英汉例句

• it contains an invariant -- that the lower bound is always less than or equal to the upper bound.

  它包含了一个不变式 ——下界总是小于或等于上界。

• for example, the document uris are long strings that consist of an invariant part and a part that is document-specific.

  例如，文档uri是长字符串，由一个不变的部分和一个与文档相关的部分组成。

• the invariant parts could be moved into a separate table to save space.

  可以将不变的部分转移到一个单独的表中。

• a method invariant must hold before and after the method executes; a field invariant must be true for a field for the life of the object.

  方法在调用之前和之后必须保持不变；字段则在对象的整个生命周期中保持不变。

• by the way, notice the comments asserting what invariant we expect to hold in the body of each if statement.

  顺便注意一下断定每个if语句正文中希望保留的不变量的注释。

• it is important to note that the invariant checking is performed twice, both before and after the service execution.

  一定要注意不变量检查执行了两次，是在服务执行之前和之后。

• methods and constructors can also have invariant tests.

  方法和构造函数也可以有不变条件测试。

• container directives (policies) that are invariant for all instances of the implementation.

  对所有实现实例都保持不变的容器指示（策略）。

• for example, in an accounting application, consistency would include the invariant that the sum of all asset accounts equal the sum of all liability accounts.

  例如，在记账应用程序中，一致性可能包括所有资产账户的总和始终等于所有负债账户的总和这个不变式。

• you can also write contract tests on classes or aspects, where you can define tests on constructors and invariant conditions on instance fields.

  也可以在类或方面上编写合约测试，在这些类或方面中可以在构造函数上定义测试，在实例字段上定义不变条件。

• using property files or api calls at run time, you can enable or disable all tests, just precondition tests, just postcondition tests, or just invariant tests.

  在运行时使用属性文件或api调用，可以开启或禁止所有测试，即前置条件测试、后置条件测试或者不变条件测试。

• finally, invariant tests assert conditions that never change.

  最后，不变条件测试断言永远不变的条件。

• notice that the invariant and other tests refer to an implied balance field, even though an interface can't define fields.

  注意，虽然接口不能定义字段，但不变条件测试和其他测试引用了一个隐含的余额字段。

• the contract specification for bankaccount includes a class-wide invariant that the balance must always be greater than or equal to zero (sorry, no overdrafts allowed!).

  bankaccount 的接口规范包含一个类范围的不变条件测试，即余额总要大于或等于0（对不起，不允许透支）。

• the invariant space has to be as well a deformation of a classical space, a deformation that makes it noncommutative.

  这些不变的空间同样也是经典空间的变形，它们通过这种变形成为非对易空间。

• and, so this number two is somehow an invariant that you can associate to this kind of shape.

  其中第二条在某种意义上是,一个与这种形状有关的不变量。

• consistency: a transaction preserves all the invariant properties (such as integrity constraints) defined on the data.

  一致性：事务保持数据上定义的所有不变的属性（如完整性约束）。

• for example, the default invariant condition for a field requires the field to be non-null.

  例如，字段的默认不变条件要求字段不能为空。

• crucially, this was true at all frequencies, which means the phenomenon is scale invariant - the other key criterion for self-organised criticality.

  最重要的是，所有的频率都是这样，意味着这种现象是规模不变的-自我组织临界的另一个重要标準。

• a class invariant must hold before and after all method calls (once the object is constructed).

  类在方法调用之前和之后必须保持不变（一旦对象已经构建）。
