The difference between a backslash and a forward slash might not seem much. But these symbols aren’t interchangeable, and only one is technically used as punctuation.
反斜杠(\)和正斜杠(/)看起來似乎差別不大。但這些符号是不可互換的，嚴格來說這兩者隻有一種能被當作标點符号用在書面表達上。
01
The Forward Slash ( / )
正斜杠
The forward slash is a common punctuation mark, especially in less formal writing. It is usually used in place of ‘or’ when presenting a series of options or alternatives:
正斜杠是一種常見的标點符号，特别是在不太正式的寫作中。它通常被用來代替“或者”或當提出一系列的選項時使用。
“
Every student must do his/her reading before class.
每個學生必須在課前完成他或她的閱讀任務。
Using a slash between ‘his’ and ‘her’ here is the same as saying ‘his or her’. Generally, though, you would not use a forward slash like this in formal writing, where writing ‘or’ would be standard.
在“his”和“her”之間使用斜杠相當于“他”或“她”。一般來說，在正式寫作中，你不會使用像這樣的斜杠，而應該用單詞or。
The forward slash has other uses, too, including the following:
正斜杠還有其他用途，包括以下内容：
1️⃣Writing fractions or as a division sign (e.g. 3/5 = three fifths)
書寫分數或者作為除号(比方說3/5就是五分之三)
2️⃣Writing the date (e.g. 21/04/1986 = 21 April 1986)
書寫日期時(比方說21/04/1986就是1986年4月21日)
3️⃣To mean ‘per’ in a measurement (e.g. 10 m/s = ten metres per second)
在機關裡表達“每”(比方說10 m/s表示每秒十米)
4️⃣In certain abbreviations (e.g. c/o = care of, n/a = not applicable)
在某些縮寫表達裡(比方說c/o就是在乎，n/a就是不适用)
5️⃣To separate lines of poetry when written on a single line (e.g. And both that morning equally lay/In leaves no step had trodden black)
把寫在一行上的詩分開，作用相當于回車
6️⃣Website URLs (e.g. https://xxxxx.com.au/)
書寫網址時會用到
02
The Backslash ( \ )
反斜線符号
The backslash is a ‘typographical mark’ (i.e. something you can type on a computer). However, it is not a punctuation mark and you will only usually see it in computing. Specifically, the backslash is primarily used in programming languages and file directories on Windows computers. So unless you are writing about computers, you should not need to use this symbol very often.
反斜杠是一個排印标記(也就是說，你可以在電腦上輸入的東西)。然而，它不是一個标點符号，你通常隻會在計算中看到它。具體來說，反斜杠主要用于程式設計語言和Windows計算機上的檔案目錄。是以，除非你寫的是關于計算機的文章，否則你是不應該經常使用這個符号。
也就是說反斜杠“\”是電腦出現了之後為了表示程式設計裡的特殊含義才發明的專用标點。除了程式設計領域外，任何地方你都不應該有使用反斜杠的時候，請永遠使用正斜杠“/”。
