latex \cite, \citet, \citep

两个基本的cite命令是：citet 和 citep，区别如下：

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
