代码审查意见：

1. 格式一致性：

   • 在修改的文件中，# Desktop Environment | DDE | 被改为 # Desktop Environment|dde|，这可能会导致在不同语言文件中格式不一致。建议保持一致的格式，例如使用空格分隔标签和内容。

2. 语言一致性：

   • 在修改的文件中，dde 的大小写不一致，原文件中是全大写，修改后是小写。建议保持语言标签的一致性，如果需要保持全大写，则所有文件中的 dde 都应保持大写。

3. 翻译一致性：

   • 检查其他语言文件中是否有类似的格式或大小写不一致的问题，确保整个项目的翻译和格式保持一致。

4. 注释和文档：

   • 确保文档和注释的格式和风格与项目中的其他文档和注释保持一致，以提高代码的可读性和维护性。

5. 本地化：

   • 如果项目支持多语言，确保所有语言文件都经过本地化，并且翻译准确无误。

6. 版本控制：

   • 在进行文件修改时，确保提交信息清晰描述了修改的内容，以便其他开发者理解变更的目的。

综上所述，建议在修改文件时，保持格式和语言的一致性，并确保文档和注释的准确性和一致性。同时，注意版本控制中的提交信息，以便于团队协作和代码维护。
