摘要
为解决确定性输运方法DXTRAN计算小栅元光子能量沉积在DX球附近引入过大粒子权重波动使得计算结果失真的问题,引入了Nested DXTRAN方法,改善了过大粒子权重波动对计算结果的不良影响,提高小栅元光子能量沉积的计算效率,也有利于得到更加可信的计算结果。
To solve the problem of calculating the photon energy deposition of small cells using deterministic transport method DXTRAN which introduce a large weight fluctuation near the DX sphere leads to a deviation of calculation results,Nested DXTRAN method was applied.The negative impact of weight fluctuation was improved.It improves tally efficiency and help to get more reliable results.
