本文英文内容摘自

"Anne M. Coghill, Lorrin R. Garson. The ACS Style Guide: Effective Communication of Scientific Information, American Chemical Society: Washington, DC, 2006"

第二部分(Part 2. Style Guidelines

11章(11. Numbers, Mathematics, and Units of Measure

214–215

 

Spacing

空格

 

Ø  Leave   a space before and after functions set in roman type, unless the argument is   enclosed in parentheses, brackets, or braces.

Ø  除非参数包含在圆括号、方括号或大括号中,否则在以罗马字体的函数前后留空格。

 

log 2

–log   x

4 sin   θ

tan2   y

exp(–x)

cosh(βe0φ)

4   tan(2y)

erfc(y)

 

Ø  Leave   a space before and after mathematical operators that function as verbs or   conjunctions; that is, they have numbers on both sides or a symbol for a   variable on one side and a number on the other.

Ø  在充当动词或连词的数学运算符前后留空格;也就是说,它们的两边都有数字,或者一边是变量的符号,另一边是数字。

 

20 ±   2%

3.24   ± 0.01

4 × 5   cm

8 ×   10–4

k ≥ 420 s–1

p <   0.01

Tg =   176 °C

n = 25

1   in. = 2.54 cm

 

例外1

Leave   no space around mathematical operators in subscripts and superscripts.

上标和下标中的数学运算符前后不留空格。

 

1:ΔHn–1

2Eλ>353

3M(x+y)+

 

例外2

Leave   no space around a slash (a/b), a ratio colon (1:10), or a centered dot (PV).

斜杠(a/b)、比率冒号(1:10)或中心点(PM·V)前后不留空格。

 

Ø  Leave   no space between simple variables being multiplied: xy. Do not use a centered dot (·) or the times sign (×) with   single-letter scalar variables.

Ø  要相乘的简单变量之间不留空格:xy。切勿在单字母标量变量中使用中心点(·)或乘号(×)。

 

Ø  In   multiplication involving the two-letter symbols for transport properties, use   a space, enclose them in parentheses, or use the times sign. When   superscripts or subscripts are present, the symbols can be closed up.

Ø  在涉及传输属性的双字母符号的乘法中,使用空格、将它们括在括号中或使用乘号。当存在上标或下标时,符号可以闭合。

 

1Re Nu

2(Re)(Nu)

3Re × Nu

4RexNuy

 

Ø  Use a   space for simple multiplication of functions of the type f(x) (one-dimensional)   or g(y, z)   (multidimensional). Close up multipliers to such functions where applicable.   You may also use additional enclosing marks instead of spaces.

Ø  使用空格对f(x)(一维)或g(y, z)(多维)类型的函数进行简单乘法。在适用的情况下,闭合此类函数的乘数。亦可使用附加的封闭标记代替空格。

 

1W = 2f(x) g(y, z)(空格)

2W = 2[f(x)][g(y, z)](闭合标号——方括号)

 

Ø  When   mathematical symbols are used as adjectives, that is, with one number that is   not part of a mathematical operation, do not leave a space between the symbol   and the number.

Ø  当数学符号用作形容词时,也就是说,使用一个不属于数学运算的数字时,不要在符号和数字之间留空格。

 

–12   °C

25 g   (±1%)

at   400× magnification

The   level can vary from –15 to +25 m.

a   conversion of >50%

a   probability of <0.01
