我在用这个模板使用 创建海报beamerposter。我正在尝试创建一张双栏海报，其中参考资料占据末尾的两栏。
以下是我的尝试。基本上，我所做的是首先创建一张巨大的单列宽海报，将其分成两部分，然后在最后重新合并。但是，我不明白为什么它不起作用：
\documentclass[final, 20pt]{beamer}
\usepackage[size=a0, scale=1.5]{beamerposter} % Use the beamerposter package for laying out the poster
\usepackage{array, multirow, hhline}
\usetheme{confposter} % Use the confposter theme supplied with this template
\setbeamercolor{block title}{fg=ngreen,bg=white} % Colors of the block titles
\setbeamercolor{block body}{fg=black,bg=white} % Colors of the body of blocks
\setbeamercolor{block alerted title}{fg=white,bg=dblue!70} % Colors of the highlighted block titles
\setbeamercolor{block alerted body}{fg=black,bg=dblue!10} % Colors of the body of highlighted blocks
% Many more colors are available for use in beamerthemeconfposter.sty
%-----------------------------------------------------------
% Define the column widths and overall poster size
% To set effective sepwid, onecolwid and twocolwid values, first choose how many columns you want and how much separation you want between columns
% In this template, the separation width chosen is 0.024 of the paper width and a 4-column layout
% onecolwid should therefore be (1-(# of columns+1)*sepwid)/# of columns e.g. (1-(4+1)*0.024)/4 = 0.22
% Set twocolwid to be (2*onecolwid)+sepwid = 0.464
% Set threecolwid to be (3*onecolwid)+2*sepwid = 0.708
\newlength{\sepwid}
\newlength{\onecolwid}
\newlength{\twocolwid}
\setlength{\paperwidth}{48in} % A0 width: 46.8in
\setlength{\paperheight}{96in} % A0 height: 33.1in
\setlength{\sepwid}{0.024\paperwidth} % Separation width (white space) between columns
\setlength{\onecolwid}{0.464\paperwidth}
\setlength{\twocolwid}{0.952\paperwidth}
\setlength{\topmargin}{-0.5in} % Reduce the top margin size

知道为什么该部分References根本没有显示吗？

我无法编译您问题中的非最小示例（错误File ended while scanning use of \@xdblarg.），而且距离最小示例太远，我不想调试，但基本上您可以关闭环境columns并继续使用正常文本。
\documentclass[final, 20pt]{beamer}
\usepackage[size=a0, scale=1.5]{beamerposter}
\usepackage{lipsum}
\setlength{\topmargin}{0.5in} % Reduce the top margin size
\setlength{\parskip}{3em}
\begin{document}
\begin{frame}[t]
\begin{columns}[onlytextwidth]
\begin{column}{.45\textwidth}
\lipsum[2]
\end{column}
\begin{column}{.45\textwidth}
\lipsum[2]
\end{column}
\end{columns}
\lipsum[2]
\end{frame}
\end{document}
