Dear Mr. Martin,

Thanks for your excellent work of the edition on our manuscript. Your work made significant improvements in our paper. We originally planned to send it to you for a second revision. But due to our problem of the delay, we have to resubmit the paper right now and might not send it to you for the second revision. We are very sorry about that and hope you can understand.

We hope that you could consistently help us with our future manuscripts and publications. Thanks a lot!

Best regards,

Menghua Deng
