I use a block cipher algorithm for encryption that requires the clear data bytes to be in blocks of 8 bytes, so I pad the last incomplete block with some characters.
我对需要将明文数据字节放在8字节块的加密使用块密码算法，所以我用一些字符填充最后一个不完整的块。

When the server started up again after the crash, the XFS code would look at the journal, realize the situation, and fill those incomplete data blocks with binary zeros as a security precaution.
As minimum knowledge units, maximal consistent blocks are very useful for knowledge representation, attribute reduction, granular analysis and knowledge acquisition in incomplete information systems.
