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).再者，斩杀龙且的事迹不日就会传遍天下，他灌婴必须为人所称赞和敬佩，可以说是名利双收，心情自然十分愉悦。吴梅也逐渐适应了如今的身份和生活。For example, if we want to implement a JS function, Such as form validation, Then if we don't use the policy pattern in javascript described in the previous chapter to solve the form validation encapsulation code, It is a temporary form validation function written by itself. Certainly without any encapsulation, Then at this time, we will pop up a prompt to the user for whether the two values are equal. If there is a form verification on another page, their judgment method and business logic are basically the same, but the comparison parameters are different. Should we consider writing a form verification code again? So now we can consider using the template method pattern to solve this problem. Common methods are extracted, and different methods are implemented by specific subclasses. This design code also has the advantages of stronger scalability and better code ~还要大，再猜。而如今的浙兵，完全没有正面交战的能力。当多米尼还是个孩子的时候，他亲眼目睹了美国顶级罪犯杀害了他的在保加利亚与腐败集团作斗争的警察父亲。几年后，他试图为父亲的死亡报仇，但却被判了企图谋杀15年监禁。在狱中，他遇到了美国的照片记者，并分享他敌人的资料。
