摘 要: 区间数运算的提出初衷是为了提高计算结果的可靠性,随后人们很快发现区间数算法可以有更广泛的应用。但同时也发现当两个区间数相等时,在标准运算下他们的差运算与商运算与普通实数的运算相差甚远。为此,本文提出了区间数的限定运算,并给出了四种运算法则,探讨了该运算与标准运算之间的关系,同时也给出了一些良好的性质。
关 键 词: 基础数学;区间数;标准运算;限定运算

Abstract: The interval number arithmetic proposes that original intention is for the dependability of improving the result of calculation, People find the interval arithmetic is more extensive application . But at the same time that when two interval numbers are equal to, their addition operation and devision operation are difference from real number. For this reason, this paper puts forward a kind of new interval number arithmetic, and gives four kinds of operation rules , discusses the relation with standard interval number arithmetic and gives some satisfied characters.
Key words: basic math; interval number; standard arithmetic; constraint arithmetic
