One is to publish more than two papers in core journals as the first author; Publishing papers as the first author in core journals is a hard condition for doctoral graduation. If it is published in a class of journals, it can be counted as two, and other types of core journals can only be counted as one. Second, complete all credits within the specified time; The standard length of study for doctoral students is three years. If the doctoral degree is two years, doctoral students need to complete all credits and pass the defense within the prescribed study period before applying for graduation. Third, there is no record of academic misconduct; When doctoral students publish papers, they should ensure that the papers are scientific and reliable, and there can be no fraud and plagiarism. If they are found to have academic misconduct, they will be disqualified.

Doctoral students, that is, doctoral students, are graduate students studying for doctoral degrees and are the highest level of postgraduate education. In people's daily life, they are admitted to doctors, read doctors and so on. Refers to a doctoral student. Strictly speaking, students who have not obtained a doctorate can only be called doctoral students; Only those who get a doctorate are real doctors. Therefore, according to international practice, in formal occasions, only those who have obtained a doctorate can be crowned with the title of "doctor"; This restriction can be waived in informal situations.

China's higher education is divided into three academic levels: junior college, undergraduate and postgraduate, with postgraduate as the highest, but postgraduate can be divided into master students and doctoral students according to their academic qualifications, and doctoral students are the highest academic level in higher education. When a doctoral student graduates, he can get a full-time doctoral diploma and a doctoral degree certificate. Those who study for a doctoral degree on the job with the same academic qualifications can only obtain a degree certificate, and their academic qualifications are still the same, such as undergraduate or master's degree. At present, the scale of doctoral education in China is controlled, forming a ratio of 10: 1. In addition, in order to facilitate understanding, we can refer to the policy classification of full-set academic education in China: middle school students include junior high school students and high school students, college students include junior college students and undergraduates and graduate students, and graduate students include master students and doctoral students. Doctoral students are referred to as doctoral students for short, and doctors in people's daily life refer to doctoral students. Doctoral students are the highest academic qualifications and degrees in China at present, and postdoctoral students are not students, but the names of staff. Although its name has the word doctor, it has nothing to do with students, but its essence is the identity of the staff.
