We approximate the free memory after a garbage collection cycle by using algorithms that analyze the variance of free memory statistics.

通过使用分析可用内存统计信息变化的算法，我们可粗略计算垃圾收集周期之后的可用内存。

A generational collector is free to use a different collection strategy for different generations and perform garbage collection on the generations separately.

分代收集器对不同的代可以自由使用不同的收集策略，对各代分别进行垃圾收集。

The garbage collector performs a collection in an attempt to free address space in generation 0 for the object.

垃圾回收器执行回收，尝试为对象释放第0级托管堆中的地址空间。
