摘　　要：为了更清晰地表现方程的刚性,采用可视化方法对点堆动态方程进行仿真,研究和分析该方程的刚性性质.结果表明,在可视化条件下,能够较为直观地了解点堆动力学方程的刚性性质,有助于更加全面认识和掌握该方程.The point reactor neutron kinetics equations were a set of stiff equations. It is diffi- cult to understand the stiffness in mathematics. Visualization method could make abstract concept visualized. The stiffness nature was discussed and analyzed by simulating the kinet- ics equations based on visualization method. The simulation result showed that the stiffness of point reactor neutron kinetics equations could be indicated clearly in the visual condition. It＇ s helpful to master the point reactor neutron kinetics equations.
