Factory Pattern: Factory Pattern is a frequently used pattern. Classes implemented according to Factory Pattern can generate instances of one of a group of classes according to the provided data. Usually, this group of classes has a common abstract parent class and implements the same methods, but these methods perform different operations for different data. First of all, we need to define a base class. Subclasses of this class implement methods in the base class through different methods. Then you need to define a factory class that can generate different subclass instances according to conditions. After getting an instance of a subclass, developers can call methods in the base class regardless of which subclass instance is returned.寻找到了很好的突破口。(2) Electromagnetic time relay has short delay time (0.3 ~ 1.6 s), but its structure is relatively simple and is usually used in power failure delay occasions and DC circuits.The minimum center spacing between the pins of adjacent components of DIP devices shall not be less than 2.0 mm.
