本文用1961-2006年广西88个气象观测站的各月雨量资料，北半球500百帕月平均高度场资料(576个格点)，国家气候中心提供的部分环流特征量资料，通过EOF分解、合成分析、S(A practical estimate on the credibility formula is presented, where a piecewise linear function is taken as the approximation of the prior distribution and applied to the credibility theory. The convergence of the approximation is analyzed.)

数字图像快速傅里叶变换（FFT）。将图像转化成二维灰度图像后再做FFT变换，并输出变换后的幅值图。(Digital image fast Fourier transform (FFT).The image is transformed into a two-dimensional gray level image and then the FFT transformation is made, and the amplitude diagram is output after the transformation.)

此程序用提升法实现第二代小波变换 用的是非整数阶小波变换 采用时域实现,步骤先列后行 正变换：分裂，预测，更新； 反变换：更新，预测，合并 只做一层（可以多层，而且每层的预测和更新方程不同）(This procedure achieved by lifting the second generation wavelet transform with a non-integer order wavelet transform time-domain realization of transformation steps, then over are: split, predict, update inverse transform: Update, forecasting, consolidation only a layer of ( can be multi-layer, and each prediction and update equations are different))
