且不动声色，道：我再问旁人去。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).几处竹舍掩映在林木之，一众盗匪围坐在篝火之旁，商议军情。同时，也求一下收藏和推荐票，数据越好，月下写起来，当然也就越有动力。第2季的第一个故事是DRAGONFLY比赛。以能让人联想到未来的国家PIFFLE国作为舞台，小狼、黑钢、法伊以及小樱将操纵飞行器，围绕优胜奖品“羽毛”展开华丽的比赛。由于黑钢老师的锻炼效果而各方面成长的小狼，和拿回几片记忆羽毛而变得精神的小樱。任何困难都无法阻碍，向着目标前进的狼和樱大活跃！我们最原始的恐惧之一就是对未知的恐惧编织了一系列故事。感谢书友【新月妖娆】、【欧吧擦你妹哟。
