长期以来,为了提高火炮弹药的效能,军事工程技术人员不仅努力改进装药本身,而且还赋予弹丸以“智能”。在第二次世界大战末期,对地测距引信首次在炮弹上应用了电子学,但是,由于容纳体积小和炮弹所经受的极端环境,直到最近,这方面的进展仍然相当缓慢。 For a long time, in order to improve the effectiveness of artillery ammunition, military engineering technicians not only worked hard to improve the charge itself, but also given the projectile “intelligence.” For the first time in the late World War II, ranging fuzes applied electronics to artillery shells, but until recently, progress in this area was still rather slow due to the small size and the extreme conditions experienced by the shells.
