Latex 中cite的使用
（一）、设置上标显示的命令
可以在引言区增加类似如下的重定义命令：
\newcommand{\upcitep}[1]{\textsuperscript{\textsuperscript{\citep{#1}}}} % 设置上标显示参考文献编号的命令
然后再在正文中使用新定义的命令:
abc \upcitep{Label} ---> abc^[2] %% ^表示 后面是上标形式
(二) 、两个基本的cite命令是：\citet 和 \citep，区别如下：（注：需要使用包\usepackage{natbib}）
\citet{jon90} --> Jones et al. (1990)
\citet[chap. 2]{jon90} --> Jones et al. (1990, chap. 2)
\citep{jon90} --> (Jones et al., 1990)
\citep[chap. 2]{jon90} --> (Jones et al., 1990, chap. 2)
\citep[see][]{jon90} --> (see Jones et al., 1990)
\citep[see][chap. 2]{jon90} --> (see Jones et al., 1990, chap. 2)
\citet*{jon90} --> Jones, Baker, and Williams (1990)
\citep*{jon90} --> (Jones, Baker, and Williams, 1990)
此外还有诸如只引作者名字的\citeauthor，\citeyear
| \citeauthor{jon90} | --> | Jones et al. |
| \citeauthor*{jon90} | --> | Jones, Baker, and Williams |
| \citeyear{jon90} | --> | 1990 |
| \citeyearpar{jon90} | --> | (1990) |
多个参考文献引用：
| \citet{jon90,jam91} | --> | Jones et al. (1990); James et al. (1991) |
| \citep{jon90,jam91} | --> | (Jones et al., 1990; James et al. 1991) |
| \citep{jon90,jon91} | --> | (Jones et al., 1990, 1991) |
| \citep{jon90a,jon90b} | --> | (Jones et al., 1990a,b) |
不同的latex编译环境下有不同额格式，如：
| \citet{jon90} | --> | Jones et al. [21] |
| \citet[chap. 2]{jon90} | --> | Jones et al. [21, chap. 2] |
| \citep{jon90} | --> | [21] |
| \citep[chap. 2]{jon90} | --> | [21, chap. 2] |
| \citep[see][]{jon90} | --> | [see 21] |
| \citep[see][chap. 2]{jon90} | --> | [see 21, chap. 2] |
| \citep{jon90a,jon90b} | --> | [21, 32] |
此外，还有以上两个命令对应的去掉括号的命令：
| \citealt{jon90} | --> | Jones et al. 1990 |
| \citealt*{jon90} | --> | Jones, Baker, and Williams 1990 |
| \citealp{jon90} | --> | Jones et al., 1990 |
| \citealp*{jon90} | --> | Jones, Baker, and Williams, 1990 |
| \citealp{jon90,jam91} | --> | Jones et al., 1990; James et al., 1991 |
| \citealp[pg. 32]{jon90} | --> | Jones et al., 1990, pg. 32 |
| \citetext{priv. comm.} | --> | (priv. comm.) |
