有关操作、引用以及基本属性的元数据在一个静态初始程序块中被初始化，如清单3所示。
Metadata about operations, references, and basic attributes are initialized in a static block initializer, as shown in Listing 3.
当这个元素等于true 时，它将一个引用分配给Machine对象，而后者将在规则的结果块被用到。
Whenever this element evaluates to true, it assigns a reference to the Machine object that is then used in the consequence part of the rule.
ActionScript在使用一个包(库)之前，先要进行引用，所以例中脚本块的开头有一行“import ”语句。
ActionScript also requires a reference to other packages (libraries) in order to use them; hence the "import" statement at the top of the Script block.
最后，字符串类型是引用类型，因此每个字符串实例都引用一个附加的内存块，以存放实际的字符串数据。
Finally, the string type is a reference type, so every string instance refers to an additional block of memory to hold the actual string data.
所以，如果一个字节序列可以是一个指向一块被分配的内存的指针，那么收集器就将其标记为正在被引用。
So, if a sequence of bytes could be a pointer to a piece of allocated memory, it marks it as being referenced.
大多数情况下，一个条件块依靠一个引用的值发出用户输入动作。
In most cases, a conditional block issues user input actions depending on the value of a reference.
实际上，如果您想访问一个特定的块设备(如磁盘、分区、光盘驱动器等等)，事实上有几个不同的特殊文件可以引用。
In fact, when you want to access a particular block device (such as a disks, partition, CD-ROM drive, etc) you'll actually have several different special files to which you can refer.
确定了与一个特定的bibliographic：topic相关联的代码块，并且给日历源代码添加了引用。
I identified a block of code statements associated with a particular bibliographic: topic and added references to calendar sources.
我在第一个代码块中查看业务服务引用的所有绑定模板，并找到具有“http”url类型的绑定模板。
In the first code block I looked at all the binding templates referenced by the business service and found the one which had a URL type of "HTTP".
这个函数的参数定义一个文件系统结构(file_system_type)的引用，这个结构定义文件系统的名称、一组属性和两个超级块函数。
This takes a single argument defining the reference to a file system structure (file_system_type), which defines the name of the file system, a set of attributes, and two superblock functions.
采用一个边栏块来显示有关引用和Google搜索的信息可以实现的功能非常可怕：RockyOliver的LotusGeekblog就在上面采用了边栏的方法。
What you can do with the side-column blocks to display information about referrers and Google searches is awesome: Rocky Oliver's Lotus Geek blog takes the side-columns way over the top.
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。
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.
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。
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.
