对突入低近空的快捷或遮蔽目标，本文以严谨的射击学原理证明：存在着三种只对高炮才有的射击时机，阐明了高炮的不可替代性 | 并通过处于同一点上的高炮与防空导弹对同一航路上同一目标的射击过程对比，论证了高炮与防空导弹在近程防空反导中的互补性。

For a rapid and sheltered goal entering low or nearby air, the paper shows with strict shooting principle that there exist 3 kinds of shooting opportunities possessed by archibald alone, which illustrates that archibald cannot be replaced. Through contrasting processes, in which the archibald and the antiair?craft missile are located at the same point and shooting at the same goal in the same route, the paper demon?strates the complementarity of archibald and antiaircraft missile in low range air and anti-missile defence.
