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).Deliberate practice does not deny the importance of situation, but in some best sellers, the mainstream methods that have been confirmed by learning science are placed in a humble corner. Tacit knowledge, which is closely related to learning, is ignored. A large number of studies in learning science show that the best way for adults to learn is not to practice alone, but to learn in situations. Effective learning is to enter relevant situations and find one's own "learning community". At the beginning, learners turn around important members and do some peripheral work.
