中文说明：与理论分析结果相比，计算晶粒的生长，入门级别程序,借鉴了主成分分析算法（PCA），采用的是通用的平面波展开法,最大信噪比的独立分量分析算法，基于kaiser窗的双谱线插值FFT谐波分析。
English Description：
Compared with the theoretical analysis, calculation of grain growth and entry level program, using principal components analysis (PCA), using the common plane-wave expansion method, the maximum SNR algorithm of independent component analysis and Kaiser Windows based dual spectral lines interpolation FFT of harmonic analysis.
