用ＭｏｎｔｅＣａｒｌｏ法模拟计算了３０ｋｅＶ和２００ｋｅＶ的Ｎ＋与１１０ｋｅＶ的Ｆｅ＋在模拟细胞中本身及级联离子非弹性散射产生的电子、分子振动的能量沉积；讨论了电子、分子振动的总能量沉积的深度分布。从计算结果看，能量主要集中分布在样品的浅层，能量沉积值非常大。在将注入量为１０１５／ｃｍ２的３０ｋｅＶＮ＋注入生物材料时，定性讨论了生物材料的局部温度。
Monte Carlo method was used to simulate the energy depositions of electron and molecular vibration generated by the inelastic scattering of 30keV and 200keV N + ions and 110keV Fe + in simulated cells and cascaded ions. The depth distribution of total energy deposition of electrons and molecular vibration . From the calculation results, the energy is mainly concentrated in the shallow sample, the energy deposition value is very large. The local temperature of the biomaterial was qualitatively discussed when implanting 30 keVN + into the biomaterial at a dose of 1015 / cm2.
