On behalf of all the authors, we want to express our thanks to Dr. Sachdev, because he has wrote a comment on the paper "synthesis of cubic boron nitride at low temperature and low pressure conditions". We have learned very much from Dr. Sachdev's comment (referred as "comment" in this article), and find some negligences in our above mentioned paper (referred as "paper" in this article). But Dr. Sachdev also made some obvious mistakes in the "comment", the detailed analysis can be found in the following article.
