【摘要】 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。更多还原

【Abstract】 This paper presents the precise expression of definite number ranges in scientific papers based on the concept and expression of the finite interval.After theoretical and practical corroborations,we hold that,for expression of definite number ranges,the finite interval expression is more concise,precise and strict compared with the conventional limit value expression.This will provide new insights into the revision of GB/T1250-1989.更多还原
