重离子径迹结构的Monte Carlo计算模型

Monte Carlo of Heavy Ion Track Strcture Calculation

摘要: 阐述了一种称之为分段连续减慢近似的方法，建立了新的计算重离子在等效生物组织－液态水中径迹结构及能量沉积分布的ＭｏｎｔｅＣａｒｌｏ计算模型．目的在于建立细胞损伤强度和损伤范围与重离子参量之间的关系，从理论上探索重离子生物效应的机理． A method called segmented continuous slow down approximation is explained,and a model of heaVy ion track structure Calculation in equivalent biological tissue-liquid water by means of Monte Carlo is built up. It aims at establishing relations between lesion intensity and range of cells and heaVy ion parameters and invetigating biological effect mechanism by heavy ions in theory.
