Variables are strongly typed, and there is class-based inheritance.
变量都是强类型的，还有基于类的继承。
Figure 2 is simply pointing out the concept of Class, which is a highly specialized element that is related to interface and data type (through its inheritance from Classifier).
图2简单地指出了Class的概念，这是一种和接口以及数据类型有关(通过从Classifier继承)的高度专业化的元素。
Inheritance is the means by which objects of a class can access member variables and functions contained in previously defined class, without having to restate those definitions.
继承是一种方法，通过它，类的对象可以访问以前精确定义过的类中的成员变量和函数，而不用重新声明那些定义。
ActionScript 2.0 was introduced in Flash 7, which was strongly typed and allowed class-based programming features, such as inheritance, interfaces, and strict data typing.
在Flash7中引入了ActionScript 2.0，这是一种强类型的语言，支持基于类的编程特性，比如继承、接口和严格的数据类型。
Object-Oriented is a kind of technology basing on the concept of object, class, instance and inheritance, etc. It deals with problems according to the connected objects.
面向对象是依据问题中涉及的对象来看问题，是一种基于对象、类、实例和继承等概念的技术。
In inheritance, the derived class receives the base class member variables and methods. This means that an order of inheritance must be followed during the construction of an object.
在继承中，派生类接受基类的成员变量和方法。这表示继承的顺序必须在对象构造的时候被遵守。
Using the encapsulation, inheritance and polymorphism of OOP, a foundation class library of small satellite software is designed, the detail design of all base classes is introduced.
利用OOP的封装性、继承性和多态性，设计小卫星软件的基本类库，介绍各个基本类的具体设计思想。
A mechanism for treating different implementations as logically "the same kind of thing" - usually polymorphism is implemented via interface implementation and class inheritance.
l一种逻辑上做相同事情，但却有不同实现的机制。我们通常称之为多态机制。
Hierarchy of class template is generated due to the combination of class template and inheritance.
由于类模板与继承的结合，产生了所谓的类模板的层次结构。
Some concepts such as module, communication between modules, exchanging, class, method, inheritance, message sending and receiving are introduced in and directly supported by the interpreter.
它同时引入了模块化、模块间的通讯、切换、类、方法、继承、消息发送及接收等概念，并提供对这些概念的直接支持。
These characteristics include objects, methods, inheritance, class library, durability, query, query optimization, integrity, concurrency, performance and schema modification.
这些特征包括：对象、方法、继承性、类库、持久性、查询、查询优化、完整性、并发性、性能和模式修改。
Such "Is a" relationships are very important in class designs, but it's easy to get carried away and end up in a wrong design with a bad inheritance.
类设计中的这种“是一个”的关系是非常重要的，但是你很容易被迷惑而做出错误的类继承设计。
In software design, the using of encapsulation and inheritance of class improved the flexibility of system.
在软件设计中，采用了类的封装和继承技术。
