1.数值范围号的使用应统一,一般使用浪纹连接号“~”。例如:5至10可写成5~10;但5万至10万应写成5万~10万,不能写成5~10万。2.幂次相同的参数范围:前一个参数的幂次不能省略。例如:3×109~5×109不能写成3~5×109,但可以写成(3~5)×109。3.百分数范围:前一个参数的百分号不能省略。例如:20%~30%不能写成20~30%。4.单位相同的参数范围,只需写出后一个参数的
1. The use of numerical range of numbers should be uniform, the general use of corrugated connection number “~ ”. For example: 5 to 10 can be written as 5 to 10; but 50,000 to 100,000 should be written 50,000 to 100,000, can not be written 5 to 10 million. 2. The same order of the power of the parameters: the power of a parameter can not be omitted. For example: 3 × 109 ~ 5 × 109 can not be written as 3 ~ 5 × 109, but can be written as (3 ~ 5) × 109.3% Range: The percentage of the previous parameter can not be omitted. For example: 20% ~ 30% can not write 20 ~ 30%. 4. The unit of the same parameter range, just write the last parameter
