Path one-find a mentor.
Since we can't change the topic, we can only continue to bite the bullet and finish the next paper.
If you can't get the experimental data, you should hurry to find a tutor. The tutor's main task is to guide students to finish their graduation thesis. You need to sort out all your problems before meeting your tutor. Don't come up and ask the tutor what to do, and the paper data can't be worked out.
Instead, ask the tutor with the phenomena and questions that appear in your experiment, and ask the tutor to give advice when you have questions to answer.
If you can't get an appointment with a tutor, you can go directly to the tutor's office to find a tutor. University is an active learning process. In the graduation thesis, you can only take the initiative.
The second way-looking for literature.
Reading literature is the most reliable method in the case of lack of graduation thesis materials and inability to complete the thesis. You can find some articles, periodicals, doctoral dissertations and so on related to your research topic through libraries and literature retrieval websites. And check how the data in the literature is collected, how it is processed, and how the research process is.
By paying attention to the charts in the literature, we can get some useful information and find the idea of the paper. In addition, you can also pay attention to the division of article subtitles to help you build a framework and fill in the content of the paper. Commonly used literature tools are: HowNet, Google Academic, school library and industry report. Documents are usually searched accurately by keywords, subject words and authors.
