紫茄就不好意思地笑了，点头说是。The Liskov Substitution Principle (LSP) is one of the basic principles of object-oriented design. 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 BaiduPeter饰演的是一个警察而Margie则饰演一个红遍泰国的坏女配。在这虚拟的世界里， Margie这个时尚洒脱的女演员被迫去做卧底，充当 Peter 的诱饵协助他调查一个重要的大毒枭。嗯，杨子当县令的时候他也见过两次……不对，抄家的时候，他还见到了那个湖州知府，就是那个公孙匡，虽然是个坏官，好歹也是知府……还是不对，周夫子可是当过宰相的，比他们都大，他常跟周夫子一桌喝酒呢。　　講就容易！但由 梁詠琪  、潘燦良 、  周家怡 、強尼、 娟姐  、 肥仔 、李炘頤 呢班家長同大人講到出口，又係咪會口不對心，點都偷偷幫小朋友報返個興趣班：「最多?學下樂器?真係好基本咋嘛?」咁呢？Name: JaydenHowever, under the circumstances at that time, I thought these things had little effect, because after we knocked them out, we began to gather in more quantities and launched attacks on positions from all directions. Judging from the form of attacks, they were quite organized and definitely beyond the reach of ordinary wild animals.
