Hi&nbsp;Qinwu Xu<br /><br />I have uploaded your edited document and hope that you find the suggestions helpful. If you have any questions, please send me a message via Editor World.<br /><br />I carefully read your document several times and made changes to aid flow and correct minor grammatical lapses. It is, of course, a very technical document and I wanted, above all, not to change your meaning. So please check very carefully. It is, in any case, an excellent submission -- those parts, anyway, that I understood.&nbsp;<br /><br />I hope, together, we've met your deadline.<br /><br />Microsoft Word displays tracked changes and comments by default. <br /><br />To review the edited document without showing tracked changes, click Review on the Microsoft Word menu bar. Then select Final: Show Markup and click the dropdown arrow. Choose Final. To show tracked changes again, click Final: Show Markup.<br /><br />Best wishes - TypeRighter (aka George)<br /><br />I am usually available for editing between 6:00 am and 10:30 pm. If my status is set to unavailable, you can still send a message to me via Editor World.<br /><br /><br />
