此引用必须单一、明确，不会导致项目之间循环引用。
This must be a single, unambiguous reference that does not cause circular references among projects.
通常，都不希望出现循环引用，因为它们引入了复杂性和强耦合性。
In general, circular references are considered undesirable because they introduce complexity and tight coupling.
在清单2中，通过调用外部函数myfunction创建循环引用。
In Listing 2 a circular reference is created by calling the external function myFunction.
虽然这种解决方案总的来说还算有效，但在循环引用方面却存在一些盲点。
Although this solution is generally very efficient, it has a blind spot when it comes to circular (or cyclic) references.
表面上看似循环引用—t扩展经过t参数化的内容—实际上并不是真正的循环。
The seeming circular reference - where t extends something parameterized by t - is not really circular at all.
这个函数可以用于在一个元素上存取数据而避免了循环引用的风险。
This function is used to get stored data on an element without the risk of a circular reference.
公式包含循环引用（计算列引用其本身）。必须删除或更改循环引用。
The formula contains a circular reference (the calculated column refers to itself). You must remove or change the circular reference.
当两个对象互相引用时，就构成了循环引用，其中每个对象的引用计数值都被赋1。
A circular reference is formed when two objects reference each other, giving each object a reference count of 1.
如果这个页面在同一个文件夹中，那么它就会通过多页面Portlet产生循环引用。
If this page was contained in that folder, it would create a circular reference to itself through the Multi-page portlet.

The circular references between Object A and Object B are handily represented by the flexible SOAP encoding rules.
表达式可以引用其他表达式列，但循环引用(其中两个表达式相互引用)将产生异常。
Expressions can reference other expression columns; however, a circular reference, in which two expressions reference each other, will generate an exception.
在同时使用了垃圾收集和引用计数的混合系统中，将会发生泄漏，因为系统不能正确识别循环引用。
In a hybrid system, where both garbage collection and reference counting are being used, leaks occur because the system fails to identify a circular reference.
