摘　　要：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 multi-region first collision probabilities are used to derive the formula for calculating blackness of a cylindrical control rod.It is permitted that the different layers of the control rod consist of different materials and there can be a black core cylinder contained in the control rod.The calculation accuracy can be controlled artificially according to different requirements.

关 键 词：控制棒 黑度 计算 圆柱形
