An approximate treatment of neutron slowing by elastic collisions with nuclei of a moderating material in a nuclear reactor is developed on the basis of a compact treatment of elastic collisions previously published in this journal [B. C. Reed, Am. J. Phys. 86(8), 622 (2018)]. The analysis is straightforward enough to be presented to lower-level students and gives results in good accord with more sophisticated treatments.

弹性碰撞引起的中子减速的简化处理

基于先前发表在本期刊 [BC Reed, Am. J.物理。86(8), 622 (2018)]。该分析足够直接，可以呈现给低水平的学生，并给出与更复杂的处理方法非常一致的结果。
