摘　　要：给出了计算探测器通量的物理模型及其解析表达式 .采用直接抽样法和倒易方法计算探测器的通量 ,得到了一致的结果 .计算实践表明 ,倒易方法有助于加速 Monte Carlo方法的计算 ,从而大大提高了 MontePhysical model and the analytic expression for calculating the flux of the detector are given. The direct sampling and the reciprocity method are applied to the calculation of the flux measured by a detector. Consistent results are obtained by using both the methods. The calculation indicates that the reciprocity method is useful for the acceleration of Monte Carlo calculation, and hence will help very considerably raise the efficiency of the Monte Carlo method.
