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

Polylactic acid (PLA) is a new bio-based and renewable biodegradable material, which is made of starch raw materials proposed by renewable plant resources (such as corn). Starch raw materials are saccharified to obtain glucose, then glucose and certain strains are fermented to produce high purity lactic acid, and polylactic acid with certain molecular weight is synthesized by chemical synthesis method. It has good biodegradability, can be completely degraded by microorganisms in nature under specific conditions after use, and finally generates carbon dioxide and water without polluting the environment, which is very beneficial to environmental protection and is recognized as an environment-friendly material. This thing is actually a long piece, and then "curled up" in it and wrapped in a cylinder shape. What's the use? You will see it in a short time.
