论与实例印证,认为对于确定数值范围的表达,与传统的极限数值表达方式相比,有限区间表达方式具有简洁、准确、严谨等优势,这为GB/T 1250—1989《极限数值的表示方法和判定方法》的修订提供了新的思路。
Using the basic concepts and expressions of finite interval, we accurately describe the range of numerical values in scientific papers. By theoretical and practical examples, it is considered that the finite interval expression method has the advantages of conciseness, accuracy and rigor as compared with the traditional limit numerical expression for determining the expression of numerical range. This is the expression of the limit value of GB / T 1250-1989 Methods and Judgments "provides a new way of thinking.
