1.30在sustainability投了个文章，1.31under reviewing，今天给我发个邮件内容如下：
Please let us know if all the figures and tables in your manuscript have
been submitted for publication for the first time or can be used without
any copyright constraints. If this is not the case, please provide
copyright permissions where they are necessary. If you adapt or use only
a part of a figure or table published in a non-open access resource,
copyright permission is still needed. Copyright permissions can usually
be obtained via an online form or by e-mailing the copyright holder, and
it is the authors’ responsibility to obtain them.
大意是问我文章里的图和表是不是首次发表，是否涉及版权争端。
有人遇到这种情况没？我只需要回复邮件就行吗，需不需要在提交系统里确认什么？
