您要查找的是不是：
- Every concrete class that implements the interface must supply the implementation details for theses members. 实现该接口的每个具体类都必须提供这些成员的实现细节。
- The generated delegation class is a concrete class instead of an abstract class. 生成的委托类是具体类而不是抽象类。
- A class that is not a MustInherit class, one that can be instantiated, is called a concrete class. 非MustInherit类可以实例化,称为“具体”类。
- A concrete class is a class that exposes, rather than hides, its implementation. 具体类会暴露而非隐藏其实现细节。
- In addition, we use OO(Object-Oriented) software modeling method, and describe the whole process with UML(Unified Modeling Language) from requirementanalyzation to concrete class design. 另外，我们使用面向对象的软件建模方法，用UML语言描述从需求分析到具体类的设计的整个过程。
- Dependency Inversion Principle Depend upon abstractions. Do not depend upon concret classes. 依赖倒置原则要依赖抽象。不要依赖实现类。
- Capture highlevel, stable concepts in abstract classes and interfaces and provide implementations using concrete classes. 在抽象的类和接口中捕捉高级、稳定的概念，并用具象类实现。
- Abstract Factory Design Pattern (Sample - An abstract factory provides an interface for creating families of related objects without specifying their concrete classes. 一个抽象工厂提供了用于创建一系列相关对象的接口，而不用说明它们的具体类。
- Because these are merely Java interfaces and not concrete classes, the EJB container must generate classes for these interfaces that will act as a proxy in the client. EJB容器将为这些接口提供对应的实现类以充当客户远程代理，当客户端调用这个生成的代理类的某个方法时，代理类内部会将此调用的方法和参数封装成一个消息发送给服务器。
- The concrete walls are reinforced with steel rods. 混凝土墙是用钢筋加固的。
- We need a hoist to lift the concrete blocks. 我们需要一台起重机来吊起混凝土块。
- The machine rests on a bed of concrete. 机器安装在混凝土基座上。
- That new concrete building is an abomination. 那座新混凝土建筑是个讨厌的东西。
- The road was paved with concrete. 路面由混凝土铺成。
- Have you got any concrete proposals? 你有没有具体的建议呢?
- The house is made of stone, not concrete. 那房子是石造的，不是混凝土造的。
- Tom tumbled over and hit his head on the concrete. 汤姆摔倒，头撞到水泥地。
- The statue rests on a bed of concrete. 这座雕像立在混凝土的基座上。
- The front of the house was faced with concrete. 房屋正面涂著一层混凝土。
- In the concrete, the theory is far from perfect. 实际上,这一理论远远不够完善。
