  * execTuples.cpp
- *	  Routines dealing with TupleTableSlots.  These are used for resource
- *	  management associated with tuples (eg, releasing buffer pins for
- *	  tuples in disk buffers, or freeing the memory occupied by transient
- *	  tuples).	Slots also provide access abstraction that lets us implement
- *	  "virtual" tuples to reduce data-copying overhead.
+ *	  处理TupleTableSlots的例程。这些用于与元组相关的资源管理
+ *（例如，释放磁盘缓冲区中元组的缓冲引脚，或释放传输元组占用的内存）。
+ *   插槽还提供访问抽象，使我们能够实现“虚拟”元组，以减少数据复制开销。

- *	  Routines dealing with the type information for tuples. Currently,
- *	  the type information for a tuple is an array of FormData_pg_attribute.
- *	  This information is needed by routines manipulating tuples
- *	  (getattribute, formtuple, etc.).

+ *    目前，元组的类型信息是FormData_pg_attribute的数组。
