What you want to ask is why you can't find the dissertation knowledge network of Southeast University. There are three reasons.

1. This paper is included in the self-built database of our school.

2. The thesis is in the transition period of collecting papers and has not been collected. Most college graduates graduate in April-June in spring, and only receive them in the second half of the year around 10.

3. The paper is in other duplicate checking software databases and does not belong to HowNet.
