利用三维物体、扫描仪和Web浏览器研究巴西坚果效应历史线
Studying Brazil-Nut Effect History Line using Disk-Formed Objects, Scanner, and Web Browser
摘要：
利用圆盘状物体对巴西坚果效应（BNE）的二维颗粒结构快照进行了物理建模，按钮和磁性别针。这些BNE配置是人为设计的，以模仿在实验中观察到的真实的。计算机扫描仪用于捕获配置。然后使用运行配备有JavaScript代码的HTML的Web浏览器将获得的图像数字化，该代码主要仅用于这项工作。从数字化过程中获得所有颗粒位置（颗粒床和侵入物），随后使用最简单的模型进行分析，即，势能由于最小能量原理（MEP）表明一个封闭系统应该以最小的内能进入它的状态，我们的BNE系统也必须遵守它。颗粒的压实起着重要的作用，使系统能够以最小的势能实现其构型。
英文摘要：
Grains configuration snapshots of Brazil-nut effect (BNE) in two-dimension are physically modeled using disk-formed objects, e.g., buttons and magnetic pin. These BNE configurations are artificially designed to mimic the real ones observed in experiments. A computer scanner is used to capture the configurations. Obtained images are then digitized using web browser running a HTML equipped with a JavaScript code, which is built mainly only for this work. From digitization process all grains positions (granular bed and intruder) are obtained, which is later analyzed using the simplest model, i.e., potential energy. Since the minimum energy principle (MEP) suggests that a closed system should go to its state with minimum internal energy, our BNE system must also obey it. Evolution of only the intruder seems to violate MEP but not for the whole system. Grains compaction plays important role, so that the system can achieve its configuration with minimum potential energy.
