与 &inproceedings 不同，@article 引用后有一个额外的空格。我想消除额外的空格。当我使用 DOI 链接时也有一个额外的空格。我该如何删除这些额外的空格？

%This is the code I have used in the main.tex for

\makeatother
%I have also tried to reduce the spacing in
%sn- jnl.cls file by setting 0em in setlength. This
%helped in reducing the space in inproceeding
%journals but not for articles. There are
%still extra spaces after the article references.

我正在尝试获取如下所示的参考列表。
（注：我使用的是 overleaf Latex）
我一直在努力删除空格。有人能帮我解决这个问题吗？我正试图将我的论文提交给 Springer 期刊之一。
