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
citetext{priv. comm.} --> (priv. comm.)
