随着第四代反应堆以及先进核能利用系统的发展，对中子核数据提出了高精度、多核素、宽能区的新要求。目前，中国核数据评价库（CENDL库）中相关核裂变的数据较缺失，不足以满足当前核能发展的需求。因此，建立面向中子核数据需求的可靠计算方法和工具变得极为重要。本文基于Monte-Carlo方法建立了裂变碎片质量动能计算模型，研究了中低能中子诱发232Th（n，f）反应发射中子前裂变碎片的分布特性。对于裂变碎...

为合理预测某型液体运载火箭爆炸生成碎片的危害区域，保证地面发射场设施设备及人员的安全，采用Monte-Carlo方法模拟了爆炸碎片的飞散轨迹，分析了碎片初速和火箭爆心高度对碎片散布的影响。结果表明：火箭爆炸碎片初始速度是影响碎片最大飞行距离的重要因素，火箭爆炸碎片的最大飞行距离随着碎片初始速度的增大而增大，但随着碎片初始速度的增大，碎片最大飞行距离的增长幅度慢慢减小；随着爆心高度的不断增加，爆炸碎...
