The solution to this situation is to shorten the topic, use the subtitle and divide it into two lines.

1. Shorten the topic: try to simplify the topic or refine the keywords to make it more refined. Ensure that the topic can accurately reflect the core content of the paper.

2. Use subheading: Add subheading under the main heading to explain the specific aspects or scope of the study.

3. Divide into two lines: If the topic really can't be compressed, consider dividing it into two lines, but make sure there are appropriate conjunctions or punctuation marks between the two lines, so that the topic is still a whole.
