A chunk in term is a contiguous space on disk.
块(chunk)在术语上是指磁盘上的连续空间。
An extent is a block of physically contiguous space.
区段(extent)是一块物理位置连续的空间。
As we saw in the pictorial example, an object needs contiguous space to be allocated on the heap.
正如我们在之前的示意图中看到的，需要为对象分配heap上的连续空间。
The memory is no more a single contiguous space as it is for a traditional non-partitioned environment.
与传统的非分区环境不同的是，内存不再是一个连续空间。
This is a considerably smaller contiguous space to allocate and therefore will most likely resolve the problem.
这样分配的连续空间就要小得多，因此最有可能解决问题。
The next object now requests space on the heap, but there is not enough contiguous space to satisfy this request (see figure 3).
这时，下一个对象开始请求这个heap上的空间，但已经没有足够的连续空间能够满足这一请求(参见图3)。
This entry lets us know that there was an allocation failure, which presents itself when there is not enough contiguous space in the heap to allocate the object.
通过这个条目，我们能够知道有一个分配失败，当heap内没有足够的连续空间可以分配给对象时，就会发生分配失败。
The objects are added to this space until there is not enough contiguous space to satisfy the request for the next object being placed on the heap (see figure 2).
这些对象会被逐渐添加到这个空间，直到没有足够的连续空间能满足将下一个对象放在heap上的要求(参见图2)。
The compact phase is run only in a full GC, which attempts to reallocate all the objects in the heap to a smaller, more compact, and more contiguous space in the heap.
compact阶段只在一个完整的GC中才会运行，在这个阶段，gc会试图将heap内的所有对象重新分配到heap内的一个更为紧缩、更为连续的较小空间。
For example, it is just as costly for an allocator to determine how much total contiguous space would be gained by coalescing chunks as it would be to just coalesce them and then resplit them.
例如，让分配器判断通过合并块能获取多少总共的连续空间的开销和直接合并然后分割它们的开销一样大。
