+笔记：ERC721.sol：ERC721标准的实现，提供NFT核心功能，如所有权管理、转移等。
+ERC721URIStorage.sol：扩展功能，用于存储每个NFT的元数据URI（如指向JSON文件的链接，包含图片、描述等）。
+ERC721Burnable.sol：添加“销毁”功能，允许永久删除NFT，减少流通量。
+Ownable.sol：实现访问控制，限制特定功能（如铸造）仅限合约拥有者调用。
+EIP712.sol：支持EIP-712标准，用于结构化数据签名，可实现无gas交易（如签名授权）。
+ERC721Votes.sol：为NFT添加治理功能，允许NFT持有者参与投票（如DAO治理）。
