@liang_meng_fei The problem occurs because fonts required for rendering the document are not available in the environment where the document is converted to PDF. To build an accurate document layout the fonts are required. If Aspose.Words cannot find the fonts used in the document the fonts are substituted. This might lead into the layout and appearance difference.
Please see the following articles to learn where Aspose.Words looks for fonts and how to install fonts on Linux:
