基于对象的引用计数和基于单一对象的多重接口管理都是有用的概念。
Reference counting on objects and managing multiple interfaces on a single object are both useful concepts.
如果没有其他的引用指向对象，那么它的引用计数达到0，这是释放。
If no other reference points to the object, then its reference count reaches 0 and it is deallocated.
如果对象的引用计数是零，那么它就是垃圾(用户程序不可到达它)，并可以回收。
If an object's reference count is zero, it is garbage (unreachable from the user program) and can be recycled.
当两个对象互相引用时，就构成了循环引用，其中每个对象的引用计数值都被赋1。
A circular reference is formed when two objects reference each other, giving each object a reference count of 1.
此方法使您能够强制RCW引用计数释放，以便它按照您的所需准确发生。
This method enables you to force an RCW reference count release so that it occurs precisely when you want it to.
除了垃圾收集之外，通常还有其他两种方法用于处理别名问题：引用计数和所有权管理。
Besides garbage collection, two other approaches are commonly used to deal with the problems of aliasing: reference counting and ownership management.
在引用计数系统，每个所引用的对象都会保留一个计数，以获悉有多少对象正在引用它。
In a reference counting system, each object referenced maintains a count of how many objects are referencing it.
如果附件存在于多个数据库中，该附件在每个服务器分区中仅存储一次，同时增加引用计数。
If an attachment exists in multiple databases, the attachment is stored only once per server partition, and the reference counts are increased.

Then the methods of the adoption to quote from to count, operating the marking etc are introduced.
在同时使用了垃圾收集和引用计数的混合系统中，将会发生泄漏，因为系统不能正确识别循环引用。
In a hybrid system, where both garbage collection and reference counting are being used, leaks occur because the system fails to identify a circular reference.
