The semiempirical abrasion/ablation model has been successful in generating a large nuclear data base for use in the study of high charge and energy (HZE) ion beams, radiation physics and galactic cosmic ray shielding. The cross sections generated agree with the measured HZE fragmentation data to the degree that different experimental groups agree among themselves. Several improvements in the model have been made including a Coulomb trajectory correction, an improved treatment of nuclear attenuation factors, an improved second order correction to the spectator fragment excitation spectrum, a pre-equilibrium emission process, and competitive equilibrium emission of additional hydrogen and helium isotope fragments.
半经验磨损/烧蚀模型已成功生成大量核数据库，用于研究高电荷和能量（HZE）离子束、辐射物理学以及银河系宇宙射线屏蔽。所生成的截面与测量的HZE碎片数据相符，不同实验组之间也达成了一致。该模型已进行了多项改进，包括库仑轨迹校正、对核衰减因子的改进处理、对旁观碎片激发谱的二阶校正改进、预平衡发射过程以及额外氢和氦同位素碎片的竞争平衡发射。
