The results indicate that the penetration depth does not increase with the increasing hit velocity, which is different from the phenomena of the penetration of concrete and rock.
这与弹体在普通混凝土和岩石中的侵彻现象明显不同，主要是由侵彻弹体发生破坏失去了继续侵彻能力造成的。

Penetration performance in surface layer of concrete target was analyzed by stress wave damage theory, calculating method base on "simplified equivalent resistance line" was presented.
从应力波表层损伤理论分析了混凝土表层“开坑区”的侵彻特性，提出“简化等效阻力线”的计算方法；
