Latex：引用两个在同一位置具有相同名字作者的引用时如何避免省略作者的名字

Question

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

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

但是我想要的样式是：

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

如ref.bib中所示，两位作者的姓名并不完全相同。但是默认情况下，第二个参考文献的作者被省略。

我的book.tex示例

\documentclass[a4paper,12pt]{article}
\usepackage{amsmath}
\usepackage{graphicx}
\usepackage{float}
\usepackage[semicolon,square,sort&compress,sectionbib]{natbib}
\renewcommand\theequation{\arabic{section}-\arabic{equation}}
\renewcommand\thefigure{\arabic{section}-\arabic{figure}}
\title{In nature}
\author{Null}
\date{}

\begin{document}
In \citep{liu2007cast,liu2011shadow}, the lower intensity rule is used as a preclassifier in their method. 
\bibliographystyle{abbrvnat}
\bibliography{ref}
\end{document}
