Foreign language documents are of great help to scientific research, mainly in the following aspects:

1. Provide the latest research progress: Foreign language literature usually contains the latest research results and development trends, which can help researchers understand the international research hotspots and frontier fields, thus guiding their own research direction and topic selection.

2. Broaden the research horizon: By reading foreign literature, researchers can get in touch with the academic viewpoints and methods of different countries and regions, which is helpful to broaden the research horizon and improve the innovation ability.

3. Learn advanced research methods and technologies: Some advanced research methods and technologies are usually introduced in foreign literature. These methods and technologies may not be popularized or applied less in China, and the quality and efficiency of scientific research can be improved through learning and reference.

4. Promote academic exchanges and cooperation: Reading foreign language documents will help researchers to establish contact with their international counterparts, promote academic exchanges and cooperation, and promote the development of scientific research.

5. Improve the level of thesis writing: There are often high-quality foreign papers and research reports. By reading and studying these documents, you can improve your writing level and expression ability.

6. Cultivate interdisciplinary thinking: Foreign literature often covers a wide range of research fields. By reading these documents, researchers can cultivate interdisciplinary thinking ability and help solve complex scientific problems.

7. Enhance academic influence: Publishing foreign documents is an important way to enhance academic influence. By publishing papers in international journals, you can expand your academic influence and lay a foundation for future scientific research and career development.

In a word, foreign literature is of great help to scientific research, and researchers should make full use of foreign literature resources to improve their scientific research ability and level.
