彈丸

Use of two-stage light gas guns is one of the techniques extensively used to achieve hypervelocity projectiles. 二級(jí)輕氣炮是超高速?gòu)椡栩?qū)動(dòng)技術(shù)中使用最廣泛的技術(shù)之一。

Finally, for flight projectiles with different initial conditions, the radian characteristic of different spectral bands is analysed. 最后分析了彈丸以不同初始條件飛行時(shí)在不同光譜波段內(nèi)的輻射特點(diǎn)。
