手稿指导：https://www.springer.com/journal/10951/submission-guidelines?IFA#Instructions for Authors_Manuscript Submission 在指导里下载出来的模板是： ```tex \RequirePackage{fix-cm} \documentclass[twocolumn]{svjour3} % twocolumn % \smartqed % flush right qed marks, e.g. at end of proof \begin{document} \title{Insert your title here } \subtitle{Do you have a subtitle?\\ If so, write it here} \author{First Author \and Second Author %etc. } \institute{F. Author \at first address \\ Tel.: +123-45-678910\\ Fax: +123-45-678910\\ \email{fauthor@example.com} % \\ % \emph{Present address:} of F. Author % if needed \and S. Author \at second address } \date{Received: date / Accepted: date} % The correct dates will be entered by the editor \maketitle \end{document} ``` 编译后这风格出来的是：  但是我看期刊正式发布的是这个风格：  存在一个疑问:我该以哪个风格呢， 1按照指导里的只能列一个邮箱，\email用了多个编译报错，不知道是不是我用法不对 2如果按照出版期刊的话，我写的代码，有些格式不太对： ```tex \RequirePackage{fix-cm} \documentclass[twocolumn]{svjour3} % twocolumn \usepackage[misc]{ifsym} % \smartqed % flush right qed marks, e.g. at end of proof \begin{document} \title{Insert your title here } \subtitle{Do you have a subtitle?\\ If so, write it here} \author{A\textsuperscript{1} \and B\textsuperscript{1} \and C\textsuperscript{2} \and D\textsuperscript{1} \and E\textsuperscript{1} %etc. } \institute{ \textsuperscript{1} address1 \\ \and \textsuperscript{2} address2 \\ %Tel.: +123-45-678910\\ % Fax: +123-45-678910\\ \Letter email auther \\ email \\ A \\ Aemail\\ B\\ Bemail\\ C \\ Cemail \\ } \date{Received: date / Accepted: date} % The correct dates will be entered by the editor \maketitle \end{document} % end of file template.tex ``` 出来的风格：  我用风格1该怎么写多个邮箱呢，如果风格2的话怎么控制样式更贴合呢
