本文利用多区首次碰撞几率,推导计算圆柱形控制棒黑度的公式。棒的各层可由不同介质组成,并允许包括一个黑芯棒。计算精度可根据需要人为地控制。
In this paper, the formula of calculating the blackness of cylindrical control rods is deduced by using the probability of first collision in multiple zones. The layers of rods can be composed of different media and allow the inclusion of a black core rod. Calculation accuracy can be artificially controlled as needed.
