三环类抗抑郁剂也能导致如下副作用。
Tricyclic antidepressants also can cause side effects including.
在这样的时候，反射对您来说就不再是一种行之有效的办法——反射将JV m类结构作为信息源使用，因此它仅对已由JVM装载的类起作用。
In these cases, reflection won't work for you — reflection USES the JVM's class structures as the source of information, so it can only work with classes that have been loaded by the JVM.
换句话说，工具提供的视图不仅仅可以显示类和类实例的交互作用，而且可以显示线程、进程和主机之间的交互作用。
In other words, the views provided by the tool are able to present not only the interactions of classes and class instances, but also interactions among threads, processes, and hosts.
在很多情况下，类的相互作用分析足以帮助发现问题，但是您偶尔可能需要进行更深入的对象级别的分析。
In most situations, class interaction analysis (available with the ARM agent) is enough to help find problems, but occasionally you will need to do further profiling at the object level.
您可以在代码的任何地方导入包、类等，它们的作用域限于导入它们的文件。
You can import packages, classes, etc. anywhere in the code, and they are scoped to where you import them.
这可能只是由于幸运地遇到了好天气，或者煤灰一类的烟尘造成的冷却作用阻碍了变暖。
This was perhaps due simply to luck with the weather, or the cooling influence of aerosol particles, such as soot, that blocks warming.
静态函数与静态属性一样，作用域也是类而非该类的对象实例。
Static functions, like static properties, are scoped to the class rather than to object instances of that class.
例如，实际上任何一个面向对象的建模语言都需要定义类，属性，关联，相互作用等概念。
For example, practically any object-oriented modeling language will need to define the concepts of classes, attributes, associations, interactions, and so on.
山峰底部的层叠物中还含有粘土和硫酸盐，这两类物质都是在水的作用下才能形成。
The layers at the base of the mountain contain clays and sulfates, both known to form in water.
C#中，属性通过 .NET反射起作用，这是指类可以进行自我描述的能力。
In C#, attributes work through .NET reflection, which is the ability of a class to describe itself.
当“单个”服务器类加载器策略在起作用时，将使用单个类加载器为服务器上部署的所有应用程序加载大多数类。
When the Single server classloader policy is in effect, a single classloader is used to load most of the classes for all the applications that are deployed on the server.
要让丝类在光学应用上发挥作用，你必须得实施强化。
If you want to use it for optical applications, you need to reinforce it.
与您可能假设的情况相反，即时优化不在创建实例时或方法运行时发生，而是在定义类的作用域内发生。
Contrary to what you might assume, just-in-time does not happen when an instance is created, or methods run, but rather in the scope where the class is defined.
当我们编写单元测试时，我们应该尽量编写没有副作用的代码，IO当然也属于这一类。
When we write unit tests we should strive for code that is free of side effects, and IO certainly falls under this category.
东方饮食结构中的一些成分能够保护心脏，但酱类中的高钠成分则又会抵消这一作用。
While some components of the Oriental diet may protect against heart trouble, the higher sodium content of sauces counter that benefit.
林木和其他类植物可以维持星球适宜温度，但是大气中二氧化碳浓度的增加会减低这种调节作用。
Trees and other plants help keep the planet cool, but rising levels of carbon dioxide in the atmosphere are turning down this global air conditioner.
这种方法的一个有趣的副作用是允许通过闭包访问类的私有成员和受保护成员，这有利于对类执行单元测试。
One interesting side effect of this approach is that it allows us to access private and protected members of a class via a closure, which can be handy for unit testing classes.
我们内脏里的细菌会吞噬糖类和脂肪酸一类的物质，它们通过呼吸作用和发酵作用可以分解此类物质。
Bacteria in our gut gobble up things like sugars and fatty acids, which they can break down either through respiration or fermentation. Respiration provides a bigger energy kick.
涤纶类织品比纯棉类保护作用好点儿，有色布料比白色的保护作用好，但这它们也会提高温度。
Polyester fabrics provide more protection than cotton, and dyed clothing is better than white, but both of those options also crank up the heat.
它的作用在于，您可以使用匿名类来替代您所希望替代的方法；剩下的方法会按默认方式实现。
What's useful about this class is that you can use anonymous classes to override only the methods you want; the rest of the methods are implemented by default.
创建完整大小应用程序的组织包、界面和类结构，即使这些文件的作用只是声明最初实现的类名称和接口。
Create the full-size application's organizational package, interface, and class structure, even if the files do nothing more than declare the class name and the interface it implements initially.
序列图可用于描述类或一组相互作用的类的使用，因而描述了交互所需的协议。
Sequence diagrams can be used to describe the USES of a class or interacting group of classes, thus describing the protocols required for interaction.
