The Richter substitution principle says that wherever a base class can appear, subclasses can certainly appear. LSP is the cornerstone of inheritance reuse. Only when derivative classes can replace base classes and the functions of software units are not affected can base classes be truly reused, and derivative classes can also add new behaviors to base classes. The Richter substitution principle is a supplement to the "open-close" principle. The key step to realize the "open-close" principle is abstraction. The inheritance relationship between the base class and the subclass is the concrete realization of abstraction, so the Richter substitution principle is the specification of the concrete steps to realize abstraction. --From Baidu被一个蔑视的情人折磨并留下来死去，一个女人发现自己内心的力量可以恢复并对她的施虐者进行报复。改编自同名经典科幻片的美剧《12只猴子》，日前确定将于2015年1月16日晚间登陆美国NBC电视台Syfy频道，加长版预告片也随之曝光。2.
