| 摘 要： | 根据我们建立的径迹结构Monte Carlo计算模型,计算了低能电子在液态水中径迹范围内DNA分子片段模型和染色质丝片段模型区域内的能量沉积频率分布,结果与OREC和CPA程序结果进行了比较,这些计算结果为解释低能重离子注入生物体造成深部生物效应而提出的一种物理机制──软X射线机制提供了理论依据.

| Abstract: | Based on our Monte Carlo calculation model, frequency distributions of energy deposition in areas of DNA segment and chromatin fibre segment by a low energy electron are calculated in liquid water. The results are compared with those of OREC code and CPA code. These calculated results are theoretical evidence of soft X ray mechanism which was suggested by us in order to explain physical mechanism of deep biological effect produced by low energy heavy ion implantation. |
