For example, if more memory is needed for sort operations and some buffer pools have excess memory, the memory tuner frees up the excess buffer pool memory and allocates it to the sort heaps.

例如，如果排序操作需要更多的内存，而一些缓冲池又有多余的内存，那么内存调优器会释放多余的缓冲池内存，并将它分配给排序堆。

Likewise, when a buffer overflows, the excess data may trample on other meaningful data that the program might wish to access in the future.

同样地，当缓冲区溢位时，额外的资料会摧残程序将来可能要存取的其它有用的资料。

The excess reserves thus seem to have taken on the status of a buffer, rather than actively participating in, and engendering, lending and economic activity.

因此，超额准备金似乎也带有某种“缓冲”性质，而非积极参与（或催生）放贷和经济活动。
