中文说明：这是我自己编程的代码，利用的方法是当前计算效率最高的谱分析计算，利用相场模型模拟了二元合金的极分解过程，望大家多多交流学习！
English Description：
This is my own programming code, using the method is currently the most efficient spectral analysis calculation, using the phase field model to simulate the polar decomposition process of binary alloy, hope you can exchange and learn more!
