如何消除横向页面前的空白？如下所述：删除横向之前的空白，\afterpage 对我来说不起作用。请参阅下面的示例。

刚刚发现，使用该代码可以正常工作。因此，它一定是导致问题的软件包之一。
\documentclass[a4paper, 12pt]{article}
\DeclareUnicodeCharacter{FB01}{fi}
\DeclareUnicodeCharacter{FB02}{fl}
%\usepackage[space]{grffile}
\usepackage{apacite}
\usepackage{lipsum}
\usepackage{makecell}
\usepackage{afterpage}
\usepackage{lscape}
\begin{document}
\section{Empirical results}
\label{sec2:results}
\lipsum[3-5]
\afterpage{
\begin{landscape}
Test
\end{landscape}
}
\lipsum[3-5]
\end{document}
分页符来自 \newgeometry，它现在可以工作了：
