you had better response to the questions raised by reviewers point by point and arrange them in seperate files.
to the editors, cover lettle listing your article's information is enough.
wish you good luck.
cover letter里面说明这是resubmisson?
然后另外一个文件就是回复编辑和审稿人?
回复审稿人的内容(例如说很感激他的comments这些客气话)是在response the comments one by one的时候分别对每个审稿人说 还是在最开头笼统的说两个审稿人的意见对自己很有用?
