In the process of blind evaluation, it is very important to avoid the problem of paper grade pictures. Here are some suggestions:

1. Use alternative methods: Try to use text descriptions, tables or charts to show your research results instead of just relying on pictures. This can ensure that even if the picture can't be displayed, the reviewer can still understand your research results.

2. Provide a high-resolution version: When submitting a paper, make sure to provide a high-resolution result picture. In this way, even if there is a problem in the review process, the examiner can ask you to provide a higher resolution version.

3. Embedding the picture into the text: Embedding the generated picture into the text instead of submitting it as a separate file. In this way, even if the picture can't be displayed, the reviewer can still understand your research results by reading the text.

4. Use professional image processing software: Use professional image processing software (such as AdobePhotoshop) to edit and optimize the generated images. This can improve the picture quality and reduce the possibility of problems in the blind test.

5. Add metadata to the picture: Add metadata to each result picture, including experimental conditions and parameter settings. In this way, even if the picture can't be displayed, reviewers can understand your research results by looking at the metadata.

6. Discuss with your tutor or peers: Before submitting your paper, discuss your research results with your tutor or peers to ensure that they can understand your research results. If possible, have them check your paper to make sure you haven't missed any important information.

7. Prepare in advance: Before submitting the paper, make sure that you have prepared all possible problems and take measures to solve them in advance. For example, you can contact the editorial department of the journal in advance to understand their requirements for paper format and pictures.

8. Maintain communication: maintain communication with the editorial department of the journal during the blind review process. If there are problems with your pictures, provide them with high-resolution versions or other alternatives in time.
