Parentheses
括號(hào)
?
Parenthetical ? expressions contain information that is subsidiary to the point of the ? sentence. The sentence does not depend on the information within the parentheses.
括號(hào)表達(dá)包含輔助句子要點(diǎn)的信息。這個(gè)句子不依賴于括號(hào)內(nèi)的信息。
?
?? Use ? parentheses for parenthetical expressions that clarify, identify, or ? illustrate and that direct the reader.
?? 使用括號(hào)作為插入語，以澄清、識(shí)別或說明并引導(dǎo)讀者。
?
例1：The total amount (10 mg) was recovered by modification of the procedure.
例2：The final step (washing) also was performed under a hood.
例3：The curve (Figure 2) obeys the Beer–Lambert law.
例4：The results (Table 1) were consistently positive.
例5：Only 15 samples (or 20%) were analyzed.
?
?? Punctuate ? after, not before, parenthetical expressions.
?? 在插入語之后而不是之前加標(biāo)點(diǎn)符號(hào)。
?
錯(cuò)誤示例1：Compound 1, (7 mg) obtained by typical workup methods, was used without further purification.
正確示例1：Compound 1 (7 mg), obtained by typical workup methods, was used without further purification.
?
?? If a ? parenthetical sentence is within another sentence, do not use a final period ? within the closing parenthesis, and do not start the parenthetical sentence ? with a capital letter.
?? 若一個(gè)帶括號(hào)的句子在另一個(gè)句子中，不要在右括號(hào)中使用終止句點(diǎn)，也不要用大寫字母開頭。
?
例1：Our results (the spectra are shown in Figure 5) justified our conclusions.
例2：Our results justified our conclusions (the spectra are shown in Figure 5).
?
?? If a ? parenthetical sentence is not within another sentence, use a final period ? inside the closing parenthesis, and start the parenthetical sentence with a ? capital letter.
?? 若一個(gè)帶括號(hào)的句子不在另一個(gè)句子中，請(qǐng)?jiān)谟依ㄌ?hào)內(nèi)使用終止句點(diǎn)，并用大寫字母開頭。
?
例1：A mechanism involving loss of a CH radical followed by rearrangement was proposed. (The reactions are shown in Scheme 1.)
?
?? Use parentheses ? to enclose numerals in a list. Always use parentheses in pairs, not singly.
?? 在列表中用括號(hào)括起數(shù)字?？偸浅蓪?duì)使用括號(hào)，而不是單個(gè)使用。

?? 在敘述性文本中引用參考文獻(xiàn)序號(hào)時(shí)，不要使用括號(hào)。在這種情況下，參考文獻(xiàn)序號(hào)是句子的要點(diǎn)，而不是輔助信息，因此不要括起來。
?
錯(cuò)誤示例：in ref (12), in (12)
正確示例：in ref 12
?
?? Use ? parentheses in mathematical expressions as discussed in Chapter 11 and in ? chemical nomenclature and notation as discussed in Chapters 12 and 13.
?? 在第11章討論的數(shù)學(xué)表達(dá)式中使用括號(hào)，在第12章和第13章討論的化學(xué)命名法和符號(hào)中使用括號(hào)。
