最近十年来，人们在研究和发展球形药形罩空心装药方面产生了极大的兴趣．这是因为它们在特种弹药的实际应用中提高了弹药性能．本报告提供的是半球形药形罩空心装药的特性测试．概要地说明了射流形成的过程，给出了典型射流特性作为装药几何形状的函数，叙述了药形罩材料的作用．另外，还研究了炸轰波形成器和各种炸药的影响．这种空心装药的重要特点是药形罩形成的杵体弹丸有高的终点弹道效应，这一点对于应用来说是很重要的．
In the recent decade, there has been great interest in the research and development of hollow chargers for spherical drug chests. This is because they improve the performance of ammunition in the practical application of special ammunition. This report provides characterization of hemispherical drug-coated hollow chargers. The process of jet formation is briefly described, and the typical jet characteristics are given as a function of charge geometry. In addition, the impact of bombers and various explosives has also been studied. An important feature of this hollow charge is the high terminal ballistic effect of the pellet projectile formed by the mask, which is important for the application.
