Generally speaking, the graduation of a doctor of engineering requires that the sum of the influence factors of doctoral thesis is greater than ten, or that two scientific research papers above the second area of SCI are published, so as to be approved for graduation. Before graduation, doctors need appraisal results, and only doctors who have passed the examination are qualified to defend and apply for papers, which is quite difficult.
