用于垃圾收集的标记和清扫阶段的GC暂停时间基于堆上的活动对象的数量。
This style of collector has an important benefit: by moving live objects with each collection, the nursery area is implicitly compacted with each collect.
这种风格的收集器有一个重大好处：通过在每次收集时移动活动对象，托儿所区域在每次收集时都被隐式压缩。
It conceptually records the heap's state at the beginning of a collection cycle and preserves all live objects at that point as well as those allocated during the current cycle.
它在收集循环开始时在概念上记录堆的状态并保留当时的和当前循环中分配的所有活对象。
There might be lots of free memory, but if it is in small slices interspersed with live objects then no individual piece might be large enough to satisfy a particular allocation.
尽管可能有大量闲置内存，但如果它们只是一些小块，其间夹杂着活动对象，那么可能没有哪个碎块大到足以满足某个特定分配需求。
A minor collection will copy live objects from Eden and one of the survivor semi-spaces into the other survivor space, potentially promoting some objects to the older generation.
小的收集将活的对象从Eden和一个生存半空间复制到另一个生存半空间，并可能提升一些对象到老的代。
Compaction can also be done in parallel, but it results in a less efficient packing of the live objects — instead of a single block of free space, several smaller ones might be created.
压缩也可以并行执行，但这会降低活动对象的打包效果，可能会生成几个较小的闲置空间，而不是一整块闲置空间。
Copying collection has the advantage of only visiting live objects, which means garbage objects will not be examined, nor will they need to be paged into memory or brought into the cache.
复制收集的优点是只访问活跃的对象，这意味着不会检查垃圾对象，也不需要将它们页交换到内存中或者送到缓存中。
Her idea is: live a life and try not to create any rubbish; use different kinds of ways to save the environment, such as stopping the use of one-off objects; giving unwanted things to others or donating these things to organizations like the Red Cross.
她的想法是：好好生活，不制造一点垃圾；采取不同的方式拯救环境，比如停止使用一次性物品；把不想要的东西给别人，或者捐给像红十字会这样的组织机构。
In the mark phase, all the "live" objects are added to mark vector.
在标记阶段，将所有“活的”对象添加到标记向量。
Set against this is the fact that we clearly live in a society awash with materialism, where objects are valued way beyond their possible contribution to our happiness.
与之相对的是，我们真实地生活在一个用物质堆砌的社会，在这里，衡量事物的方式远不止它们对我们幸福感的可能性贡献。
This is because a copying collector does not need to visit or copy dead objects, only live ones.
这是因为，拷贝收集器不需要访问或拷贝死对象，只处理活动对象。
The mark phase is responsible for tracing through all objects visible to the application and marking them as live to prevent them from having their storage reclaimed.
标记阶段负责跟踪应用程序可见的所有对象并将它们标记为活的，以免回收它们的存储。
After the first collection, free heap memory is primarily the result of objects that were once live but are now dead.
