例如，这种理论模型允许用更有效的等价操作来代替关系代数操作同时不影响结果。
This theoretical model allows, for example, that relational algebra operations to be replaced by more efficient equivalent operations whereas not interfere with the result.
该操作的一个等价实现方式如下所示。
要模仿JSF默认错误处理和验证，还必须配置Struts使用验证器框架，或者在ActionForm上的validate方法中实现等价的操作。
To mimic JSF's default error handling and validation you would have to configure Struts to use the validator framework or implement the equivalent in the validate method on an ActionForm.
在例4中显示的同步操作的等价异步回调包含如下一个请求操作。
The asynchronous callback equivalent of the synchronous operation shown in Example 4 consists of a request operation like this.
通常，现有应用程序的操作包含了业务流程的各种需求，使其成为了设计或者实现更改的等价物。
Often the operation of existing applications has taken over the business process requirements to become the equivalent of design or implementation changes.
可以操作声子并只让它们向一个方向流动的设备正在被建造，这是二极管的热等价物。
Far from it. Devices are being built that can manipulate phonons, allowing them to flow in one direction only, for example - the thermal equivalent of a diode.
操作数的顺序与等价的中缀表达式中操作数的顺序一致。
The operands are in the same order that they would be in the equivalent infix expression.
此操作等价于获取使用names . nsf数据库中的Person表单创建的所有文档。
This action is equivalent to obtaining all documents that were created with the Person form in the database names.nsf.
因此，如果您正在使用一台基于Red Hat 的计算机，那么请确保为特定的 *nix操作系统安装了 python-dev（或者其等价物）和PythonHeader文件。
So if you are on a Red Hat-based machine, make sure you install python-dev (or the equivalent) and Python header files for your specific *nix OS.
为所有操作提供等价的键盘操作。
同时证明了属性神经网络与属性坐标系的等价性，从而为属性推理提供可操作的数值推导方法。
The equivalence of attribute neural networks and attribute coordinate space is proved, and a method of numerical value inference is provided for attribute inference.
我不知道如何操作是等价的。
操作几何上定义为交换分子中等价部分的方式。
Symmetry operations are geometrically defined ways of exchanging equivalent parts of a molecule.
这种直接计算迭代器的方法，与用迭代器逐个元素自增操作到达中间元素的方法是等价的，但前者的效率要高得多。
It is more efficient to calculate this iterator directly than to write an equivalent program that increments the iterator one by one until it reaches the middle element.
当前大多数软件处理文件系统的方式和操作系统如何处理没有什么两样，这等价于要求你像汽车机械师一样对待你的车子。
Currently, most software applications treat the file system in much the same way that the operating system does. This is tantamount to making you deal with your car in the same way a mechanic does.
注意到实际的内存操作的执行可能很好的等价于一些完全不同的高级语言的代码的执行；
Notice that the actual memory operations performed could equally well have been performed by some completely different high level language code;
