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 continuous slowing down approximation is described, and a new Monte Carlo calculation model for calculating the track structure and energy deposition distribution of heavy ions in the equivalent biological tissue - liquid water is established. The purpose is to establish the relationship between the intensity of cell damage and the extent of damage and heavy ion parameters, and to theoretically explore the mechanism of heavy ion biological effects.
