逻辑上，两个块可以有连续的块地址，但不能确定实际的信息存在哪里。

Logically, two blocks may have consecutive block addresses, but this has no bearing on where the actual information is electronically stored.

以二维逻辑块地址为基础，对体全息数据存储文件系统空间分配的连续性进行了研究，提出了“顺序连续”和“随机连续”的概念。

By researching the continuity of file data-block allocation on two-dimensional logical block address, the concepts of "sequence continuity" and "stochastic continuity" were presented.
