摘要 针对MCNP在某些情况下模拟脉冲高度谱时遇到精度不能满足要求的问题,初步讨论了响应函数和分段模拟这两种可能的解决方法的原理和基本实现过程。并结合工作讲述了一例应用分段模拟法生成脉冲高度谱的算例。 What is focused on is how to enhance the accuracy of pulse height tally simulation by MCNP in some cases where the relative error of MCNP result is large.Two possible methods(response function and simulation-by-parts) and an example is discussed.
