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这选婿。讲述了出身富贵的女婴宋连城自出生之日起就被母亲指使与买来的男孩恒泰互换。从此两人命运背离，连城浪迹在勾栏烟花巷，恒泰成长于巍峨的将军府。两人却鬼使神差相遇并相知相爱。连城得以重入将军府，但两人的爱情遭遇各方阻击，连城更是连遭公主迫害。所幸不屈的爱情将错乱的人生纳入正轨，冤家坦然相对时，已是霜满头。可恨世人太过愚蠢，不去关注那些物理定律、永恒至理、宇宙奥秘，反而对一些狗屁不通的小说、诗歌大加追捧。如今日新月异的科技让人类看到惊人的奥秘，在神秘的蛇的国度里它们惊人能力，是在遗失的世界中急速形成而进化在人类群体中存在着。Create a new drawing file, Click on the "Elevation" tool in the tool palette, and the command prompt line displays "Specify the insertion point or [Base Point (B)/Scale (S)/X/Y/Z/Rotation (R)]".
