关于Ising模型的相变过程

A Discussion of Ising model

一维Ising模型没有相变,二维Ising模型具有相变.文章主要利用计算机模拟长度不变宽度逐渐加宽的Ising模型,并做出一维Ising模型过渡到到二维Ising模型时能量随温度的变化曲线,将结果比较,讨论Ising模型从一维无相变过渡到二维有相变的变化过程.

There is no magnetism transition under one dimension of Ising model. However, under two dimension the Iaing model presents such phenomenon at a certain temperature. This assay, using the advantage of computer, simulated a width changing while length unchanging Ising model, figured out the relationship between energy and temperature under different situation, then compared the results, finally, discussed the process of how such phenomenon took place.
