Latex：如何避免在同一 position 中引用同名作者的两个参考文献时省略作者姓名

Question

我通过\citep{liu2007cast,liu2011shadow}命令引用了 2 个引用，它的样式（编译后）是：

In [Liu et al., 2011, 2007], the lower intensity rule is used as a preclassier in their method.

但我想要的风格是：

In [Liu et al. 2011, Liu et al. 2007], the lower intensity rule is used as a preclassier in their method.

如 ref.bib 所示，两位作者的姓名并不完全相同。 但默认情况下省略了第二个参考的作者。
