   According to the "Requirements of Nanjing Tech University on the Proposal Report of Graduate Students", doctoral students of this disciplinecan only make the proposal report after submitting the "Safety Risk Assessment Report of the Experiment for the Opening Assessment of Graduate Students in the College of Materials Science and Engineering". The proposal report of thesis should be completed before the end of the third semester, and the time between the proposal report and the application for thesis defense is generally not less than1.5years. The numberof the proposal report words should be about 5000 ; more than 150 main references should be read, among which there should be at least 2/3 foreign references.The contents of the proposal report should include: (1) the research significance of the topic, the current situation at home and abroad; (2) the accumulation of work related to the topic and the existing research achievements; (3) the difficulties in the topic and the key problems to be solved; the proposed research methods, technical routes, experimental programs and their feasibility; (4) the planned progress and expected results.

   The proposal report conference should be held centrally and openly within the scope of the discipline, and the proposal report should be evaluated by an assessment panel consisting of three to fiveexperts. The members of the review group are experts with senior titles in relevant disciplines, among which there should be at least70% of doctoral supervisors, one to twoenterprise experts (with senior titles) can be invited for major scientific research projects in cooperation with industrial and mining enterprises, and doctoral supervisors of relevant disciplines should be invited to participate in the selection of topic for interdisciplinary theses. For those who pass the assessment of proposal report, the revised proposal report and thesis work plan should be submitted to the college for record by the end of the third semester after being approved by the chairman of the Degree Evaluation Sub-Committee; for those who fail to pass the assessment of proposal report, the proposal report can be made up within 6 months, and for those who still fail, the college will set up an expert group to help rectify the proposal report until it passes the assessment. After the proposal report is approved, it is generally not allowed to change the topic at will. If there is a major change in the topic of the thesis, the graduate students must write a written report and reorganize the proposal report conference after the supervisor agrees, so as to ensure the frontier and innovation of the topic.

   3. Mid-term assessment

   The mid-term assessment of doctoral students is a comprehensive assessment and evaluation of their ideological and political performance, course study, scientific research progress and research ability since their enrollment, after their course study and proposal report are basically completed, to determine whether they are qualified to continue their doctoral studies. Those who do not attend the mid-term assessment for no reason may not apply for extension and will be treated as failing the mid-term assessment. For the mid-term assessment of doctoral students, doctoral students should firstly make personal summary and fill out the assessment form, and then the college will organize experts to conduct the assessment. The doctoral students with "excellent" or "qualified" results will pass the mid-term assessment and be allowed to enter the doctoral thesis stage and continue their doctoral studies according to the plan.

   Each doctoral student has two opportunities to be assessed. If the first assessment result is "unqualified", the doctoral students will be given a diversion warning and must attend the next mid-term assessment; if the second assessment is still unqualified, they are not suitable for further cultivation and will be disqualified from pursuing doctoral degree; among them, if students in the full-time combined master and doctor degree program are suitable for transferring to master students cultivation, they can pursue master's degree according to the requirements of master students cultivation upon their own application. The mid-term assessment of doctoral students is held at the end of the fourth semester or the beginning of the fifth semester, and they can only apply for the thesis defense one year after passing the mid-term assessment.

   The mid-term assessment of doctoral students is carried out in accordance with the Implementation Measures for Mid-term Assessment of Doctoral Students of Nanjing Tech University and the Implementation Plan for Mid-term Assessment of Doctoral Students in the College of Materials Science and Engineering.

   4. Pre-defense (pre-review)

   The pre-defense of doctoral students is openly conducted within the first-level discipline of materials science and engineering, and is reviewed by an assessment panel composed of fiveexperts in the discipline or related disciplines. Doctoral students should submit the application for pre-defense of thesis to the graduate secretary beforeMarch 5/September 5every year, and the graduate secretary will arrange the review experts, secretary and time for the pre-defense. After the pre-defense time is set, doctoral students should submit the first draft of the thesis to the pre-defense secretary beforeMarch 10/September 10, and the pre-defense secretary will send it to the review experts and post the pre-defense notice. Graduate students who have completed the pre-defense should revise the problems in the thesis writing according to the opinions put forward by the assessment team, and after the supervisor (team) confirms it, send the Registration Form of Pre-defense Situation to the chairman of the pre-defense for evaluation. Only after passing the evaluation, can the revised thesis be submitted for repetition rate check and blind review within the time specified by the university; if the revised thesis fails to pass the evaluation, graduate students cannot submit the thesis for repetition rate check and blind review within the time specified by the university, and they must make substantial adjustments and improvements according to the opinions put forward by the assessment team for the problems in the research work of the topic and the writing of the thesis under the guidance of the supervisor (team), and then submit the application for the pre-defense of the thesis again.

   The requirements for the pre-defense of doctoral students are detailed in the Implementation Measures of the College of Materials Science and Engineering on the Pre-Defense of Doctoral Theses.
