在进行碎片整理操作时，碎片整理程序不会执行独占锁，这样分区对于其他操作来说也是可用的。

The defragmenter does not take an exclusive lock while doing the defrag operation, hence the partition is available for other operations.

比如在分区的条目旁边有一个锁形图标。

Such partitions have a padlock icon next to their entries.

发生这一问题的原因在于数据库内的索引锁定或锁存(例如事务处理日志周围的索引锁定或锁存)，直到该应用程序使用分区数据库为止。

This happens because the index locks or latches within the database (such as those surrounding the transaction log) until the application is using a partitioned database.
