改变语言顺序：装饰器模式（Decorator Pattern）是一种结构型设计模式，它允许在不改变对象自身的基础上，动态地添加功能和行为。装饰器模式通过将对象包装在一个装饰器类中，来实现对对象的增强。

Decorator Pattern is a structural design pattern that allows adding functionality and behavior to an object dynamically without altering its own structure. The purpose of the Decorator Pattern is to enhance objects by wrapping them in a decorator class. This pattern achieves object enhancement by adding decorators to the original object, which can be added or removed at runtime.
