针对作者来稿在数值的表示中存在的问题,现就论文中数值的范围和公差的表示法简介于下:1.数值的范围:用波浪纹号“～”作连接表示。①带万或亿万的数值中的万或亿不能省略,如2万～4万。②幂次相同的数值的幂次都要写出,如:3×104～6×104可写成(3～6)×104,但不能写成3～6×104。③百分数范围中每个百分数后面的“%”都要写出,如:20%～30%不能写成20～30。④单位相同的量值可
In view of the author’s contribution in the numerical representation of the existing problems, now on the papers numerical range and tolerance representation is described below: 1. Numerical range: with the wave pattern “~ ” for the connection. ① million or billion with thousands or millions of values can not be omitted, such as 20,000 to 40,000. ② The power of the same degree of power should be written out, such as: 3 × 104 ~ 6 × 104 can be written as (3 ~ 6) × 104, but can not write 3 ~ 6 × 104. ③ Percentage range of the back of each percent “” must write, such as: 20% ~ 30% can not be written as 20 ~ 30. ④ the same amount of units can be
