弹丸
Use of two-stage light gas guns is one of the techniques extensively used to achieve hypervelocity projectiles. 二级轻气炮是超高速弹丸驱动技术中使用最广泛的技术之一。
Finally, for flight projectiles with different initial conditions, the radian characteristic of different spectral bands is analysed. 最后分析了弹丸以不同初始条件飞行时在不同光谱波段内的辐射特点。
