1·The prototype chain does not provide any protection in that same sense.

原型链不在同一意义上提供任何保护。

2·Therefore, the prototype chain can be used to implement inheritance, as you'll see later.

因此，该原型链可用于实现继承（在后面讨论）。

3·Returns a Boolean value indicating whether an object exists in the prototype chain of another object.

返回一个布尔值，该值指示对象是否存在于另一个对象的原型链中。

4·In a similar vein, you also have no guarantee that your object's prototype chain has not been altered.

同理，你也没有保证你的对象的原型链没有改变。

5·A prototype chain is a finite chain of objects which is used to implemented inheritance and Shared properties.

原型链是一个由目标构成的有限目标链因为完成担当和同享属性。

6·The returned properties are both those that exist on the object instance and those inherited through its prototype chain.

返回的属性包括对象的实例属性和它从原型链继承而来的属性。

7·This provides greater maintainability and flexibility since you now control the methods you expose directly without relying on the prototype chain.

这提供了更大的可维护性和灵活性，因为你现在你直接暴露控制方法不依赖于原型链。

8·Lastly, the closure structure more closely follows the Law of Demeter since your object would, theoretically, be reaching through via the prototype chain.

最后，闭合结构更接近于得墨忒耳法自你的对象，从理论上讲，是“通过”通过原型链。

9·You'll set a prototype instance variable to point to the parent in the inheritance chain.

方法是设置 prototype 实例变量使其指向继承链的父。

10·A mechanism reverse design technique was presented based on chain codes similarity analysis, and followed by a developed prototype system as an example.

基于链码及链码匹配的相似度分析，提出了机构反求设计的方法，并开发了原型系统。
