1、词性不同
而reference不但可以作为名词使用(意思和citation类似),它还可以作为动词使用,表示查阅;参考;给(书等)附参考资料等。
2、引用内容不同
citation是指所引用的内容,可以是名言或者某本书某个研究的观点。例如:
Statistical analysis of citation number and word frequency was made on the data.
从引文数量分析中得出了最具代表性的作者及期刊。
reference是所有一切所直接引用到的有关联的信息,可以是网页,书籍,报刊,影视资料等。例如:
From there, you use the Add method,
which creates a document and returns a reference to it.
从那里,您使用Add方法,这将创建一个文档并返回一个对该文档的引用。

reference用法
当reference作为名词使用时,有以下用法:
1、作为不可数名词:提到,说到,涉及;它一般采用句式是reference to sb/sth,例如:
This code can be followed by a reference to a specific account.
这个代码后面可以跟一个对一个特定账户的引用。
2、reference作为短语使用时,常和wth搭配使用,固定搭配格式是:with reference to/in reference to,表示关于...,相当于regarding,例如:
He refused to divulge any information regarding his whereabouts.
他拒绝透露任何有关他行踪的信息。
