| 摘 要： | 空间辐射环境中的抗辐射是航天事业发展中的一个重要课题,研究方法有实验和计算机模拟两大类,其中实验研究由于实验条件、实验次数等方面因素使其具有一定的局限性,相比之下,计算机模拟研究具有其独特的优势,而程序的功能是否完善直接关系到模拟的可靠性。因此,该文针对SHIELD程序的不足之处进行改进,主要包括移植更复杂的几何模型,添加能谱入射方式,在输出上增加了能量角分布、深度剂量分布等功能,并把改造后的程序模拟复杂卫星模型,结果表明改造后的程序能更真实地进行模拟。 |

| Abstract: | The problem of anti-radiation in a spatial radiation environment is an important issue in space mission development.Way of research includes experiment and computer simulation.The experiment has its shortcoming,such as experiment condition and times,whereas simulation has its own advantage.Whether the function of program is effective would influence the credibility of the simulation.Therefore,the SHIELD code was modified to calculate the anti-radiation in complicated geometries with various particle incident analyses and angle,energy and dose distributions.A complicated model was then simulated.The results show that the modified code has its validity. |
| Keywords: | SHIELD code geometry module conicoid radiation environment simulation |
