本文介绍了模板方法设计模式的基本概念，解释了如何通过抽象基类实现不变部分的算法，并允许子类在必要时重新定义算法。此外，还对比了模板方法与策略模式的区别。

Template method lets abstract base class (this is the class to implement the algorithm) to implement invariant algorithm. The subclasses can redefine the algorithm when necessary. By this mechanism, we can reuse the code.
Normally, factory method is used by template to get instance of concrete subclass. Compared with template method, strategy uses delegation to vary the algorithm.
