Dear Editor,

Thanks very much for your kind work and consideration on publication of our manuscript

entitled "论文标题" (ID ；论文编号). On behalf of my co-authors, we would like to express our

great appreciation to editor and reviewers.

Moreover, although this is a serious problem because the manuscript is already accepted for

publication, we are wishing to add Dr. 新增作者名字 as an extra author to the manuscript and

the new title page is sent as an attachment. 新增作者名字 is a new member of my group and

contributed much in the revised version of our manuscript. After we received the referee's

comments, he/she did a great job for the expansion of literature review so as to provide a deeper

insight into the related published work and hence establish the contribution of this paper with

respect to other publications tackling the problem. He/She also recalculated all the noise

coefficients with a precision of four digits after the decimal point, as listed in Table II, Table III,

Table IV and Table VII. Without her hard work, we could not finish the revised version in several

days. However, when I changed the authors' list, I forgot to add her as the fifth author.

Would you please to give us a chance to add Qin Gao as a new author to the paper If you give

us this chance, we will be grateful.

Best wishes,

Yours sincerely,

XXXXX
