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 Baidu(2) There are seven structural modes: adapter mode, decorator mode, agent mode, appearance mode, bridging mode, combination mode and element sharing mode.为当红小鲜肉订制书橱？！还可以自由出没他的私宅？！要是被迷妹们知道的话，大概会被羡慕嫉妒恨吧……可他怎么和屏幕上的温柔暖男形象差别那么大？傲慢无礼不说，还根本不看书！聘请她的目的，竟然只是为了让她读剧本！Excuse me???In fact, the core point of Erickson's deliberate practice is that those who are at the middle and upper levels have a strong memory ability: long-term memory.

It is the direction and essence of deliberate practice.海伦·亨特加盟亚当·兰道([奇机少年])执导恐怖片[找到了](I See You，暂译)。一位儿童诱拐调查员忍受着妻子出轨的痛苦，妻子也因内疚逐渐变得情绪失常。邪恶之力渐渐入侵他们的家庭，两人的儿子也因此陷入了致命危险当中。本作将于今夏在克利夫兰开机。　　最近在央视的动画基地制作完成了一部新动画片——《小鲤鱼历险记》。老实说，最初对于这部片子是不敢兴趣的，不仅是名字不够别致，还因为国产的动画总是让我们从一次次期待变成了一次次失望。可这次，在我看完了第一集之后，要不是故事取材明显是中国风，光看人设和故事节奏的把握，我都会以为这是一部国外的作品。可以说，在中国动画最弱的一环——人物个性的把握上，这部动画已经做到了80分以上了。能让我这个资深的动漫迷净下心来观看，并期待着后继的发展，一部动画能做到这一点就已经足够了。因为它，我再一次对国产漫画有了信心！在很多人心目中，张三丰必然是仙风道骨、仪态非凡。
