instantiation and invocation of the object itself does not make much sense, it is equivalent to a variable. It is better to understand an object as an array. In this case, the objects in each of the initialized scripts will be created "" using object-oriented in the program will certainly consume performance, but we use this way to be too convenient for development speed and maintenance. That's why we use them: Design Patterns "The structure of a monolithic

The standard for determining if the transistor is entering the saturation zone is ibxβ> Ic (max), because the analog circuit book in college was written on the condition that the NPN transistor is in the saturated zone is ube>0 ubc>0, but in single-chip microcomputer applications, the general collector is connected to VCC via a resistor, So the base of the voltage can not be higher than the collector, so I think it is also possible to understand that the IB increases, IC = Ibxβ also with the inc

divide into three different micro-services. But in a layer of organization, there will be multiple users, and a user will have their own multiple customers, so there is no way to completely separate the three services (or related relations), this does not accord with the previous understanding. However, the relationship between the three is necessary, the existence is reasonable, then it should be three micro-services and mutual cooperation and independent relationship.
