开发人员所赞同的一点是：编写良好的代码易于维护，依赖性倒置原则是进行可维护性设计的可靠方法。

One thing developers have come to agree on is that well-written code is maintainable, and the Dependency Inversion Principle is a sure way to design for maintainability.

特别是，对象系统设计的目标是分割系统状态，从而达到软件设计中面临的同样的可维护性和可扩展性的目标。

In particular, the goal of object system design is to partition the system state to meet the same goals of maintainability and extendibility faced in software design.

这样的分离是良好设计的标志，并可以增加可维护性。

Such a separation is a hallmark of good design and increases maintainability.
