Low-level doctoral degree: The thesis idea is equal to the undergraduate graduation design; the number of papers is worrying, and I worry about delaying the graduation all day long;
Ordinary doctoral degree: average mathematical ability, do brainless scientific research, and stitch and patch it on other people's ideas; many papers with similar ideas, but they just cannot publish high-level journals, or a high-level article that is lucky;
Excellent doctoral degree: good mathematical foundation, extensive knowledge in scientific research, and can dig out innovative points that others cannot imagine from their existing knowledge, but they still cannot make breakthroughs in theory; high-level papers are soft, and the citations are rising exponentially;
Big Niu: Very good mathematical foundation, major breakthroughs in theory.
The domestic low-level doctoral students are concentrated in the admission stage of direct doctoral students/master doctoral students/doctoral students. If you don’t work hard and the academic level of your supervisor is worrying, it is likely that it will still be low after many years;
Some old doctors think they are ordinary doctoral students, but in fact they are low-level doctoral students;
There are too many low-quality papers for low-level doctoral students, and they will naturally be promoted to ordinary doctoral students. The two essentially have only a quantitative gap and no qualitative leap.
When you read the three or four doctoral students, those who have good scientific research tastes on the basis of a solid foundation in the past few years can be sublimated into excellent doctoral students;
Many professors born in the 1960s and 1970s who have the right to speak in the academic world are not proficient in this field, and are essentially ordinary doctoral students;
Some post-80s and 1990s green peppers and 1970s in various universities have significantly better academic taste than those born in the 1960s and 1970s, and these are excellent doctoral students.
