这个程序是幅值谱中校正频谱峰值的比值校*，可以自设定校正谱峰值的个数，比值校*还可以校正相位，校正的结果很准确-This procedure is correction of the amplitude spectrum of the ratio of the peak spectrum correction method, correction can be set from the number of spectral peaks, the ratio correction method

VC++6.0 实现变压器故障诊断改良三比值法的编写，同时实现txt文件的读写。-Use VC++6.0 to realize transformer fault diagnosis with improved three ratio method, and the same time .

ostu分割法实现代码，找出最大类间方差与最小类内方差比值最大的阈值，进而实现对图像的分割-Implementation code otsu segmentation method to find within Otsu class variance ratio of the maximum and minimum thresholds, so as to realize image segmentation

基于傅里叶变换后的峰值和次峰值的比值对非整周期fft的幅值和相位进行校正，其中添加不同窗函数。(Based on the ratio of peak to sub peak after Fourier transform, the amplitude and phase of non periodic FFT are corrected, in which different window functions are added.)
