The following procedure is to use the state mode to improve the light. When it comes to encapsulation, the behavior of the encapsulated object is generally preferred over the state of the object. But the opposite is true in state mode, The key to the state mode is to encapsulate each state of the thing into a separate class, and the behaviors related to this state are encapsulated inside this class, so when button is pressed, only the request needs to be delegated to the current state object in the context, and the state object will be responsible for rendering its own behaviors. At the same time, the state switching rules can be distributed in the state classes in advance, thus effectively eliminating a large number of conditional branch statements that originally existed.

Mobile phone address book memos, operating system backup points, database backup, etc. in life are all applications of memo mode. Memorandum mode captures the internal state of an object without destroying the encapsulation and saves the state outside the object, so that the object can be restored to its original state later. The specific structure diagram is as follows:

One last thing on this subject, The 7.62 mm traced armour-piercing firebombs fired by the 81-1 family, Although the name is a little long, But compared with ordinary munitions, The difference is still well understood: Tracing and burning are simple, Is to add two corresponding drugs, The armor piercing is to replace the steel core behind the bullet's brass back armor (also known as bullet head) with a harder tungsten alloy core with stronger penetration to hard targets. The latter is also the tail-stabilized shelling penetrator used on the third generation of modern main battle tanks (abbreviation: APFSDS) is one of the two main materials (the other is the notorious, highly radioactive depleted uranium penetrator core, The user country is mainly the United States, while China mainly uses tungsten alloy penetrators, Less pollution and better performance, The United States does not need to. First, the United States does not pass the standard of tungsten treatment technology. Far from the level of our country, Secondly, the United States is a tungsten-poor country. It also wants to fully use tungsten alloy bombs, But it can't be used, But as a nuclear Power, There is a lot of depleted uranium as nuclear waste, so depleted uranium is selected as a substitute. As for tungsten alloy and depleted uranium, after putting aside the key additional condition of radioactive pollution, the pure question of who is better in armour-piercing performance is not directly related to this article, so it will not be described in detail).

《中国神探》，别名神探谷梁。该剧描绘的警官大学教官谷粱是一位有着丰富破案阅历的资深警探，人称“神探”。但乍一看去神探并没有传说的那样神奇，他相貌平平，不修边幅，有着几分幽默，好尝几口佳肴。时不时忙里偷闲，找个机会到遍布各地的学生们那里转一转，摆摆教官资格，尝尝南北风味。甚至乐于在电视剧组中客串一把，好挣几个烟酒钱。但或许是由于“神探”的名声所累，他所到之处，总有一件件案子撞到他的眼中，他也因此而一次次身不由已地介入案情，和年轻的刑警弟子们相互搭档又彼此较劲，以缜密的推理逻辑排难析疑，在嘻笑怒骂间将一个个疑难案件逐一侦破，显露出一个中国警官真正的“神探”本色。
