我有一篇两列文章，我想在其中制作一列摘要，当我使用时：
\documentclass[twocolumn]{svjour3}
\journalname....
\begin{document}
\title ....
\author...
\institute...
\twocolumn[
\begin{@twocolumnfalse}
\maketitle
\begin{abstract}
...
\end{abstract}
\end{@twocolumnfalse}
]
摘要变成了一栏，但是应该出现在第一页左下角的机构信息消失了，有人可以帮忙吗？
（该图是我将摘要改为单列之前第一页的显示情况，作者显示在左下方）

更新
您可以先将\documentclass[twocolumn]{svjour3}标题和摘要切换为一列，然后使用包multicol切换到原来的两列模式。
所有浮动内容都会转到下一页。
\documentclass[twocolumn]{svjour3}
\usepackage{graphicx}% added <<<
\usepackage{multicol} % added <<<
\journalname{to be decided journal}
\begin{document}
\title{Insert the title of the article here}

\begin{abstract}
As any dedicated reader can clearly see, the Ideal of practical reason
is a representation of, as far as I know, the things in themselves; as I have shown
elsewhere, the phenomena should only be used as a canon for our understanding.

\section{Introduction}
\label{intro}
Space constitutes the whole content for
our sense perceptions, and time occupies
part of the sphere of the Ideal concerning the existence of the objects in space
and time in general.
\section{Section title}
\label{sec:1}
2. Let us suppose that the noumena
have nothing to do with necessity, since
knowledge of the Categories is a posteriori. Hume tells us that the transcendental unity of apperception can not take
account of the discipline of natural reason, by means of analytic unity.

3. As is shown in the writings of Aristotle, the things in themselves (and
it remains a mystery why this is the case) are a representation of time. Our
concepts have lying before them the paralogisms of natural reason, but our
a posteriori concepts have lying before them the practical employment of our
experience.

a^2+b^2=c^2

\section{Conclusions}
Therefore, we can deduce that the objects in space and
time (and I assert, however, that this is the case) have lying before
them the objects in space and time. Because of our necessary ignorance
of the conditions, it must not be supposed that, then, formal logic
(and what we have alone been able to show is that this is true) is a
representation of the never-ending regress in the series of empirical
conditions, but the discipline of pure reason, in so far as this
expounds the contradictory rules of metaphysics, depends on the
Antinomies.
