Memory blocks can be reached in one of two ways -- if the user program holds a reference to that block in a root, or if there is a reference to that block held in another reachable block.
可以以两种方式之一访问内存块 ――或者用户程序在根 (root)中有对这一内存块的引用，或者在另一个可到达的块中有对这个块的引用。
If the reference that the conditional block will use for input does not exist, create it (as explained in the article on adding dynamic data to your Web service tests in the Resources section).
如果条件块为了输入而使用的引用不存在，那么就创建它(这在参考资料部分的文章addingdynamicdatatoyourWebservicetests中有解释)。
The reference tag is useful for catching mis-writes of data to an incorrect block, where the application tag can be used to catch other errors in the software stack.

Inter prediction is used to guess the content of a block by referring to past frames. There are two primary components to inter prediction: reference frames and motion vectors.
帧间预测是利用前面的帧的信息来猜测块的内容。有两个主要组件：参考帧和运动矢量。
To avoid dangling Pointers (the dangerous situation where a block of memory is freed but a pointer still references it), you must delete the object only after the last reference is released.
为了避免悬空指针(一种危险的情况，即一块内存已经被释放了，而一个指针还在引用它)，必须在最后的引用释放之后才删除对象。
