If the garbage collector discovers an object that is weakly reachable, the following occurs.

如果垃圾收集器发现了弱可及对象，就会出现下列情况。

Weakly reachable: an object that is not strongly or softly reachable and can be accessed through a weak reference.

弱可及对象(weakly reachable)：不是强可及对象也不是软可及对象，并且能够通过弱引用访问的对象。

Note, however, that it may take multiple runs of the garbage collector before it finds and frees a weakly reachable object.

然而，请注意，垃圾收集器可能要运行多次才能找到并释放弱可及对象。
