本文提出了用一维可压缩流体理论分析求解高速射流侵彻靶扳的一个解析方法。运用该方法，能根据射流速度而得到侵彻过程中清晰的亚、超音速流动图象，并能简便求得侵彻速度和深度，从而具有一定的实用价值。本文在分析推导中还得到了激波波阵面上声速的解析表达式和衡量材料可压缩性的一个新指标。这对于研究材料的高速变形具有一定意义。
Abstract
In this paper, using one-dimensional theory of the compressible fluid, we have put forward a method to solve and analyze the jet penetration on target. For different region of jetˊs velocity, we can get the corresponding configurations of subsonic or supersonic flows both in jet and in target, and work out the penetrating speed and depth easily. So, the method has a certain practical values. In the paper，we have also obtained an analytical expression of sound speed behind the shock, and a new index to evaluate tte compressibility of materials. These are of gre， at significances in the researches of high-strain rate phenomena.
