[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

请帮忙修复PaddleScience中所有.py文件中的基础错误，比如

1. docstring中的参数类型和实际参数type hint没对齐
2. docstring中的参数名字和实际参数名字没对齐
3. docstring中的参数个数和实际参数个数没对齐
