渗流相变实验

Percolation Experiment

基于渗流相变理论设计了可重复使用的渗流实验仪器。在大学物理甚至高中物理一次实验课的时间内,利用渗流实验仪进行测量不同随机占据概率下的电流,对四次实验结果进行平均后,绘制相对电导率与占据概率曲线,可以获得与文献[9]相似的结果,再现渗流相变的存在。

A simple reusable percolation experimental instrument is designed based on the percolation theory. This experiment can be carried out at an undergraduate physics laboratory,or even at a high school laboratory. By measuring currency under different occupied probability,a curve representing the relative conductivity as a function of concentration p,which is averaged over 4 experiments,is presented. This curve has the same result with the reference and demonstrates the existence of percolation phenomena.
