动态类，您可以添加额外的动态PARAMS在运行时的对象。

Dynamic class allow You to add additional dynamic params to object in run-time .

例如：雪碧心不是动态的，所以你不能做这样的事情：

For example : Sprite isnt dynamic , so You cannot do thing like :

var sprite:Sprite = new Sprite ();
sprite["value"] = 10; // this will throw ReferenceError

不过，影片剪辑是动态的，例如，允许你添加动态PARAMS：

But MovieClip is dynamic instance that allow You to add dynamic params :

var mclip:MovieClip = new MovieClip();
mclip["value"] = 10;

若要类实例的动态，你必须动态的关键字添加到声明：

To make class instance dynamic , You have to add 'dynamic' key word to declaration :

public dynamic class MyClass { ...
