您能告訴我另一種在頁面底部放置一行文字的解決方案嗎？

Question 1

可以在頁面上對文字進行絕對定位。例如，tikz 提供了執行此操作的方法。

如果最近的 LaTeX 版本正在使用，其中 Shipout-hooks 可用，您可以將程式碼新增至掛鉤shipout/foreground。

鉤子shipout/foreground指的是左上角(0,0)位於頁面左上角、單位長度為1pt的圖片環境。
（對於頁面上發生的事情，座標的 y/第二分量需要為負。最近在環境中發布的 LaTeX 版本不需要picture關心規範化\dimexpr和長度寄存器，因為它是自動完成的。）\unitlength

\documentclass[twoside]{article}

\csname @ifundefined\endcsname{pagewidth}{}{\pagewidth=\paperwidth}%
\csname @ifundefined\endcsname{pdfpagewidth}{}{\pdfpagewidth=\paperwidth}%
\csname @ifundefined\endcsname{pageheight}{}{\pageheight=\paperheight}%
\csname @ifundefined\endcsname{pdfpageheight}{}{\pdfpageheight=\paperheight}%

\usepackage{lipsum}
\title{A sample title}
\author{John Doe}

\makeatletter
\newcommand\foo[1]{#1}
\def\@maketitle{%
\newpage
% If you want this on the titlepage only, use \AddToHookNext instead of \AddToHook
\AddToHook{shipout/foreground}{%
  \put(\dimexpr 1in+\ifodd\thepage\oddsidemargin\else\evensidemargin\fi\relax,
       \foo{\dimexpr-\paperheight+.5\dimexpr\paperheight-(1in+\topmargin+\headheight+\headsep+\textheight+\footskip)+\ht\strutbox\relax\relax})%

如果使用的 LaTeX 版本不是最新的，請考慮載入該套件內幕圖片：

下面的程式碼提供了一個範例，其中命令\AddToShipOutPicture其中包的命令內幕圖片與圖片環境相結合，其中該命令\put可用於定位文字。

\documentclass[twoside]{article}
\usepackage{lipsum,eso-pic}
\title{A sample title}

\newcommand\ConvertToUnitlength[1]{%

\AddToShipoutPicture{%
  \vbox to \paperheight{%
    \hsize=\paperwidth
    %----------------------------------------------------
    %       Within the \vbox do whatever you like:
    %       e.g., use a picture-environment:
    %----------------------------------------------------
    \setlength{\unitlength}{1cm}%
    \begin{picture}(\ConvertToUnitlength{\paperwidth},
                    \ConvertToUnitlength{\paperheight})(0,0)%
      % Inside this picture 0,0 is the bottom left corner.
      % Unit is cm.
      % If you wish to use length-parameter or \dimexppr, you can use \ConvertToUnitlength.
      % With recent LaTeX \ConvertToUnitlength is not really needed, but
      % you can use it for hiding ( and ) belonging to a \dimexpr
      % from the scanning for a )-delimiter of a \put-command.
      % You can also use eso-pic's \LenToUnit for this purpose.
      % If you need to learn about length-parameters of page-layout, see the documentation of the package "layout".
      \put(\ConvertToUnitlength{\dimexpr 1in+\ifodd\thepage\oddsidemargin\else\evensidemargin\fi\relax},
