You write a big paper, which is a very difficult process, because it takes one or two years. Because the experiment is periodic, from the preparation of the experiment, the process of the experiment, the collection of data and the processing of experimental data, including some social sciences, it is necessary to conduct social surveys to collect data, then run the model, and so on, and finally write a dissertation. The number of words in a dissertation is more than 6.5438 million, which takes a long time. Another degree thesis is more difficult, which is reflected in blind evaluation. If the quality of your thesis fails to pass the external evaluation, you are not qualified to apply for a degree defense, and you will not get a degree.
2. The reason why it is difficult for doctors to graduate 2. It is difficult to publish a small paper.
Reflected in:
(1) The competition for submitting small papers is fierce. Every publication, especially the better ones, has fierce competition. Because there are many contributors, everyone comes up with good publications. Then, there is a question of the recruitment rate of manuscripts. For example, some journals receive 1000 manuscripts a year, and may only employ 200 in the end. The difficulty can be imagined, and it is difficult to produce good journal papers.
(2) The publication cycle of small papers is relatively long, and some journals last for several months, so it is generally difficult for student parties to wait, especially those with relatively long periods. Many schools stipulate that doctoral graduates must publish papers in a certain level of journals, and some also have requirements on the number of papers.
(3) The quality requirements of this kind of published small papers are relatively high. Innovation is required, but the layout of the publication is limited. Under this constraint, only papers with higher quality can be published, so how can you reflect the high quality of your papers? It is not easy to do this, no matter from topics, materials, methods, angles to writing.
Many doctors can't graduate, but they can't send out small papers.
