我第一次为 Springer 期刊准备文章。我很久以前就见过将其放入论文中的公式。如何使用 Springer 期刊的“svjour3”包将其写入双栏文章中的一栏中。同样，如何在同一篇文章中添加“命名法”。
对于 LaTex 文件，请参见下文：

The functions $F_1$, $F_2$ and $F_3$ are given below
\begin{equation}
F(x_{1}, y_{1}, z_{1})=\frac{l x_{0}(1+b+c\sigma)}{\omega(1+b)} P(x_{1}, y_{1}, z_{1})+l\frac{\omega^{2}+b(1+b+c\sigma)}{x_{0}\omega(1+b)^{2}}Q(x_{1},y_{1},z_{1})+\frac{l x_{0}}{\sigma} R(x_{1}, y_{1}, z_{1})

答案1
我没有看到摆脱两列布局的方法。相反，我建议使用包multline中的环境amsmath。下面的示例使用了一些\hspace和\hfill来调整随后多行的水平对齐。
\RequirePackage{fix-cm}
\documentclass[twocolumn]{svjour3}
\usepackage{calc}
\newlength{\firsttermlength}
\providecommand{\firstterm}{}
\newcommand{\ftspace}{\hspace{\firsttermlength}}
\newcommand{\setfirstterm}[1]{%
\renewcommand{\firstterm}{\ensuremath{#1}}%
\setlength{\firsttermlength}{\widthof{\firstterm}}}
\usepackage{amsmath}
\usepackage{lipsum}
\journalname{Springer Journal}
\begin{document}
\title{Title of the Article}
\author{Author's Name}
\institute{Author's Institute Name\\

The functions $F_1$, $F_2$ and $F_3$ are given below
%
% we declare the first term ahead of the multline environment, so that
% its width becomes available for aligning the second and third row.
% the term itself is available in \firstterm, so that it does not need
% to be repeated.
%
\setfirstterm{F(x_{1}, y_{1}, z_{1})}
%
\begin{multline}
\firstterm\:=\:\frac{l x_{0}(1+b+c\sigma)}{\omega(1+b)} P(x_{1}, y_{1}, z_{1}) \\[1em]
\ftspace\: +\:l\frac{\omega^{2}+b(1+b+c\sigma)}{x_{0}\omega(1+b)^{2}}Q(x_{1},y_{1},z_{1}) \\[1em]
