论文摘要
我们提出了一个基于液体吸收模型的简单活动，该活动使中学生可以探索数学模型的用途，并获得对结合能概念的直观理解，尤其是阳性结合能的重要性。使用提供的电子表格作为补充材料，学生可以对模型的不同系数进行简单的操纵，以了解其五个术语中每个术语的作用。学生可以使用电子表格通过使用真实原子质量数据优化协议来确定模型参数。 ％随后将用于预测Segré图表的存在极限，并找到中子恒星的最小质量。该活动可以用作关于理论模型的讨论的起点，在描述实验数据及其对未开发政权的预测能力时，它们的验证。
We present a simple activity based on the liquid-drop model which allows secondary school students to explore the uses of mathematical models and gain an intuitive understanding of the concept of binding energy, and in particular the significance of positive binding energy. Using spreadsheets provided as Supplementary Material, students can perform simple manipulations on the different coefficients of the model to understand the role of each of its five terms. Students can use the spreadsheets to determine model parameters by optimising the agreement with real atomic mass data. %This will subsequently be used to predict the limit of existence of the Segré chart and to find the minimum mass of a neutron star. This activity can be used as the starting point of a discussion about theoretical models, their validation when it comes to describing experimental data and their predictive power towards unexplored regimes.
