為什麼Zotero用APA樣式插入引用之後，日期後面會出現a或b？ / Why Does a Letter Like ‘a’ or ‘b’ Appear After the Date When Inserts a Citation via Zotero in APA Style?

根據APA樣式的規範，如果出現同樣作者、同樣日期(主要是年份)的時候，文內引用需要加上a、b來區別。Zotero可能只是遵循了這條規則。

According to APA style guidelines, if there are publications with the same author and the same date (primarily the year), in-text citations need to include letters like 'a', 'b' to distinguish them. Zotero might just be following this rule.
