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孙掌柜便将郑家三少爷从福缘茶楼过来的事说了，意在提醒他：今日之事不是郑三少爷故意针对姜家，而是碰巧遇见的。布莱恩（布莱德利·库珀 Bradley Cooper 饰）是一名军火承包商，年纪轻轻的他便在行业内闯出了一片属于自己的天地，攀登上了事业的最高峰。某日，他被上司派往夏威夷火奴鲁鲁军事基地，那里正在进行一项间谍卫星的开发和研制，需要布莱恩的监督，布莱恩兴致勃勃的踏上了旅途。让布莱恩没有想到的是，在目的地，等待着他要和他一同共事，是一位名叫艾莉森（艾玛·斯通 Emma Stone 饰）的女飞行员，艾莉森冷若冰霜而又不苟言笑，着实是一个严肃而又无趣的女人，这令布莱恩感到十分郁闷，与此同时，布莱恩对前女友崔西（瑞秋·麦克亚当斯 Rachel McAdams 饰）依然抱有着不切实际的幻想，他联系到了崔西，企图和她破镜重圆。Article 44 The fire control institutions of the provincial public security organs shall establish and improve the social fire control technical service information system, publish the relevant information of the fire control technical service institutions and their registered fire engineers, publish the practice, integrity, supervision and management information, and provide relevant information inquiry services for the society.So as to assist in supporting the shooting trunk.
